GP-1 10w30 SemiSynthetic Oil Case 12 x 1 Quart

The GP-1 10W30 Semi-Synthetic Oil Case from DRIVEN RACING OIL is purpose-built for mechanics and enthusiasts who demand reliable engine protection without the premium cost of full synthetics. This 12-quart case offers convenience and value for workshops, fleet maintenance, and individual vehicle owners running modern and modified engines alike. Whether you're maintaining daily drivers or fine-tuning performance builds, a semi-synthetic 10W30 strikes the balance between thermal stability and affordability that serious automotive work requires.

DRIVEN RACING OIL's semi-synthetic formulation blends mineral and synthetic base stocks to deliver superior oxidation resistance and extended drain intervals compared to conventional oils, while maintaining excellent cold-flow properties at startup. The 10W viscosity rating ensures rapid circulation during winter or cold-engine cranking, reducing wear during the critical first seconds of operation—essential when you've invested in upgraded pistons, bearings, or turbo systems. The 30-weight film strength provides stable protection across moderate to high operating temperatures, supporting both street and light performance applications without excessive thinning at heat.

This case format is ideal for professional mechanics stocking inventory, fleet operators managing multiple vehicles, and serious hobbyists who service their own builds regularly. The GP-1 10W30 semi-synthetic formulation works across gasoline engines from stock to mildly modified power levels, and remains a trusted choice for naturally aspirated and early forced-induction platforms. Individual 1-quart bottles allow flexible top-ups between service intervals, and the case quantity reduces per-unit cost while eliminating frequent reordering for active shops.
