Sunoco Race Fuel: GT Plus Unleaded 104 octane fuel, 5 gallons in a UN/DOT approved and reusable container. Sunoco 260 GT Plus is a highly oxygenated unleaded race fuel. Due to its high oxygen content, 260 GT Plus is for off-road and racing use only. However, it will not harm sensors such as 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. Exposure to sun light (ultraviolet light) can degrade the octane of this fuel and must be avoided. Properly stored, the shelf life of 260 GT Plus is in excess of 1 year. A $37 HAZ MAT fee is shown as a handling charge; the shipping cost will show in the shipping line on the final page as well. Ground shipment only; No Air shipments allowed. No Sales Tax - Excise Tax Already paid - do not forget to claim a credit for tax paid for off road use. EXTRA OXYGEN (4.5 PERCENT) IN THIS RACE FUEL - THIS IS THE SECRET WEAPON FOR STOCK DRAG CARS, RICEBURNERS, SCCA SOLO AND RALLY X RACERS - like Scott Leonard of Essell Rally Racing (Pictured). NOT LEGAL FOR STREET USE - DOES NOT MEET EPA REGULATIONS.
