Castrol® GTX® Classic is a high performance formula for push-rod, flat tappet engines and performance cam applications. It’s blended with high zinc and phosphorus content to help prevent premature aging, wear and metal fatigue on engines with high tension valve springs or performance modifications that create high contact pressure and extreme internal temperatures.


ZDDP anti-wear additives are heat activated, so they provide wear protection in areas of increased friction and stress. When engine parts move during operation, the sliding or rolling motion takes place on top of or within the ZDDP anti-wear film, which reduces the metal to metal contact. This protection is especially important in engines with flat tappet camshafts or engines modified to increase horsepower.
