Gasoline has a shelf-life. Within a few months, untreated gas fades in potency and can gum up the internals of the fuel system. Within 6 months, stored fuel can completely varnish the carburetor, requiring cleaning in order to get the engine running again. 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. This eliminates the need to drain your fuel before storing the engine. It also protects ethanol blends as well.
The shelf life of STA-BIL® is 2 years after it has been opened. If the color of the liquid turns very dark red or brown, it should be replaced as the effectiveness has been lost.
Using STA-BIL® fuel stabilizer is easy, simply pour it into the gas tank and then run the engine for a few minutes to distribute the treated fuel into the rest if the fuel system. Your engine will remain fresh for up to 24 months with one treatment of STA-BIL® Storage.
The bottle is unique to STA-BIL® fuel stabilizer, as you might notice. There are two spouts, one is normal, and one is long and skinny. This is the measurement spout. Uncap the spout, squeeze the bottle until the fluid reaches the line you need, and then pour out that metered dose. STA-BIL® should be added at 1-ounce per 2.5 gallons of fuel for proper protection.
With your fuel properly treated, you can rest assured that your engine will start up when you need it, even after a long hard winter. Whether you are storing a lawnmower, motorcycle, snowmobile, classic car, or generator, STA-BIL® will ensure the fuel stays at full strength.
