How long can you keep diesel in a plastic container?
Plastic drums can safely store diesel fuel for up to six months.
As for diesel, it can remain usable for between six and 12 months before becoming 'gummy' which, if used, can clog up filters and cause you issues with your engine.
According to OSHA, a business must store inflammable liquids such as diesel fuel in appropriate containers that are secure and away from other hazards. The containers can be made of metal, plastic or glass and must remain away from other sources of heat or areas that can accumulate fumes.
Though it naturally degrades and loses combustibility over time due to oxidation (exposure to oxygen) and evaporation of its volatile compounds, gasoline usually lasts three to six months when properly stored in a labeled, tightly sealed plastic container or metal tank of the capacity recommended by your fire ...
The ideal conditions for storing diesel fuel include keeping fuel dry and at a cool temperature (below 70 degrees Fahrenheit). Such conditions ensure storage life between six to twelve months. To extend fuel life beyond twelve months, fuel stabilizers are required.
It's not a substance that can readily be stored for a long time without being chemically treated. While you might think plastic drums make a good storage container, most plastic drums can't be used to store fuel.
' In reality, there is no expiration date on diesel per se, but the performance of your diesel fuel is affected the longer you store it. In fact, storing diesel without properly treating it can lead to all kinds of issues, not only for the fuelitself, but for any vehicle you decide to put the fuel in later.
Diesel fuel storage tanks
For larger amounts, you need to have special storage containers, such as 55 gallon drums or a stand-alone tank. Larger diesel tanks, made of metal or specially formulated polyethylene, can be installed above ground or below ground, depending on the site and local regulations.
Well, without diesel fuel additives, diesel can go bad in as little as 30 days before this oxidization process becomes unwieldy, creating deposits that can damage fuel injectors, fuel lines, and other system components which will hurt fuel economy and performance.
This means the diesel fuel will prematurely ignite in the diesel engine, which can lead to engine damage. Gasoline contamination can also damage the fuel pump and mess up diesel injectors. This happens because of a drop in lubrication. Simply speaking, gasoline is a solvent while diesel is an oil.
Can you use 2 year old gas?
Degradation occurs from the get-go but most gas stays fresh for a month or two without issue. However, gas that is more than two month old is generally OK to use with only minor decreases in performance. Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors.
Keep your fuel tanks stored in a garage or shed, in a well-ventilated area. Be sure your tanks are not in direct sunlight, and keep them away from any other sources of heat, such as space heaters and your vehicles' exhaust pipes. Periodically, inspect your storage tanks for pressurization.

Plastic drums are a popular storage medium for all kinds of preparedness necessities. So, you might wonder: Can you store fuel in a plastic drum? The short answer is that no, you shouldn't store gasoline or any other fuel in a plastic drum.
- Gelling or sludge.
- Darker color.
- Sediment.
- Fuel filters clogged frequently.
- Poor fuel efficiency.
- Damaged fuel pumps.
- Harder to start machine.
- Black smoke.
The best solution to the problem of old diesel fuel is to have the tanks cleaned and fuel polished ever three years. This is done by using a remote filter and fuel pump to remove the sludge and water. This can be expensive due to the amount of time and equipment it takes to do this task.
In general, diesel will last in a portable can for between six and 12 months before it begins to degrade. Like petrol, however, how it is stored can affect its longevity.
5. Never put or keep petrol in unsuitable containers. Some plastic containers will dissolve when petrol is put in them. Always use secure metal or approved plastic containers which are properly marked.
Which fuels have the longest shelf life? Propane, alcohol, wood, and charcoal are examples of good emergency storage fuels that can be stored indefinitely and still remain viable.
How Long Does Diesel Fuel Last? Studies have determined within 28 days of storage diesel fuel #2 begins to become contaminated and start to degrade. Diesel fuel can only be stored from 6 to 12 months on average — sometimes longer under the best conditions.
Diesel, like petrol, is a fuel that can expire. It's important to store diesel fuel in a container designed to block out heat, water and air, which can speed up the expiry process. Under the right conditions, diesel can last up to twelve months, but by adding a diesel fuel stabiliser, you can make it last even longer.
How much diesel can you legally store?
A person keeping over 30 litres and less than 275 litres must notify the authority in writing with the name of the occupier, address of the premises and confirmation that the petrol is stored in accordance with regulations – not licenced. A person keeping in excess of 275 litres will require a licence.
Guidance. A small quantity of diesel can be put in the oil container at a north London reuse and recycling centre (RRC). If you need to dispose of more than 5 litres you will need to use the free City of London Hazardous Waste Service (opens in a new window).
Storing petrol and diesel at home is certainly safe, as long as you follow the storage guidelines and regulations in place: Do not store it in living areas. Keep it in a well ventilated building, away from sources of ignition. Do not leave it outside.
Plastic drums can safely store diesel fuel for up to six months.
I put diesel into a gas can a few months back in a pinch, but the nozzle for the pump didn't fit down into the fill hole....had to use my hand as a gasket (NOT recommended!) In a pinch it works, but its best to have a yellow can for diesel, and a red can for gas if you can manage it.
It won't be a problem whether it is a steel or plastic Jerry providing that is for fuel in the first place and in good condition. Empty the can and fill with diesel. Any residue of petrol will not be an issue.
Old and new gas should not be mixed for a variety of reasons, the major ones are; The old gas degrades over time it should not be added because it has already lost it's combustibility. It can cause sputtering. It might fail to fire it up.
The tires can go flat.
But when a car is left to sit, they can become warped, flat and deflated. Definitely check your tires' air pressure before you resume driving. Bubbles may even appear in the tire and could cause a blowout while driving at high speeds.
A The short answer is no. All gas in California contains 10 percent ethanol and while this does not harm cars, ethanol can damage some small engines — especially older ones — in lawn mowers, chain saws, outboard boats, etc.
Regular gasoline has a shelf life of three to six months, while diesel can last up to a year before it begins to degrade. On the other hand, organic-based Ethanol can lose its combustibility in just one to three months due to oxidation and evaporation.
How do you store fuel at home?
Keep gasoline containers tightly closed and handle them gently to avoid spills. Gasoline is a flammable liquid and should be stored at room temperature, away from potential heat sources such as the sun, a hot water heater, space heater or a furnace, and a least 50 feet away from ignition sources, such as pilot lights.
You can use too much fuel stabilizer in your lawn mower, but the results are normally not dire and in some cases not noticeable. It can clog carburetors and cause corrosion over extended periods of time, but over adding fuel stabilizer normally will just waste stabilizer.
The best containers for handling gasoline are Underwriters Laboratories (UL) or Factory Mutual (FM) approved safety cans (see Figure 1). Safety cans are available in several sizes and have various mechanisms for opening the valve to pour the liquids. Funnel spouts can be added to make pouring easier and reduce spills.
A sturdy plastic like high-density polyethylene (HDPE) is commonly used to make plastic gas cans and barrels because it insulates its contents, and shields gas from the heat of its environment.
- Gelling or sludge.
- Darker color.
- Sediment.
- Fuel filters clogged frequently.
- Poor fuel efficiency.
- Damaged fuel pumps.
- Harder to start machine.
- Black smoke.
When stored under cover in sealed containers it will usually last for one year but it can last longer. The main problem with diesel fuel in opened containers is that moisture from condensation will create a favorable environment for fungus and bacteria that degrade the fuel.
