Sunoco® HCR™ Plus is a high performance leaded racing fuel designed for racing engines with very high compression ratios. It is particularly beneficial in sustained high speed / high load applications such as asphalt and dirt oval racing. HCR Plus is very resistant to vapor lock, ensuring consistent fuel metering from the green flag to the checkered flag. Sunoco HCR Plus is recommended for engines with compression ratios exceeding 14:1.
