If you have a car that hasn’t been driven in a while you may be wondering if the gas in the tank is still fine or if it needs to be removed and fresh gas added. Here is your answer.

Is Old Gas in the Tank Bad for Your Car? The fast answer

Waste gas is not an issue in almost all cases. Gas that sits slowly goes bad. However, petrol that has stood for even a few months can be redeemed by topping up the tank with fresh petrol. If the fresh gas mixes with the older gas, the engine is working properly. John Ibbotson, chief mechanic at Consumer Reports, says: “The new gasoline mixes with what’s already in your tank and any discrepancy in octane is automatically adjusted by your car’s engine computer.” The adjustment gets the engine running normally again .

What happens when gas gets old?

When gas sits, it begins to break down in a variety of ways. Gasoline loses octane over time. Octane is the flammable component of gasoline. The higher the octane rating (think 87, 89, 93), the better the air/fuel mixture and the better the combustion in the cylinders.

Old gas also loses its volatility — how explosive it is — as it ages. Reducing volatility reduces engine performance. Residues and water from gas combustion can also accumulate in the engine and gas while it is sitting. None of this bodes well for engine function.

How old is too old for gas?

Deterioration occurs from the start, but most gasoline will stay fresh for a month or two with no problems. However, gasoline that is more than two months old can generally be used with only a minor loss in performance. Gasoline over a year old can cause problems such as engine knock, sputtering, and clogged injectors. Bad gas can be drained from the tank to avoid damage to the engine. One caveat to keep in mind is that there is no way of knowing how old the gas is when you first pump it into the car.

What can you do to protect the car when you store it?

Ronald Montoya, senior consumer advice editor at Edmunds, suggests topping up the engine to prevent water from accumulating in the engine and adding a fuel stabilizer to the engine to slow the breakdown of the gas. Fuel stabilizers can extend gas life by up to 15 months. Be sure to add the stabilizer to the fresh gas. Finally, if you can’t keep the car indoors, cover it with an all-weather cover.

Depending on what you mean it may be safe. But do we really know what we mean when we ask the question?

Diesel fuel used to have a long shelf life – US Army regulations from the 1950’s and 1960’s talked about preserving stored diesel for several years. Now you’re probably going to get less than a year if the fuel isn’t treated in some way.

what makes it bad

Diesel fuel goes bad when exposed to something in the environment that accelerates the natural processes that attack its quality. All petroleum fuels, whether gasoline or diesel, are made up of a mixture of molecules of different sizes and lengths. Fuel starts with a series of molecules that are unstable – the “precursors”. Over time, these precursors react with other molecules, starting chain reactions that, given enough time, cause the fuel to gum, varnish, sludge, and become dark and stratified. This end result is what we refer to as “fuel gone bad”.

We’ve talked about it “doing badly” because it’s not working as well as we want it to anymore. Fuel that’s dark and full of sludge or varnish won’t burn properly, will produce black smoke and may not even start an engine if it’s bad enough.

In recent years this has been a slow process, which is why the fuel has been able to make a good living for years. It’s still a slow process today, but it’s much faster than it used to be. The useful life of diesel is now measured in months instead of years.

We have said that fuel goes bad when exposed to environmental factors that speed up these processes. Exposure to air, water, and heat + light are three major environmental factors. Heat and light make a fuel return faster by providing energy to power the chemical reactions that break it down.

Another important factor that is more prevalent in today’s fuels is microbial growth. Since modern diesel fuels no longer have the high sulfur content of the past, there is nothing stopping the growth of microbes in the fuel. Microbes can spoil diesel fuel fairly quickly by multiplying in the fuel, forming biomass and producing acids that attack and break down diesel fuel.

Does diesel fuel go bad? You bet it does, depending on how you handle it.

DIY car maintenance

If you are servicing your own car, van or motorcycle, you need to make sure to take care of the used oil when you change it so it doesn’t pollute your local environment.

If you maintain motor vehicles as your business, this notice does not apply; You must use an approved, registered/licensed disposal company to dispose of your waste oil.

Change your oil safely

Have an oil spill kit ready; You can buy one from auto parts suppliers, major hardware stores, or online. Use a drip pan or specially made drain pan to catch the oil as it drains.

Store your old oil in a suitable container until you are ready to dispose of it. Make sure the container has a secure lid to reduce the risk of spills when transporting it to an oil recycling bank.

Dispose of your oil safely

Don’t pour your oil down the drain or on the floor; They would cause pollution and break the law. If you are found to have caused pollution, you may be prosecuted.

Take your used oil to an oil bank for safe and legal disposal.

To find your nearest oil bank, visit the oil bank’s website at www.oilbankline.org.uk, phone 03708 506 506 or contact your local recycling officer.

Do not mix your used oil with brake fluids or antifreeze. Dispose of other waste liquids from your vehicle separately at local collection points.

If you spill something: 3 points to remember

Never pour, wash or hose down oil down a drain or gully; dispose of properly. Do not mix detergent with oil, this will make the dirt worse. Prevent spilled oil from entering drains by using an oil spill kit or even sand or earth. Bag contaminated material and dispose of as oil contaminated waste.

For advice on an oil spill call the national accident/environment hotline on 0800 80 70 60, the hotline is available 24 hours a day, calls from landlines are free but charges may apply if you have a mobile phone use.

Remember, oil and water don’t mix – please help us separate them.

Some enthusiasts who store their vehicles for long periods may be concerned about the fuel in their tank.

While most are legitimately draining the tank or using a fuel stabilizer, you may want to store fuel at home.

Here’s everything you need to know about storing used fuel and petrol/diesel.

What you need to know about storing fuel in portable containers at home

The current fuel supply crisis has prompted many motorists to panic buy petrol and diesel.

Despite retailers and the government urging drivers to buy only what they need, gas stations in some parts of the country have seen pumps run empty or have been forced to impose spending limits to ration their supplies.

Subscribe to our daily newsletter Subscribe Thank you for subscribing! Sorry, there seems to be some issues. Please try again later. Send…

In some cases, drivers have been seen filling up several gas cans to hoard fuel at home. This means they have a supply now but could face problems later.

Does gasoline become obsolete?

Although gasoline and diesel are made from crude oil that has been lying underground for millions of years, they do not last forever and even have a surprisingly short shelf life.

According to the RAC, when properly stored, gasoline typically has a shelf life of around six months. That means in a tightly closed container at 20 degrees.

At higher temperatures, it degrades more quickly, at 30 degrees, for example, it only lasts three months.

Similarly, if the canister is poorly sealed, the fuel will degrade faster.

In general, diesel will last anywhere from six to 12 months in a portable canister before it starts to degrade. However, as with gasoline, storage can affect its longevity.

Degradation occurs because different chemical elements in the fuel vaporize at different rates, meaning that the chemical composition of the fuel changes over time. While some chemicals vaporize, others react with oxygen, making the fuel “gummy.”

Will stale fuel damage my car?

In most cases, a small amount of stale fuel is unlikely to cause significant problems. If you have used stale fuel or suspect that your car’s fuel tank has leaked, it is best to fill up with fresh petrol or diesel.

However, the older the fuel, the worse the deterioration and potential for problems. So if the fuel has been sitting in your car’s system for a long time (more than six months), it’s worth draining it.

Using petrol that has past its prime can result in poor starting or loss of power due to fuel aging.

In more extreme cases, where the gasoline has oxidized and become “gummy,” solid contaminants can form that can clog the fuel system and other parts of the engine.

Similarly, depleted diesel can lead to the formation of deposits that block sensitive parts of the fuel system and potentially lead to expensive problems.

Can I store gasoline at home?

You can store gasoline at home, but there are several restrictions on how much gasoline you can store at home and where you store it.

The Health and Safety Executive states that individuals can store up to a total of 30 liters in appropriate portable containers or in a single detachable fuel tank.

If you use a metal petrol can, you can store up to 20 liters in one container.

If you use a plastic fuel can, you can store up to 10 liters in one container.

If you store the fuel tanks in a vehicle, you can store no more than 30 liters in no more than two tanks.

Each container must be “reasonably sturdy and not fragile under normal conditions of use”, constructed to prevent the escape of vapors, not liable to deteriorate by contact with petrol, and clearly marked with the words “petrol” and “high”. combustible”.

Where should I store gasoline?

If you have petrol in cans or fuel cans, you are not allowed to store it in living quarters, so you cannot keep full petrol cans indoors.

However, the HSE states that petrol in jerry cans must be stored in a suitable building.

You can store them in a garage, shed, or other outbuilding as long as it’s well ventilated and there’s no ignition source nearby.

Since the start of the global health crisis earlier this year, the number of kilometers driven daily by car owners has fallen sharply.

For many, the daily trip to the office is no longer necessary. In addition, car trips to visit friends and family have drastically decreased. In short, this means cars are sitting in driveways longer than ever before without being driven.

So what happens to the gasoline in these vehicles when it stagnates for weeks or even months? How long can gasoline sit in a car before it goes bad?

Fuel Shelf Life How long the fuel remains usable in your petrol tank depends on the type of fuel. Regular gasoline has a shelf life of three to six months, while diesel can last up to a year before it starts to degrade. On the other hand, organic-based ethanol can lose its flammability in as little as one to three months through oxidation and evaporation. Tracking the age of the fuel in your tank can be a challenge. Its life begins in a refinery, where it may have been stored indefinitely before being transported. This period can range from a few days to a few weeks. Once it reaches a gas station, the fuel can again stall for a long time depending on the load on that particular gas station. It is possible that the petrol in your tank was over a month old when it was pumped out.

Recognizing Bad Fuel As gasoline ages, its chemical properties change. As a result, the engine cannot process the fuel properly. There are several signs that the gasoline in your car has gone bad. The simplest is your “Check Engine” light. If the car runs fine and the engine has oil, this light may have been triggered by gasoline not burning properly. Take your vehicle to a certified mechanic or dealer for an inspection. Another important indicator that the fuel has gone bad is when the car suffers from operational problems. This can be a failure to start, sluggish ignition, rough idling, or a loss of power while driving, especially when accelerating. The condition of gasoline can also be determined by its appearance and smell. Poor fuel looks darker or slushier. It also has a sour or unpleasant odor that is not typical of regular fuel. Some even describe the gasoline as smelling foul. In all these cases it is necessary to remove the bad fuel from the tank. Not only because the vehicle isn’t performing as it should, but also because bad fuel can damage internal engine components and create gummy residue that can cause clogs in the fuel line. Bad fuel, especially gas containing ethanol, can also draw in water vapor, which can corrode the tank and fuel system. Repairing the damage can be expensive if it has been parked for a longer period of time.

Gas. It’s all the rage these days, and for good reason. Prices are rising and there is no end in sight as far as I can tell.*

So let’s say you have an old driver that’s been gathering dust in your front yard, but it uses a little less fuel than your Toyota Sequoia (ha), so you want to drive it around more.

The problem is that you don’t know how long it’s been since you started it, so you want to get rid of the old gas in the gas tank.

*Note: I am not a resource economist. There could be an end in sight, or there could be no end. In any case, the prices have gone up now.

What exactly is “waste gas”?

In general, gasoline begins to break down and oxidize, which is the natural process that occurs when gas interacts with our atmosphere. This process can take 3-6 months for regular 85 octane gasoline and 2-3 months for high ethanol fuels.

As gasoline gets old it will start to smell “rotten”, look a little darker/muddy and can cause misfires as well as a higher chance of your fuel injectors (or even your fuel pump) becoming clogged, causing further problems for your engine in the long run Future.

You may notice a “stale” smell when you fill up your gas tank, or you may be able to see the gas appearing “semi-solid” through the transparent side of your portable gas canister. That means you have some old gas there and you should do something about it.

We’ll get into that later in this article, but you could either siphon off the bad gas and replace it with new gas.

Or, if you feel the gasoline hasn’t been in the tank too much longer than 6 months, you can fill up the rest of the tank in a process called “diluting”. This reduces the concentration of particles, so your fuel system is not put under as much strain – saving you headaches later.

I want to get down to the weed a bit to establish what REALLY is going on with old gasoline. So if you’re not that high or just not interested, feel free to read on. You may be wondering, “If crude oil can last millions of years underground, how is it that gasoline can spoil so quickly?”

Well, gasoline is a very different product from crude oil, which is extracted from under the surface of the earth. Gasoline is an extremely refined compound consisting essentially of a series of hydrogen and carbon atoms bonded together to form hydrocarbons. During the refining process, various impurities such as sulfur are removed to prevent environmental conditions such as “acid rain”.

In addition, the gasoline is then refined to the point set by the EPA so as not to pollute it as badly as it could be.

Why Does Gas Go Bad?

So why does gasoline go bad when it’s designed to such a high standard?

Well, the moment the gas comes into contact with air, the lighter hydrocarbons begin to vaporize, meaning the gasoline’s delicate balance breaks down and becomes less volatile. That means there won’t be as big a boom on each burn cycle.

Another interesting tidbit is that gasoline companies change the hydrocarbon content of their gas year-round to match atmospheric conditions.

For example, in winter there will be gasoline with lighter hydrocarbons, which are more easily ignited but more likely to vaporize. In winter, your gasoline needs to be easier to ignite so you can always start your car to get to your destination.

Conversely, in the summer, the hydrocarbons are heavier so they don’t evaporate as quickly, but they don’t need to be light since you’re not dealing with the same temperature difference as in the winter.

Furious! That’s a lot of knowledge, but cool stuff, right?

How to recognize old or bad gasoline

Try it. how does that smell If you LOVE the smell of gasoline seek help because you could end up in an episode of My Strange Addiction. If not, notice how the smell differs from the smell of brand new gas you get at a gas station.

Does the gasoline in your tank smell stale or “spoiled”? If so, but you know the gas hasn’t been sitting for much more than half a year, go ahead and top up the tank with fresh gas to dilute the bad stuff. Most modern engines are designed for different grades of fuel, so in this case, most likely, you will not do much harm.

If it’s your classic “baby” and you just don’t want to risk it, get a fuel siphon from your local auto parts store and siphon off the gas, baby.

Tip: Do not suck on the hose too much or you will get gas in your mouth. Ask me how I know.

Can you just throw it down the drain?

Do not do it. A gallon of gasoline down the drain can contaminate 250,000 gallons of drinking water, not to mention it’s very illegal in most countries so you can expect a hefty fine.

You wouldn’t throw batteries in the trash, would you? The same applies to petrol. Don’t throw gas in the trash at all costs.

This poses a fire hazard when walking down the garbage disposal line and could seriously injure someone responsible for the proper disposal and disposal of garbage.

If you’ve done this in the past, don’t worry as we’re all learning here. Next time, just make sure you dispose of it properly.

How to properly dispose of waste gas

You should not dispose of gasoline down the drain, toilet or trash can. But how to dispose of it?

#1 – Mix with new gas and use

First try to use it if it is not too old or contaminated. Dilute it with some fresh gasoline and use it in your weedwacker, lawnmower or other small engine that you care less about than your primary mode of transportation – your car.

#2 – Hazardous Waste Center

Next, if you just don’t want to deal with that, dispose of your gasoline using the resources provided by your local hazardous waste disposal center. Google “hazardous waste disposal near me” to find a location near you.

#3 – Community Hazardous Waste Collection Events

Many areas offer free hazardous waste collection on a regular basis, which also includes used gasoline. This is often done on an annual or quarterly basis, but some counties/cities/municipalities make this a monthly event. Check your local government’s website or call them to see if they offer some type of hazardous waste collection day in your area.

#4 – Contact your local fire department

You can also call the fire brigade emergency number for a recommendation on where/how to dispose of your old petrol.

#5 – Offer it to landscapers

If you notice a landscaping or lawn maintenance company working nearby, ask if they would like it. As already mentioned, used gas diluted with fresh gas usually works perfectly in lawn mowers and other small engine devices. They might be happy to take it off your hands.

#6 – Let it evaporate

While not the ideal method for safety reasons if you only have a small amount, it simply uncaps a container of gasoline to allow it to eventually evaporate. Better yet, put some gas in a wide, open container in a sunny spot. Never attempt this method in an enclosed space like your garage or shed.

Can you mix old gas with new gas?

Sure, this is actually a good bang for your buck if you have some old gasoline lying around and still want to use it. A good way to dilute old gasoline is to pour new gasoline into the same container to dilute any contaminants that might even be in there.

Keep in mind that modern engines with high pressure common rail (HPCR) systems only allow a certain amount of particulate matter through the fuel injectors. So if you have a newer engine, it’s best to be safe and simply dispose of the gasoline properly by calling your local hazardous waste center.

If you have an older engine with a lower pressure fuel rail system, by all means go for it. Just make sure you dilute that gas in the first place.

Also see: What happens when you put gasoline in a diesel engine?

Can you prevent gas from getting old?

Yes, in a way you can slow down the process. First, get your new gasoline in gasoline-specific containers. These allow enough airflow to not age the gasoline, but not enough for all of your gasoline to vaporize.

Then mix in some fuel stabilizer (STA-BIL is a good one). This will stabilize the compounds in your gasoline so it will last for years to come.

While this isn’t a permanent solution, your gas could last 2-3 years this way – as opposed to the 3-6 months it will take to go bad just sitting with no airflow and no fuel stabilizer.

Can old gas simply be vaporized?

In general, gasoline evaporates fairly quickly when the entire contents are exposed to air and allowed to oxidize. It leaves little to no residue and is fairly clean – surprisingly.

On the other hand, if you leave gas in a container with little or no exposure to air, it will polymerize into a putrid, brackish semi-solid that never evaporates.

Does a local auto parts store take old gasoline?

Auto parts stores like AutoZone, NAPA, and O’Reilly can take most old auto fluids, like motor oil and antifreeze, and dispose of them for you, but they won’t accept old gasoline.

Can old gasoline be rejuvenated?

To a certain extent, old gasoline can be rejuvenated as long as it is not contaminated with hard particles or has not sat for too long. The way to refresh old gas seems to be to dilute it by adding new gas to the mix.

Do you remember? “The enemy of pollution is dilution,” and the same concept applies to gasoline. Just get new gas from the gas station and put it in the gas tank you think is old. This should dilute the mixture to an acceptable level for your engine to run efficiently.

Well, if this is your car’s gas tank, bend down and sniff the gas intake. Does it even smell “stale”? If so, it would be wise to siphon off your gas and start with a clean slate. It’s not worth replacing your fuel injectors just to save a few bucks on the pump.

From powering vehicles and generators to gardening tools, gasoline moves our world. However, if you store unused fuel leftovers in your garage for too long, or sit in a riding lawn mower all winter, you risk it deteriorating or becoming contaminated during that time. At this point, you must treat it by legal disposal or by reusing it after dilution. Improperly and illegally disposed of gasoline – poured on land, down drains or down toilets – can result in fines, harm the landscape, kill animals, contaminate water sources and even pose a serious fire hazard.

How to dispose of gasoline

Check the appearance and smell of the gasoline to determine its suitability. If the older gas is not contaminated, dilute it with fresh fuel for reuse (optional). Find the nearest hazardous waste disposal in your area. Transfer gasoline to a state-approved container. Clean up spilled gasoline quickly and thoroughly. Transport gasoline to the disposal center.

Read on to learn how to dispose of gasoline safely and responsibly.

STEP 1: Check if the gasoline is old or contaminated.

To see if the gas is stale or contaminated, pour some of it into a glass container. Pour some fresh gasoline into another container for comparison.

If the gas in question is darker or smells more “sour” than the fresh gas, it has probably aged enough to lose potency. The addition of ethanol, which is a preservative, has made today’s gasoline more shelf stable than the fuel of years past. Still, gasoline stored for more than a few months (and before that an unknown amount of time in the gas station tank) deteriorates and loses flammability, which can ultimately affect its ability to fire your engine. While old gasoline won’t harm an engine, it will only make it run inefficiently or not fire at all. You can of course dispose of used gas, but you can also reuse it by diluting it with fresh gas (see step 2).

However, if the residual gasoline has rust particles, dirt, or discoloration, it may be contaminated. Do not reuse this fuel. Instead, proceed to Step 3 to dispose of it, as these particles can clog fuel lines and carburetors.

STEP 2: Use up old gasoline.

Old gas alone has lost some of the power that would have allowed it to fire an engine, but it is often safe to use up by diluting it with newer gasoline in the tank of a power tool or outdoor vehicle. Follow the right proportions and the old gasoline will reduce the combustibility of an entire tank of gas enough that it’s less of a concern.

If your lawnmower has only half a tank or less of old gasoline, topping up the rest with fresh gasoline can dilute it enough to fire the engine. You’ll burn through it pretty quickly if you’re working in your garden. You can choose to fill it up with more fresh gas mid-use to get a little extra oomph out of the fuel.

For larger amounts of gasoline, you can dilute it in the gas tank of your car or truck. First check your vehicle’s owner’s manual or search online for tank capacity, which ranges from 9 gallons to 16 gallons. For a small 9 or 10 gallon tank that the gauge says is at least 3/4 full, add a half gallon of old gasoline to the tank. Use a suitable “canister” (a gas jug with a spout) to slowly pour the old gas into the tank. Watch the gas level as you fill up and stop when the tank is just below the fuel filler cap safety flap. (This metal flap is pushed into the tank opening when you insert the nozzle; it’s designed to prevent gasoline from getting into the area between the tank opening and the gas cap, so you don’t get any nasty surprises when you take the cap off.) Similarly, you can use ¾ of a gallon of old gasoline into almost full 12 gallon tanks or a full gallon into 16 gallon tanks.

If you’re adding used gas to fresh gas in a vehicle, you can also ask employees at your local auto supply store if you can use fuel additives to increase the ratio of used to new gas in your tank to better use up the supply quickly — and if so yes, what additives they recommend. Injector cleaners often come in handy to use up old gasoline, depending on the particular engine and the type of fuel these professionals can assess. Check out CarBibles review of the best fuel injector cleaners if your mechanic recommends using such a product.

Of course you can dispose of used petrol. It is even advisable if the fuel is a particularly dark color compared to fresh gas, e.g. B. rusty brown or “milk chocolate” so you don’t risk sticking your engine with deposits or contaminants.

STEP 3: Find out where your nearest waste or contaminated gasoline disposal center is located.

Start with these four clues as to where to fill up near you, and be aware of when the center is open for visits. (Some are only open once a week or on certain weekends.)

Search online for “hazardous waste disposal center” in your county, city, or state.

Call your waste management authority and ask where the gasoline goes.

Check with your local fire department. Given the flammability of gasoline, they can often suggest how to handle the gasoline and where it should go.

Ask your auto repair shop if they would take the gas off your hands. Many won’t do this as it can incur a cost for them to take care of this on your behalf, but it’s worth asking if you already have a good relationship with a garage.

STEP 4: Transfer gasoline to a state-approved container.

Using a funnel, carefully transfer the old or contaminated gasoline from the existing container to a container specifically approved for gasoline storage, such as a B. a canister or a gas pitcher made of plastic. Many fire codes require each container to store less than five gallons. (You can pick up either at home and at car centers or gas stations.)

Pour slowly to avoid spattering, static build-up, or spills, and fill no more than 95 percent of the way to allow room for the fumes. Keep your face as far away from the spout as possible to minimize the amount you inhale. Close the container tightly with the lid immediately after pouring to prevent spilling or leakage.

advertisement

Place the container upright in a second container, e.g. B. a rubber cooler or garbage can, in case it should tip over and leak while driving. Wash your hands thoroughly afterwards if you get any splashes.

STEP 5: Treat spilled gasoline.

If stains get on your clothes, change your clothes and contact the stained kit. First you should blot off the excess with a white cloth. Cover the affected area with baking soda to absorb anything your cloth can’t; Leave it on for a few minutes and then brush it clean. Finally, rub liquid dish soap into the stain to treat it for five minutes before washing the clothing alone in the hottest water the fabric can handle. Line dry only long enough to be sure all traces of gasoline have been completely removed. Otherwise, remaining gasoline in the dryer can cause burns when exposed to heat.

If you have spilled gasoline on the driveway, soak up as much fuel as possible with an absorbent product such as a cleaning pad. B. cat litter on. It may take a few hours for the spilled liquid to be absorbed. Then sweep up the waste to dispose of with your liquid gasoline. You can get rid of any remaining stain with our driveway cleaning tips.

STEP 6: Transport gasoline to disposal center.

Drive carefully and never smoke in the vehicle while transporting gasoline. Fumes could linger or gas could have been sprayed on you, and it takes very little gasoline to be flammable in a small space with open flames.

Once you get to the disposal center you should be able to dump your gasoline into the storage container and take the empty 5 gallon jug home with you the next time you need to dispose of gasoline responsibly.

Safety tips when handling petrol

Gasoline is highly toxic and flammable, so use caution when transferring and disposing of the substance. Follow this and other advice from the US government’s Medline Plus.

advertisement

It is dangerous to inhale large amounts, so work outdoors if possible. If you can’t, get some fresh air quickly when you feel your lungs burn.

If you accidentally swallow gasoline, drink milk immediately and call the poison hotline at 1-800-222-1222.

If you get gasoline on your skin or in your eyes, flush with plenty of cold water for at least 15 minutes. See a doctor if it continues to burn or bother you after 15 minutes.

If the fuel tank has been kept full there should be no problem using the fuel. The biggest problem comes from ethanol in fuel, which absorbs water from the air. With a full tank of gas there is no real room for air, so little to no absorption takes place.

If the tank wasn’t quite as full as you thought (either completely dry or completely full is the best way to store a vehicle), there are products you can buy to help the fuel. As said in the other answer, it’s a good idea to put fresh fuel in the tank before running it too much. Cutting the fuel with fresh fuel will give you good results while safely getting rid of the old fuel. If there was only a 1/4 tank (or about that) without a fuel stabilizer, you’d want to drain the tank and run completely fresh gasoline in it. If you’re in a part of the world that doesn’t use an ethanol blend, you don’t have to worry. I’ve seen old fuel without ethanol that ran with no problems… And I’m talking old fuel here.

Fuel can stay good for a long time if it cannot absorb water. Fuel stabilizers can help if used before the vehicle is stationary, but little or nothing afterwards. When the fuel has absorbed water, there is a chance of corrosion and sediment that can clog fuel filters and injectors.

There are many reasons why you leave gasoline in your vehicle’s gas tank for long periods of time. Maybe you leave your car on vacation. Or maybe you have a luxury vehicle that you only drive every few months.

Whatever the case, you may be wondering how long gasoline can sit in a car. And if gas has a shelf life, how long does it last? Get these answers and more here.

How long does petrol last? It depends on

How long does gas last? How long can gasoline sit in a car? Gasoline can last anywhere from three months to three years depending on the type of gas and proper storage.

It’s important to note that while all gases naturally break down over time thanks to the action of oxygen (aka oxidation), not all gases are created equal. Most gasoline sold at a standard gas station can last up to three months, but other types of gasoline can last longer.

Learn more about the shelf life of three common types of gasoline below.

Pure Gasoline: Up to 6 months

Pure petroleum-based gasoline without ethanol typically lasts up to six months before it begins to rapidly degrade through oxidation. Pure gasoline does not absorb water like other types of gas, which means that this gas has an easier time avoiding moisture contamination.

Ethanol mixed gas: Up to 3 months

“Regular gas,” meaning most gasoline sold at gas stations across the country is ethanol-based gasoline, which is typically 90 percent petroleum and 10 percent ethanol. This type of gas has a shorter shelf life than straight gasoline, typically only lasting up to three months. Unlike pure gasoline, ethanol-based gas easily absorbs moisture, which can lead to contamination.

Unfortunately, it’s almost impossible to tell how old the gas is when you fill up your car at a gas station. Because from the time the petrol arrives at the gas station until you fill up your vehicle, it can be a few days or weeks old. By the time you pump your gas, the gas could have been at the gas station for over a month. So if you’re wondering how long gasoline can sit in a car, the answer is most likely up to three months from the time you filled up at a gas station.

Shelf Stable Gas: Up to 3 years

The type of gasoline with the longest shelf life is storage stable gas. Available online and at local hardware stores, fuel stabilizers are petroleum-based additives that can be added to gasoline before it is stored in your garage. Fuel stabilizers slow the oxidation of gas, making it last longer.

What happens if I put old gasoline in my car?

Now that you know how long gas lasts, what happens when you put old gas in your car?

The good news is that petrol can be a few days or a few weeks old, but thanks to the transport time of between six months and a year, it cannot damage your car’s engine. Still, it can affect the overall performance of your car and you may experience adverse effects like lower gas mileage than usual.

However, gasoline that is over a year old can cause things like engine knock, sputtering, and clogged injectors. It’s rare to buy gas from a gas station this old, but if you have old gas lying around in your garage that you want to use in your vehicle, we recommend properly disposing of the old gas instead.

How to recognize old gas

Wondering how to identify old gas? First of all, as gas ages, the chemical properties of the gas begin to change. If you have old gasoline in your car, the “Check Engine” light may come on. Old gasoline can burn improperly, which can trigger your check engine light.

In addition to the check engine light, your vehicle can also fail in other ways, such as: B. if it does not start, idles differently than usual and loses power while driving.

If the gasoline in question is not already in your car but is in a can, you can check if it is old by its smell. Old gasoline smells bad and has a slightly sour odor. It can also appear darker and thicker than “good” gas, appearing almost mud-like.
