![]() ![]() Expect non-ethanol gas to last at least 6 months if it’s properly stored. Petroleum-based gasoline that does not contain ethanol will still succumb to oxidation and volatile compound evaporation in a sealed container or tank, but these processes usually occur more slowly in pure gasoline. Pure gasoline keeps for at least 6 months. Generally, the higher the ethanol content in the gas, the shorter its shelf life, so E15 (15 percent ethanol content), E20 (20 percent ethanol), or E85 (85 percent ethanol) gas will expire sooner than E10 gas will. Because ethanol is hydrophilic (aka, water-loving), it will also readily absorb any water or humidity in a sealed container resulting from condensation, causing both moisture contamination of the fuel and the eventual separation of the fuel into distinct gas and ethanol layers. The shelf life of gas that is ethanol-blended is usually about 3 months maximum because ethanol oxidizes pretty quickly. is E10 gas made of 90 percent petroleum-based gas and 10 percent ethanol (ethyl alcohol). ![]() Energy Information Administration, most gasoline sold in the U.S. ![]() Ethanol-blended gas lasts up to 3 months.Īccording to the U.S. Factors that can shorten or lengthen gasoline’s life include how pure the gas is and whether it has been treated with a fuel stabilizer. Though it naturally degrades and loses combustibility over time due to oxidation and evaporation of its volatile compounds, gasoline usually lasts 3 to 6 months when properly stored in a tightly sealed gas can or metal tank that’s within the capacity limits recommended by your local fire department (usually no more than 5 gallons). Properly stored gasoline can last up to half a year. Read on to learn how long gas lasts in a container, along with tips on spotting and disposing of stale gas. But “old” gas is not necessarily “bad” gas-in other words, old isn’t the same as contaminated. Filling engines with gas that has been in storage for longer than that amount of time indicated could void the product warranty. Indeed, before using any stored gas in a mower, tractor, or other machinery, first check the fuel storage time limits laid out in the manufacturer’s guidelines for that piece of equipment. You’re wise to wonder about the shelf life of stored gasoline, because once gas loses its engine-igniting ability it could damage fuel system components. ![]()
