10w30 Petroleum Oil 6x1 Qt

Lucas Oil 10W30 Petroleum Oil 6x1 Qt is a conventional mineral-based motor oil formulated to protect engines in marine vessels, classic cars, and hot rods. Built for boaters and enthusiasts who demand reliable engine protection in demanding conditions, this six-quart case offers the convenience of bulk storage while maintaining consistent quality across multiple change intervals. The 10W30 viscosity grade delivers year-round performance, flowing freely in cold starts while maintaining film strength at operating temperature.

This petroleum-based formula incorporates elevated zinc content—a key additive for flat-tappet and high-performance cam engines common in marine powerplants and classic applications. High zinc levels provide superior anti-wear protection, reducing friction and metal-to-metal contact during startup and sustained operation. The conventional mineral base resists oxidation and sludge formation, critical in engines that experience thermal cycling and extended idle periods typical of recreational boating. Each 1-quart bottle is pre-measured for straightforward oil changes without waste or guesswork.

Boaters running older inboard engines, classic wooden or fiberglass hulls with vintage powerplants, and hot rod enthusiasts benefit most from Lucas Oil's zinc-rich formulation and proven thermal stability. The six-quart packaging reduces storage burden while ensuring fresh oil across multiple service intervals—essential for seasonal boaters who may sit idle for months. Compatibility spans carbureted and early fuel-injected marine engines, flat-tappet performance engines, and any application requiring conventional mineral oil with enhanced anti-wear properties. Store in a cool, dry location away from direct sunlight; the compact 8.8 x 7.8 x 9.2 inch case fits standard marine lockers and engine compartments.
