Standard

Sunoco® Standard™ is a 110 octane leaded race fuel that is used in many forms of motorsports.  Sunoco Standard is designed for compression ratios up to about 13:1 in conventional V8 engines with iron cylinder heads.  It can tolerate higher compression ratios in smaller or more efficient combustion chambers.  While most racers use Sunoco Standard in naturally aspirated applications, it is also a good choice for mild nitrous, turbocharged, and supercharged applications.

Sunoco Standard features a comprehensive additive package to enhance shelf life by improving 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 Sunoco Standard is in excess of 2 years.
