Maximal

Sunoco Maximal is a 116 octane, extreme performance leaded racing fuel designed for high revving racing engines with high compression ratios.  Maximal’s fast burn rate makes it particularly beneficial in large-bore, large-displacement naturally-aspirated drag racing applications.  It has also proven to be very popular in the highly-stressed naturally-aspirated big blocks used in truck pulling.  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 oxidative effects.  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.

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