A 20-50 oil that beats the competition by providing more horsepower, torque, and antiwear additives. Champion's exclusive shear stabilizer, for better-film strength, delivers better piston ring seal at peak temperature. With 2 times more ZDDP (Zince) compared to synthetic oils, Champion Racing XP provides more premium anti-wear protection in heavily loaded racing engines. As an added benefit, you only need to change the engine oil every 4 races with Champion Racing XP. This saves valuable time in the shop. Also it cuts the cost of oil by 75% vs changing it every race. We recommend changing the oil filter every race to inspect it for debris.
