In general, pure gas begins to degrade and lose its combustibility as a result of oxidation and evaporation in three to six months, if stored in a sealed and labeled metal or plastic container. Ethanol-gasoline blends have a shorter shelf life of two to three months.
-- Never store gasoline in any containers except those manufactured from sturdy steel sheeting which cannot easily be punctured. Glass containers and plastic containers used for food and milk are especially hazardous, as are rusted metal cans.
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.
Meanwhile, you can expect anywhere from three to six months with fuel that's been stored in jerry cans—in proper conditions. Motorcyclists and classic car enthusiasts will know that fuel stabilizers can boost the shelf life from anywhere between one to three years in optimal conditions.
Standard gasoline has a relatively short shelf-life. It starts degrading in a month, and most people avoid using gas once it's 6-12 months old. But if you add a fuel stabilizer, you can multiply the lifespan and keep gas stored for a few years.

How do you store gas for 5 years?
If you're going to store fuel like that, you need to keep that fuel safe, which means away from your home, your garage, and any sources of heat, sparks, or flame. A metal garden shed at least 50 feet from other structures is a good choice. You also need to consider heat from the sun and air as a threat.
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.
LPG shelf life is unlimited. The only limiting factor is the gas bottle itself. Assuming it is taken care of and not allowed to rust, it could last 20 years or more. Gas bottles typically need re-ispection every 10 years to refill the gas bottle but you can use it beyond 10 years, if safe to do so.
Gasoline can last between three months and three years depending on the type of gas and if it is properly stored. It's important to note while all gas will naturally begin to degrade over time thanks to exposure to oxygen (also known as oxidation), all gas is not created equal.
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.
The gas that can be mixed with new gas can only be three to six months old. If it has been stored for more than six months, there are some solid chances that it has gone bad.
Corrosion resistant – unlike metal gas cans, plastic gas cans won't rust or corrode over time due to the elements. Won't rupture – metal gas cans explode when exposed to extreme heat. Plastic gas cans will melt rather than create a dangerous explosion.
Store gas cans at room temperature and far from flames or sparks. Make sure children and pets don't go near gas cans. Check containers once a month for potential leaks. Add fuel stabilizer if gas cans have been full longer than 30 days.
Gasoline keeps longer if it is stored in a cool place and the container is kept almost 95 percent full. However, leave some headroom for gasoline to expand if it warms up in storage.
Each 220g of butane, more or less, will last about 3 to 4 hours on low heat, meaning you can really get your money's worth with this type of gas. One of our Calor gas butane 15kg bottles could last, therefore, approximately, 238 hours on low heat.
In general, gasoline and diesel can be stored for 6 months to 1 year without significant degradation if they are stored in a clean, sealed, and dry container or tank, away from sunlight, heat, and sources of ignition.
You should aim to use your gas canister within 20 years just to be on the safe side as valves and connections will fail long before the fuel goes bad. Larger gas canisters are designed to be used outdoors and often stay in the exchange rotation for over 10 years while being inspected every time it is refilled.
Gasoline has a shelf life of just 3 to 6 months. Over time, bad gas can gum up your mower's engine. Siphon out the old fuel from the tank to get rid of bad gas.
The best way to make old gas usable is to dilute it with new gas. Simply fill your car's fuel tank or a storage tank with 3 gallons (11 l) of fresh gas for every 1 gallon (3 l) of old gas you pour in. Then, gently rock your car or shake the storage tank to mix the gas together.
If you store any fuel in the garage, do so only in dedicated, leak-proof containers out of the reach of children and out of the paws of pets and away from potential sources of fire ignition such as water heaters or power tools. A shed away from your home is a better storage spot.
Like a wine without a cork, gas can go bad when it sits around mingling with air. Fuel actually starts to turn nasty after 30 days. Since your car's fuel system is not an airtight container, precautions have to be taken for long-term storage. The easy solution is an additive called a fuel stabilizer.
For long-term fuel storage, metal cans are better than plastic. Plastic chemicals can leach into fuel, and plastic will degrade over time. Metal can rust, but in general will last longer than plastic. Check local and state laws about fuel storage.
The storage life of petrol is one year when stored under shelter in a sealed container. Once a seal is broken the fuel has a storage life of six months at 20°C or three months at 30°C. The storage life of petrol in equipment fuel tanks is one month.
