GP-1 50W Conventional Oil Case 4 x 1 Gallon

The GP-1 50W Conventional Oil Case 4 x 1 Gallon is engineered for builders and mechanics who demand reliable, budget-conscious engine protection across street and track applications. This four-pack configuration (SKU JGP19516-4) delivers DRIVEN RACING OIL's proven conventional formulation, making it ideal for stock rebuild projects, vintage restorations, and high-mileage daily drivers where synthetic blends may be unnecessary. Whether you're refreshing a long-block assembly or maintaining a fleet of shop vehicles, this case format reduces per-quart costs while ensuring consistent quality across multiple oil changes.

DRIVEN RACING OIL's GP-1 50W viscosity grade delivers robust film strength at operating temperatures, supporting traditional bearing loads and ring-pack sealing without the additive complexity of synthetics. The 50-weight formulation provides adequate cold-start pumpability while maintaining stable viscosity under sustained engine load—critical for carbureted engines and naturally aspirated powerplants where oil shear resistance directly impacts bearing longevity. Conventional mineral basestocks allow superior compatibility with older gasket materials and seals, eliminating the risk of incompatibility issues that sometimes arise when switching from vintage oils to modern synthetics on restoration projects.

Mechanics and engine builders running stock or mildly modified carbureted engines, marine inboards, and vintage truck platforms benefit most from this conventional 50W oil's proven track record. The individual 1-gallon jugs offer convenient storage and portion control, preventing oxidation that occurs when bulk drums sit partially empty in shop environments. This case is compatible with any gasoline engine specifying 50-weight conventional mineral oil—confirm your engine's published oil specification before installation to ensure proper viscosity and additive package matching.
