In short – definitely, gasoline has an expiration date. However, when it comes to specific numbers, the information appears vague and not easily explained. Factors such as the material of the fuel storage container and the octane number are considered. Therefore, to determine whether gasoline has an expiration date, it is necessary to consult experts and quality certificates.
Representatives of gas stations claim that the shelf life of gasoline depends on the quality of the fuel itself. Gasoline obtained at the oil refinery, without the use of additives and supplements, has a higher chance of not spoiling. Low-quality fuel, artificially boosted with octane enhancers, has a limited shelf life.
Does gasoline have an expiration date
In terms of storage duration, gasoline in a car’s tank will not lose its properties within half a year. In a metal canister, in a static state, fuel can be stored for a year. Using plastic containers for storage is prohibited, but professionals allow such use and set a shelf life of 6 months. In specialized tanks designed for gasoline, fuel is stored for 3-5 years.
However, petrochemical engineers, when asked whether gasoline has an expiration date, state that in metal cans, high-octane gasoline (above 92) will not lose its properties over 5-8 years. Notably, sediment formation during long-term storage does not spoil the fuel and does not reduce the octane number. Engineers immediately clarify that this applies to gasoline supplied from the oil refinery.
