Pure Gas Now Available

Pure gas should be used in all your small engine and outboard motor applications. Three problems Ethanol can cause:

It is a Water Magnet - It will pull water out of the air right through your gas tank vent hose. In our high-humidity climate this can be especially harmful to your engine. As moisture is absorbed, the molecules of alcohol/water become heavier than the gasoline in the tank, and they settle at the bottom. This process is called "phase separation".

Unstable Octane Levels - Due to ethanol's high octane rating, if enough water is present in a fuel tank the ethanol can migrate to the water layer, dropping the octane level. This will leave you with lower octane fuel in the tank, and if the separated mixture becomes great enough to reach the fuel pickup tube, it will be sucked up into the engine, where it can clog filters, carburetor jets and fuel injectors.

Solvent Properties - If there is any gum or varnish build up in your tank, the alcohol will dissolve these deposits, and they will be sucked into the engine fuel system. If that weren't bad enough, the alcohol and water combination mentioned in #2 may also encourage the growth of bacteria in the fuel tank which turns into sludge and damages the fuel system.
