Driven Racing Oil GP-1 Semi Synthetic

Race-grade protection without the full-synthetic price tag. GP-1 blends genuine Pennsylvania Grade base oil with select synthetic components and Driven's high-zinc (ZDDP) additive package, giving you a tough oil film under high load and heat.

This oil plays well with alternative fuels too—it's fully compatible with methanol, E85, and high-octane race gas, making it the go-to choice for drag racing, vintage imports, classic muscle cars, and modern performance builds alike. Whether you're building a street-strip warrior or a dedicated competition engine, GP-1 keeps your internals safe when it matters most. If you're breaking in a fresh build, Driven also offers a GP-1 Break-In formula that's specifically engineered for that critical running-in period.

If you're serious enough about your engine to upgrade every other component under the hood, you owe it the same commitment in your oil—and that's exactly what Speed Tuned Motorsports customers expect.
