Designed for competition vehicles, classic cars, and imports, with high performance engines requiring a 5W-20 viscosity. GP-1 is compatible with Methanol, E85, and high octane race fuel. Blended with genuine Pennsylvania Grade base oil, GP-1 achieves a higher Pressure-Viscosity Coefficient for excellent HTHS film thickness. GP-1 delivers maximum engine protection by utilizing Driven?s High Zinc (ZDDP) additive technology. The 5W-20 viscosity is ideal for modern engines with stock bearing clearances or competition engines with lower oil temperatures, especially those with flat tappet, roller, or overhead cams. Viscosity typical of 5W-20.

Key Benefits of Driven Racing Oil GP-1 for Your High-Performance Engine:

Outstanding Film Strength and Cling: Leveraging the natural properties of Legacy Base Oil from Bradford, PA, GP-1 ensures excellent film strength and a protective cling that shields engine parts under high loads, even with boost and nitrous applications.
High Zinc (ZDDP) Additive Technology: With advanced zinc and phosphorous additives, GP-1 offers maximum anti-wear protection for flat tappet, roller, and overhead cam engines, safeguarding aggressive cam profiles and high spring pressures.
Reduced Wear from Extreme Conditions: GP-1 minimizes wear from thrust loading, crankshaft flex, and loss of lubrication, making it ideal for engines under high stress.
Superior Resistance to Fuel Dilution: Perfect for engines running on alcohol fuels, GP-1’s unique properties protect the piston ring and cylinder wall interface, ensuring better ring seal and overall engine integrity.
Exceptional Engine Cleanliness: Powerful detergents and dispersants keep the engine clean, while foam inhibitors prevent air entrainment at high RPMs, maximizing oil filter efficiency and overall performance.
