Sunoco SR6 is a 106 octane leaded race fuel designed specifically for racing engines that need the consistency and quality of an all-out racing fuel but don’t need the extra octane. Rest assured that this fuel is made from the same double-distilled, high purity racing fuel components that customers have come to expect from Sunoco since we started producing racing fuels many decades ago.
