Diesel, Gas, Upper Cylinder, Injector Clean, Anti-icing, Fuel Stabilizer, Cetane Boost, Octane Boost

Additives for diesel and gasoline fuels; increase your gasoline octane, fight the effects of ethanol, or merely clean your fuel system of power robbing build-up and pass that state mandated emissions inspection. There's also an additive to preserve your gas when it's time to store your snowmobile or jetski for the season.

If your motorcycle needs a little TLC then consider the motorcycle octane boost and quick shot gas additives.

For diesel owners, whether it's a Cummins, Duramax, Power Stroke, Mercedes, Detroit, Volvo, or Mack there's diesel injector clean for restoring spray patterns, diesel cold flow for lowering the gel point of your fuel, diesel recovery for thawing a frozen fuel filter, and cetane boost for kicking up the cetane.
