Supreme

Sunoco® Supreme™ is a 112 octane leaded race fuel designed for competition engines routinely operating over 7000 rpm. Supreme has a high motor octane number and a fast burn speed to ensure engine protection lap after lap and pass after pass. It is designed for compression ratios up to about 15:1 in small block V8 race engines and can withstand higher compression ratios in smaller or more efficient combustion chambers. Supreme’s fast burn speed also makes it a popular choice for 2-stroke race engines.

Sunoco Supreme features a comprehensive additive package to enhance shelf life by improving storage stability and minimizing oxidation. It should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of Supreme is in excess of 2 years.
