Kendall GT-1 High Performance Motor Oil is a high-quality engine
oil specially designed for use in gasoline engines operating under
high-temperature or severe driving conditions, as well as in
competition engines and high-performance street engines. It is
formulated to provide excellent wear protection, to minimize the
formation of sludge and varnish, and to resist viscosity and
thermal breakdown even in severe service. It also protects
against rust and bearing corrosion, and has good foam
resistance. The SAE 20W-50 viscosity grade is fortified with
additional zinc dialkyldithiophosphate (ZDDP) additive to provide
enhanced wear protection and oxidation resistance for use 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.
Applications
GT-1 High Performance Motor Oil is recommended for use in
passenger cars, light trucks and sport utility vehicles that do not
require an ILSAC GF-4 oil for warranty coverage, as well as in
competition engines and high-performance street engines. The
SAE 20W-50 viscosity grade is fortified to provide enhanced
wear protection for use in racing applications and in engines with
flat-tappet camshafts. The Nitro 70 grade is specially formulated
for use in nitromethane-fueled drag racing vehicles. The SAE 30,
40 and 50 viscosity grades are recommended for use in older
vehicles where use of single-grade motor oil is specified.
GT-1 High Performance Motor Oil meets or exceeds the
requirements of:
• API Service SM, SL (all grades except SAE 50 & Nitro 70)
Features/Benefits
