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.
