Avgas is a high-octane fuel used for aircraft and, in the past, racing cars. Avgas is a portmanteau for aviation gasoline, as distinguished from mogas (motor gasoline), which is the everyday gasoline used in cars. Avgas is used in aircraft that use piston or Wankel engines; gas turbines can operate on avgas, but typically do not. Turbine and diesel engines are designed to use kerosene-based jet fuel.

JET A and JET B additives:

• Antioxidants to prevent gumming, usually based on alkylated phenols, eg. AO-30, AO-31, or AO-37;
• Antistatic agents, to dissipate static electricity and prevent sparking; Stadis 450, with dinonylnaphthylsulfonic acid (DINNSA) as the active ingredient, is an example
• Corrosion inhibitors, e.g. DCI-4A used for civilian and military fuels, and DCI-6A used for military fuels;
• Fuel System Icing Inhibitor (FSII) agents, e.g. Di-EGME; FSII is often mixed at the point-of-sale so that users with heated fuel lines do not have to pay the extra expense;
