Sunoco EXO2 107 Octane leaded racing fuel is a highly Oxygenated fuel which is about 3 times more than you see at the pump. 

Sunoco EXO2 Race Fuel can be very beneficial to your performance in Crate Engines, Two-Barrel intakes and race classes limiting the cylinder head size. Due to its higher oxygen content, it is necessary to create a richer air fuel mixture anywhere from 10% to 15%. 

As with any gasoline, Sunoco EXO2 Race Fuel should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Drum pumps should be removed immediately after use. Properly stored, the shelf life of Sunoco EXO2 is one to two years. 

Note: EXO2’s octane values must be estimated because of the extreme oxygenation of this fuel. The (R+M)/2 octane value of 110 is a conservative estimate.
