Fuel Conditioner Q & A

Treatment Levels of STA-BIL®
The treat level of the 4 oz. STA-BIL® in a can differs from the treat level for all the other available sizes. This is because two different formulations or concentrations are used:
A 4 oz. can of STA-BIL® treats 5 gallons of fuel. Using the 4 oz. size, 1 ounce of STA-BIL® treats 1 ¼ gallons of fuel. New 4 oz. bottles of STA-BIL® will have a more concentrated formula (1 oz. will treat 2 ½ gallons) All other available sizes of STA-BIL® cans or bottles are more concentrated whereby 1 oz. of STA-BIL® treats 2 ½ gallons of fuel. One more thing, don’t be concerned about over treating your fuel….pouring a little extra STA-BIL® into your gas will have the same results as a "perfectly measured" application. A little extra STA-BIL® will not harm your engine or fuel system.

Storage/Shelf Life of STA-BIL®
STA-BIL® will stabilize fresh fuel and protect an engine’s fuel system up to 15 months when used as directed. For best results, treat fresh fuel promptly when purchased. The STA-BIL® can or bottle itself has a shelf life of 2 years. STA-BIL® that is discolored and has turned dark brown is an indication that it is time to replace your old STA-BIL® with a new bottle or can in order to insure best results.

Application & How STA-BIL® Works
Using STA-BIL® in all types of power equipment when the fuel is still fresh is an inexpensive and effective way to protect engines and treat your gas for quick starts next season. STA-BIL® contains proprietary additives designed to reduce oxidation and metal corrosion of gasoline and diesel fuels. These additives prevent the fuel from oxidizing which can cause the build up of gum and varnish in your fuel system. In simpler terms, STA-BIL® surrounds "good" fuel molecules with a coating so that oxygen can not "break down" the fuel molecules into "bad" gum and varnish. Make sure you run the engine for a few minutes after adding STA-BIL® so that it can work its way through the entire fuel system.

What Happens to Fuel When it is Stored?
Stored fuel can break down to form gum and varnish deposits which clog your fuel system and make gas go bad. This can cause bad starting problems, increase maintenance costs and shorten the life of small engines.

Any fuel, be it gasoline, diesel, or heating fuel, is made up of many different organic compounds. These compounds are constantly changing over time and become new compounds that change the characteristics of fuel. Oxygen and other elements in the environment create new molecules that build up to form gummy residues or varnish-like films that can clog fuel lines, carburetors, and injectors.

Some fuels are treated with oxidation inhibitors that allow them to be stored up to two months without generating excessive deposits. Other fuels have no inhibitors at all. In any case, proper storage of equipment includes stabilizing the fuel to protect your engine.

Is Draining Fuel A Good Solution?
Not really. Draining fuel can be a hassle that leads to other problems. First, it is impossible to get every drop of fuel out of the system by simply draining. In order to remove all fuel, lines must be blown out, or enough fuel will remain to cause problems. Second, draining exposes the bare metal in the tank and fuel system to air and moisture which causes rust and corrosion. Third, gaskets and seals may dry out or crack, leading to leaks when the system is refilled. Lastly, drained fuel is a fire and safety hazard and proper disposal is difficult. For these reasons, draining is not the solution.

Can Fuel Stored in a Gas Can or Tank Cause Problems?

Yes. Fuel stored in gas cans or tanks also gets old, oxidizes and breaks down. You might be left with bad gas. Using the same fuel next season greatly increases the likelihood that deposits will form in your equipment's fuel system. Prevent this problem - stored fuel should be stabilized too.

What Does STA-BIL® Do?
STA-BIL® keeps gas fresh for quick starts. It's a blend of scientific additives which prevents fuel from undergoing degradation and oxidation during prolonged storage. STA-BIL acts as a protective wrapper around fuel molecules so they don't combine with oxygen to make your gas go stale. Fuel stabilized with STA-BIL stays fresh and will perform as though it had just been pumped from the refinery pipeline.

How Well Does STA-BIL® Work?
It works great. On average, the life of your typical gasoline is extended from 2 months oxidation life without STA-BIL® up to 15 months with STA-BIL.
STA-BIL keeps your gas fresh for quick starts.

Who Recommends STA-BIL®?
70 leading engine and equipment manufacturers recommend STA-BIL® to keep gas fresh. Millions of homeowners have made STA-BIL the #1 dominant stabilizer for gas in gas cans and power equipment.

What Kind of Equipment Needs STA-BIL®?
Any equipment that's not used often, or stored for 60 days or more, needs STA-BIL®. This includes all 2-cycle or 4-cycle engines like lawn mowers, tractors, marine engines, jet skis, snow throwers, snowmobiles, motorcycles, chainsaws, ATV's, RV's, generators, pumps, golf carts, automobiles, trucks, garden tillers, lawn edgers, farm equipment, mini-bikes, motor scooters, you name it. If it has a gas powered engine, it needs STA-BIL. You should also use Fogging Oil to protect your engine's combustion chamber during storage.

Is STA-BIL® Easy to Use?
Yes. Just add STA-BIL® to the fuel according to the directions on the bottle. For best results, treat fresh fuel promptly when purchased. Pour STA-BIL into your gas can and agitate the fuel for a good mixture. Prior to storage, add STA-BIL to your equipment and run it for 5 minutes to treat the entire fuel system. Next season, the engine will start easily and run smoothly.
