Mammoth Petroleum proudly supplies Kendall GT-1 Competition Motor Oil with LiquiTek, a high-quality conventional automotive engine oil engineered for gasoline-fueled passenger cars and light trucks that do not require an ILSAC GF-7 oil for warranty coverage. The SAE 20W-50 and SAE 50 viscosity grades are specifically recommended for high-performance street engines and competition engines, including both gasoline- and alcohol-fueled racing vehicles.

Formulated to deliver exceptional performance in severe service, GT-1 Competition Motor Oil provides:

• Robust Wear Protection: Minimizes sludge and varnish formation while resisting viscosity and thermal breakdown.

• Corrosion and Foam Resistance: Actively protects against rust and bearing corrosion while maintaining high resistance to foaming.

• 
  

The SAE 20W-50 grade features a boosted level of zinc dialkyldithiophosphate (ZDDP) additive to deliver maximum wear protection and enhanced oxidation resistance. This specialized grade is strongly recommended for turbocharged engines and high-performance applications featuring flat-tappet camshafts, making it the ideal choice for the critical break-in period. Keep it Kendall.
