Sunoco SR18 118 Octane Leaded Racing Fuel is the ultimate high octane racing for fuel for engines that have no restriction.
This fuel is sanctioned by: NHRA
Sunoco SR18 is designed for high compression, high RPM racing engines. It is the ultimate choice for large displacement engines especially those in Drag Racing and Truck Pulling where there are no compression ratio restrictions.
Sunoco SR18 is for off-road and racing use only. It contains additives to enhance stability and increase storage life. As with any gasoline, SR18 should be stored in opaque, tightly sealed containers where temperatures are stable. Handled under such conditions, the shelf life of Sunoco SR18 is 2 years or more.
