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.
