SAE 10W40 Motor Oil 6x1 Quart

Lucas Oil SAE 10W40 Motor Oil 6x1 Quart is a conventional mineral-based engine lubricant engineered for year-round protection across light-duty and medium-duty applications. This six-quart bulk pack is ideal for fleet operators, maintenance technicians, and vehicle owners who demand reliable oil changes without frequent trips to resupply. The 10W40 weight classification delivers cold-start fluidity in winter conditions while maintaining robust film strength at elevated summer temperatures.

The 10W (winter) rating ensures prompt oil circulation at low temperatures, reducing engine wear during cold starts when oil viscosity naturally thickens. The 40 (operating) rating provides stable viscosity across normal driving ranges and under sustained load, preventing excessive thinning that compromises bearing protection. Lucas Oil's conventional formulation includes detergent and anti-wear additives that minimize sludge buildup, extend drain intervals, and protect critical engine surfaces including pistons, valves, and crankshaft journals from oxidation and corrosion.

This six-quart set suits vehicles with 4- to 6-quart oil capacities, making it practical for single oil changes or split between two maintenance cycles. Compact individual 1-quart bottles enable easy handling, transport, and precise pouring without bulk storage concerns. Lucas Oil 10W40 is compatible with gasoline engines in sedans, light trucks, SUVs, and vintage vehicles that do not require synthetic or high-performance specifications—check your owner's manual for the manufacturer's recommended viscosity grade before purchase.
