GP-1 40W Conventional Oil Case 4 x 1 Gallon

The GP-1 40W Conventional Oil Case from DRIVEN RACING OIL is designed to provide reliable engine protection for both street machines and track-focused builds that require consistent lubrication across a wide temperature range. This conventional oil formula is ideal for automotive enthusiasts who seek effective engine maintenance without the higher costs associated with synthetic oils, making it suitable for classic restorations, daily drivers, and modified vehicles.

Engineered with a mineral base stock and a robust additive package, this oil establishes stable film strength under sustained engine load and heat cycling. The 40-weight viscosity ensures optimal flow at startup while providing adequate protection during extended driving and light performance applications. It effectively protects critical engine components, including bearing surfaces, valve trains, and piston rings, across varying ambient temperatures.

This four-gallon case is favored by mechanics and weekend builders for fleet maintenance, multi-vehicle shops, and garages looking to standardize on a single reliable oil grade. DRIVEN RACING OIL formulates its products to meet real-world engine demands, managing shear stress, deposit control, and wear prevention effectively for rebuilds, stock powerplants, and mildly modified engines operating within conventional parameters.
