- Tips To Avoid Gasoline Breaking Down During Storage
Gasoline Breaking Down During Storage?
Modern gasoline formulations tend to breakdown while in storage, sometimes starting in as little as 6 weeks. Years ago, you could store a car and have gasoline be fine for years as long as it didn't get water in it or evaporate. Additives (many blame the ethanol) in these new fuels can cause swelling in rubber parts like fuel lines, and break down parts like fuel pump diaphragms, o-rings, gaskets, and carburetor floats and seals. We recently saw an original'57 Chevrolet show car have its carburetor opened to reveal the accelerator pumps had been completely dissolved by the modern fuels.
Draining your gas tank for winter storage may be impractical for many cars and owners, and can allow the inside of the tank to rust. A product Eastwood sells called Sta-Bil® stabilizes your fuel for short-term storage. Just a small amount in your gas protects against phase separation and deterioration, as well as gum, varnish, rust and corrosion, and water in the fuel. This product can also be bought at lawn and garden stores, tractor dealerships, boat yards and even some private airports...any place gasoline engine vehicles are frequently stored.
Eastwood also has several Fuel Guard Additive products of their own to combat this problem. The first is meant for regular use in your daily driver - Daily Driver Formula Additive (item #12735Z), and the other for adding to the tank before storage - Gas Storage Stabilizer Additive (item #12736Z). Either will help protect your classic, or even more modern car, boat or motorcycle from the effects of ethanol and other chemicals in modern fuel. You can even use them in lawn and garden equipment, or anything powered by gasoline really.
