Sunoco 260 GTX

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.

260 GTX is not a street legal fuel and is for off-road and racing use only.  However, it will not harm sensors such as oxygen sensors used in fuel injection systems.  It is also an excellent choice where oxygenates such as alcohols and ethers are limited or banned by the race engine manufacturer or race sanctioning organization.

Sunoco 260 GTX contains additives to enhance shelf life and engine cleanliness.  However, as with any gasoline, it should be stored in opaque, tightly sealed containers where the temperature is stable.  Handled under such conditions, the shelf life of 260 GTX is in excess of 2 years.
