Castrol GTX Classic 20W-50 Conventional Motor Oil, 5 Quarts

Castrol® GTX® Classic is specially formulated for classic/collector cars, muscle cars, hot rods and race cars. It 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. Protect your investment with the Castrol Engine Warranty – with coverage for up to 500K miles. Enrollment is quick, easy and FREE! Learn more and register at www.castrolenginewarranty.com
