Sunoco Racing Fuel EX02
Sunoco EXO2’s high oxygen content – up to five times as much as pump gas – can be beneficial in crate engines, two-barrel engines, and racing classes with cylinder head limitations, as well as engines running at higher altitudes. Due to its high oxygen content, EXO2 requires a richer air/fuel mixture. Using EXO2 without proper air/fuel mixture changes may make your engine run too lean. Please consult the stoichiometric air/fuel ratio data in the Technical Details section below.
Since non-oxygenated race fuels typically have a stoichiometric air/fuel ratio of 14.6:1 to 15.1:1, you are likely to have to increase the fuelling by 10 to 15 % depending on the fuel you are currently using. We advise storing EXO2 in opaque, tightly sealed containers and kept where temperatures are stable. Remove drum pumps immediately after use and reseal the drum. Properly stored, the shelf life of Sunoco EXO2 is between one and two years.
Note: Sunoco EXO2’s octane values has been estimated because of the extreme oxygenation of this fuel. The octane RON value of 115 is a conservative estimate
