FR
Sunoco® FR™ is an unleaded oxygenated race fuel that performs well in turbocharged engines as well as air-restricted naturally aspirated engines that can benefit from an oxygenated racing fuel. It complies with certain race fuel regulations limiting oxygen to 4 volume percent.
Sunoco FR contains additives to enhance storage life. Sunoco FR will not harm oxygen sensors and can be used in any racing application requiring an unleaded fuel. As with any gasoline, FR should be stored in opaque sealed containers where temperatures are stable.
