Sunoco® 260 GTX™ is an unleaded racing fuel that contains no oxygenates and no metallic additives. 260 GTX is a good fuel for many applications that need more detonation protection than typical street gas provides, yet cannot use a leaded fuel. It has been shown to produce repeatable power levels in small block V8 engines to 12:1 compression ratio, and will tolerate more compression in engines with smaller or more efficient combustion chambers. Turbocharged and supercharged race cars that require an unleaded fuel are good candidates for Sunoco 260 GTX.
