XLO Heavy Duty Fleet Oil 15w40 Case 1 Gallon

The XLO Heavy Duty Fleet Oil 15w40 Case 1 Gallon is specifically formulated for commercial and industrial fleet operations that require robust engine protection under extreme conditions. This oil is ideal for managing equipment fleets in construction, logistics, and heavy-duty work vehicles, addressing the demanding needs of both diesel and gasoline engines.

This AMALIE formulation features a 15w40 viscosity grade, providing optimal cold-start flowability and high-temperature film strength. It delivers a thinner viscosity at startup to reduce drag and ensure rapid oil circulation, thickening to a 40-weight at operating temperature to maintain a protective boundary layer. The oil includes anti-wear additives and detergent packages that help combat sludge accumulation and protect against rust, making it suitable for high-stress environments.

Fleet managers and mechanics will find this heavy-duty oil particularly beneficial for servicing a variety of vehicles, including pickup trucks and work vans. Its formulation is designed for extended drain intervals, making it a reliable choice for those operating under demanding conditions. However, users should verify compatibility with specific light-duty diesel applications to ensure optimal performance.
