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 it 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 used in fuel injection systems.  Due to its high oxygen content, a richer air/fuel mixture is required to utilize the full potential of this fuel compared to a conventional non-oxygenated race fuel.

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.
