Noticing premature camshaft lobe wear? Trouble with your lifters wearing oddly? Years back all motor oil had a zinc additive to help with cam break-in and lengthen the overall lifespan of your camshaft and lifters. You can supplement any motor oil with ZDDP additives, but those are expensive. Why not just use an oil like you used to? 20W-50 motor oil with zinc is the only oil we recommend here at the No Name.
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. Specially formulated engine oil for classic/collector cars, muscle cars, hot rods and race cars.
Sold in individual or five quart increments.
Suitable for all Vintage Volkswagens.
