Premium Full-Synthetic Passenger Car Engine Oil; Fortified with Liquid Titanium® Protection Additive Kendall® GT-1 Full Synthetic Motor Oil with Liquid Titanium protection additive is a premium quality, full-synthetic automotive engine oil designed to provide maximum engine protection for gasoline-fueled and flex-fuel passenger cars and light trucks under all operating conditions. It is particularly recommended for vehicles operating at extreme temperatures or under severe driving conditions, such as towing heavy loads. GT-1 Full Synthetic with Liquid Titanium is formulated with synthetic base stocks and a performance additive package fortified with our exclusive Liquid Titanium protection additive for extra wear protection and improved fuel savings. The full-synthetic formulation, compared with conventional engine oils, provides improved protection against viscosity breakdown and deposit formation at high temperatures; lower volatility for reduced oil consumption; and faster oil circulation at low temperatures for easier starting and better protection during cold starts. The Liquid Titanium protection additive provides increased engine protection by forming a strongly bonded titanium shield on the surface of critical engine parts, which reduces friction and wear and can help extend engine life. Reduced friction also helps improve fuel economy performance beyond ILSAC GF-5 requirements. GT-1 Full Synthetic with Liquid Titanium exceeds new car warranty requirements as defined by ILSAC GF-5. It meets or exceeds "Resource Conserving" requirements for fuel economy improvement, emission system and turbocharger protection, and protection of engines operating on ethanol-containing fuels up to E85. It is backward serviceable for use where API SM or earlier "S" category engine oils are recommended.
