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.
How can you tell if gasoline has gone bad?
If it has a rough idle, stalls frequently during acceleration, or fails to start at all, your gas has gone bad. Sometimes, bad gasoline will also cause the check engine light to illuminate. You can also tell if gasoline is bad by its appearance. If it’s darker than usual or has a sour smell, it’s probably bad.
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.
How long can gas be stored?
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.
Is it OK to mix old gas with new gas?
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.
How do you treat old gas?
Adding fuel additives to old gas can help protect your vehicle’s engine from harmful effects.

How long can gas sit until it goes bad?
The Shelf Life of Fuel
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 5 year old gas still good?
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
Can I use 6 month old gas in my mower?
Pure gasoline can stay ok in the tank for as long as 6 months. Gasoline with ethanol goes bad earlier because of ethanol’s oxidizing tendency. Ethanol blended gasoline can last in the tank for up to 3 months. Stabilizers can be added to gasoline to extend its shelf life.
Which fuel lasts the longest?
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.
