Sunoco® Supreme™ is a 112 octane leaded race fuel designed for competition engines routinely operating over 7000 rpm. Supreme is blended to achieve a high motor octane number and fast burn speed to ensure engine protection lap after lap and pass after pass. It features a comprehensive additive package to enhance shelf life by improving storage stability and minimizing oxidation. Sunoco Supreme is designed for compression ratios up to about 15:1 in small block V8s, and can tolerate higher compression ratios in smaller or more efficient combustion chambers. Supreme’s fast burn speed also makes it a popular choice for 2-stroke applications.
As with any gasoline, Sunoco Supreme 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 3 years.
