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.
Is 2 year old gasoline still good?
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.
Can gasoline be stored long term?
It’s generally accepted that stored fuel should be used within six months to a year. You can extend that a bit with additives, but it’s a good rule of thumb to cycle through your fuel at least every six months for maximum quality.
How long is gasoline good for in a can?
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.
How do you tell if gas is bad?
Bad fuel will have a darker or muddier appearance. It will also have a sour or disagreeable odor not typical of normal fuel. Some may even describe the gasoline as smelling spoiled. In all these cases, it is necessary to remove the bad fuel from the tank.

Does gas go bad?
“Gas can start to go bad in as little as just three months because the lighter, more volatile components of gasoline evaporate over time,” says John Ibbotson, Consumer Reports’ chief automotive services manager at the Auto Test Center. Using old fuel in your car can sap engine power, causing hesitation and stalling.
Are metal gas cans better than plastic?
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.
Can Old gas ruin an engine?
Old gas does not become contaminated necessarily, but rather loses its combustible properties and volatile compounds. When you use gasoline that’s too old, it can damage internal engine components. It may also start to form a gum residue that could cause blockages.
Can bad gas ruin an engine?
Older gas can cause engine problems, such as engine knocking, sputtering, and clogged injectors, if it is not properly cooled. In order to prevent engine damage, bad gas can be drained from the tank. One caveat to keep in mind is that you cannot tell how old the gas is when you first pump it into the car.
What is considered old gasoline?
