260 GT Plus

Sunoco 260 GT Plus is a high octane, highly oxygenated unleaded race fuel.  It is our highest octane unleaded race fuel which makes it a popular choice for racers looking for high octane in an unleaded product.

Because 260 GT Plus contains more oxygen than is allowed in pump gas, it is for off-road and racing use only.  However, it will not harm oxygen sensors.  Due to its high oxygen content, an increase in fuel flow is required to utilize the full potential of 260 GT Plus compared to conventional non-oxygenated fuels.

Sunoco 260 GT Plus contains additives to enhance shelf life and promote engine cleanliness.  As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable.  Properly stored, the shelf life of 260 GT Plus is in excess of 1 year.

Note:  exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided.

Disclaimer: Legal in California only for racing vehicles in sanctioned racing events.
