Sunoco Maximal 116 Octane, Leaded Racing Fuel is meant for extreme performance motor sports.
This fuel is sanctioned by: NHRA
Sunoco Maximal is designed for high revving and high compression in big bore, large displacement naturally aspirated engines. This drag racing fuel has especially proven itself in highly stress big block engines used in Truck and Tractor pulling. Additionally, Sunoco Maximal is very resistant to vapor lock, ensuring consistent fuel metering between passes.
Sunoco Maximal is for off-road and racing use only. It contains additives to enhance stability and minimize oxidation. As with any gasoline, Maximal should be stored in opaque, tightly sealed containers where temperatures are stable. Handled under such conditions, the shelf life of Sunoco Maximal is 2 years or more.
SUNOCO TECH CORNER
High-revving, high-compression, big-block engines–picture something extreme, like a big-block Corvette, 427 Cobra or Ford GT40–need a lot of octane plus a lightweight fuel that will provide a fast flame front across those large-diameter pistons. A 116-octane fuel like Sunoco’s Maximal is designed for these situations, Sunoco's Santner explains.
Leaded fuels are not compatible with catalytic converters and oxygen sensors. Unleaded fuels will be limited to 104 octane.
