GP-1 5w20 Semi-Synthetic Oil Case 12 x 1 Quart

The GP-1 5W20 Semi-Synthetic Oil Case delivers reliable protection and performance for street-driven vehicles and weekend warriors who demand consistent engine lubrication without premium synthetic pricing. This case contains 12 one-quart bottles of DRIVEN RACING OIL's GP-1 formulation, engineered for drivers who understand that proper oil selection directly impacts engine longevity, startup performance, and thermal stability across varied driving conditions. Whether you're maintaining a daily commuter, a modified street car, or rotating through a small fleet, having a case on hand ensures you're never caught short when it's time for an oil change.

The 5W20 viscosity rating means this semi-synthetic blend flows freely in cold starts (5-weight winter rating) while maintaining a stable 20-weight film at operating temperature, a critical balance for modern engine tolerances and variable valve timing systems. Semi-synthetic blends combine mineral oil's cost-effectiveness with synthetic additives that resist oxidation, extend drain intervals, and improve shear stability under load—ideal for naturally aspirated and lightly boosted engines that don't require full synthetic investment. The DRIVEN Racing Oil formulation includes detergents that keep valve trains and piston crowns clean, anti-wear agents that protect bearing surfaces, and thermal stability that resists breakdown during sustained acceleration or towing.

This case is ideal for technicians, weekend mechanics, and enthusiasts maintaining multiple vehicles or performing frequent service intervals on street performance builds. The 5W20 specification suits most modern domestic and import four-cylinder engines, many V6 platforms, and light-duty trucks—always verify your owner's manual or service documentation before selecting oil weight. Bulk case purchasing reduces per-quart cost compared to individual bottles, making it economical for shops, fleets, or serious hobbyists who understand that consistent, quality oil changes are the foundation of engine reliability and resale value.
