Kendall GT-1 Competition SAE 20w-50 High Zinc Racing Motor Oil

Kendall GT-1 Competition Motor Oil 20w-50 with LiquiTek protection additive is a high-quality, conventional automotive engine oil designed for use in gasoline fueled passenger cars and light trucks that do not require an ILSAC GF-6 oil for warranty coverage. The SAE 20W-50 viscosity grade is especially recommended for use in high-performance street engines and competition engines, including both gasoline- and alcohol-fueled racing vehicles. 

Kendall GT-1 Competition Motor Oil 20w-50 with LiquiTek also contains a boosted level of zinc dialkyldithiophosphate (ZDDP) additive to provide additional wear protection and enhanced oxidation resistance in the most demanding applications. It is particularly recommended for use in turbocharged engines and in high-performance engines with flat-tappet camshafts, especially during the critical break-in period.

It also has the following benefits:

  • Exclusive Liquid Titanium protection additive provides extra protection against engine wear
  • Formulated for engines equipped with turbochargers or superchargers
  • Excellent resistance to viscosity and thermal breakdown at high temperatures
  • Protects against sludge and varnish formation
  • Protects against rust and bearing corrosion
  • Highly resistant to foaming
  • High ZDDP content for additional wear protection for engines with flat-tappet camshafts
  • Racetrack-proven performance

    Due to Kendall GT-1 competition 20w-50 having the highest amount of zinc, this is my choice of oil. Older cars with flat tappit cams still need this high zinc oil but it cant be found at local auto parts stores. So I order it directly from PSC a case at a time.
