GP-1 is built for racers who push engines to their limits. Made in the USA with Bradford, Pennsylvania–grade Legacy Base Oil, GP-1 delivers race-proven protection for when RPM climbs, boost hits hard, and tuning gets aggressive.

GP-1 delivers:
• Unbreakable film strength with natural cling to part surfaces
• Rock-solid stability under high RPM, boost, and nitrous
• Won’t wash out or dilute in alcohol-fuel
• High Zinc (ZDDP) protection for aggressive cams
