How do fuel stabilizers work? They work to chemically slow down the oxidation process, break down water into dispersed droplets or bond with the absorbed water to form a flammable product. Some also work to prevent ice buildup during the winter months.
When should you use gas stabilizer?
When your engine is in long-term storage, it is important to use a fuel stabilizer. STA-BIL® Storage is formulated to protect the fuel from deteriorating for up to 24 months, meaning that the fuel will remain at full strength and not varnish or gum up the internals of your engine.
How long does gasoline last with stabilizer?
Fuel stabilizers keep fuel fresh and effective for at least two years of storage time. Chemical reactions within stored fuel, plus the evaporation of some volatile components, can leave liquid fuels less likely to ignite properly in an engine after more than three months of storage.
Is gasoline stabilizer necessary?
For everyday life, fuel stabilizers aren’t necessary. When a vehicle is driven or used, the gasoline burns up before it begins to evaporate and degrade. For people who own seasonal equipment, classic cars, or boats that tend to sit for more than three weeks at a time, however, fuel stabilizer is a fantastic idea.
Can I put gas with stabilizer in my car?
Make sure you put the stabilizer in right before you add fuel so that it mixes in properly with the gasoline, he says. Also, moisture can get into the tank over time because gas tanks sweat, and moisture will cause the gasoline to break down even quicker, says Brannon from AAA.

Adding stabilizer to the gas tank is not the correct way to do it. Most stabilizer manufacturers tell you how much to mix into fairly large quantities, like 1 ounce to 2.5 gallons. Any more than that and you dilute the gasoline so much you’re likely to get detonation and a loss of power.
Is 2 year old gasoline still good?
How old is too old for gas? … 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. Bad gas can be drained from the tank to prevent damage to the engine.
Should I add stabilizer to ethanol free gas?
Adding a stabilizer to the fuel can extend its shelf life to up to 2 years. Ethanol-free fuel doesn’t suffer from the moisture issues that pump gas does so it is unlikely that you’ll benefit from adding stabilizer unless you are storing it for more than six months.
Will fuel stabilizer help old gas?
Everyone advises that you should add a stabilizer to gas as soon as you purchase gasoline. They are all adamant that no additive will restore old gasoline. The best you can hope for is that adding a stabilizer to old gas will stop any further degradation. … Gasoline is considered a petroleum distillate, as is kerosene.
How can you tell if gasoline is bad?
