Product Details

GTX™ Classic SAE 20W-50 Conventional Hich Zinc Content Motor Oil by Castrol®. 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.


Oil Type: Conventional
Viscosity Grade: SAE 20W-50
Volume: 1 Quart

API Oil Standards: API SJ


  • Specialized additives containing high Zinc and Phosphorus for extreme wear protection
  • Formulated to maintain tough and thick oil film even under severe conditions
  • Minimal foaming and high resistance to thermal degradation
  • Compatible with gasoline and alcohol based fuels

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.

Today’s engines are smaller, more powerful and under more pressure than ever before. Castrol EDGE has been engineered to withstand the stress of modern engines and provides 10X better high temperature performance than the latest industry standard. Did you know that friction can waste up to 10% of an engine's performance? Increased demands placed on the engine to deliver power and fuel efficiency create intense friction between critical engine parts. Castrol EDGE transforms its structure under pressure to keep metal apart and reduce friction for maximum engine performance and delivers 6X better wear protection than required by the latest Sequence IVA test limits.
