XLO Heavy Duty Fleet Oil 15w40 Case 4 x 1 Gallon

The XLO Heavy Duty Fleet Oil 15W40 Case (4 x 1 Gallon) is purpose-built for high-performance diesel and gasoline engines operating in demanding field conditions. Whether you're managing a tactical vehicle fleet, support logistics operations, or running commercial heavy-duty equipment under extreme load, this AMALIE formulation delivers reliable engine protection when mission readiness depends on equipment reliability. Law enforcement and military personnel recognize that engine oil selection directly impacts vehicle uptime, and this heavy-duty blend is engineered for exactly those operational demands.

The 15W40 viscosity rating provides robust protection across thermal extremes—critical when vehicles operate in arctic staging areas or desert deployment zones where temperature swings exceed 100 degrees. The XLO formulation incorporates anti-wear additives that protect hydraulic lifters and cam followers under sustained high-rpm operation, while superior detergency keeps piston rings and valve trains clean during extended idling or stop-and-go tactical movements. The heavy-duty additive package resists shear and oxidation, maintaining film strength even in engines prone to sludge buildup during extended service intervals common in field operations.

This case format—four 1-gallon containers—is ideal for fleet maintenance programs where portability and inventory control matter. Tactical operations officers and fleet mechanics appreciate the convenience of single-gallon jugs for topping off reservoirs in field conditions without committing to bulk storage. Compatible with most diesel pickup trucks, commercial transport vehicles, and older gasoline powerplants rated for 15W40 service, this oil meets or exceeds API CJ-4 performance standards for both light-duty and severe-duty operation. Store the case in a temperature-controlled environment and rotate stock according to FIFO protocols for optimal shelf life.
