GP-1 20w50 Conventional Oil Case 4 x 1 Gallon

The GP-1 20W50 Conventional Oil Case 4 x 1 Gallon from DRIVEN RACING OIL is engineered for builders and enthusiasts who demand reliable engine protection during high-performance driving and heavy-duty operation. This four-gallon case format is ideal for workshop stocking, fleet maintenance, and serious gearheads who run consistent oil intervals across multiple vehicles. Whether you're breaking in a fresh engine build, maintaining a lifted truck, or keeping a well-tuned street machine running strong, having a full case on hand eliminates last-minute supply runs and ensures you're never caught without quality lubricant.

The 20W50 viscosity rating delivers multi-grade performance by flowing freely at cold startup—critical for morning commutes and winter operation—while maintaining robust film strength at sustained operating temperatures. Conventional formulations like this provide time-tested protection through proven base stock and additive packages, making them cost-effective for older platforms and low-mileage seasonal vehicles that don't require full synthetic properties. The higher 50-weight rating excels in older engines with loose tolerances and in modification applications where prolonged high-rpm operation or boost pressure demands thicker oil cushioning between bearing surfaces.

This case suits mechanics and DIY builders maintaining carbureted engines, classic hot rods, vintage trucks, and naturally aspirated performance builds where conventional oil is the standard choice. The 31.955 lb total weight and compact 12 x 9 x 15 inch footprint fit easily on shop shelves or garage storage racks. DRIVEN RACING OIL's commitment to affordability without sacrificing baseline protection makes this case a smart investment for repeat oil changes throughout the year, giving you consistent lubrication across your fleet without premium pricing.
