37463 Prime Series 15W-40 Heavy Duty Diesel Engine Oil | 3/1 Gallon Case
Keep your diesel engines operating at peak performance with Prime Series 15W-40 Heavy Duty Diesel Engine Oil. Delivered in a convenient, space-saving case of three 1-gallon jugs, this premium heavy-duty lubricant is engineered to provide reliable engine defense for commercial fleets, agricultural equipment, and high-mileage diesel work trucks.
Formulated with high-quality base oils and a robust additive package, Prime Series 15W-40 delivers strong thermal stability and excellent soot control. It prevents harmful engine deposits, resists oil thickening, and reduces component wear under heavy payloads, making it a cost-effective solution for owner-operators and fleet managers looking to minimize maintenance costs.
Key Features
- Heavy-Duty Wear Protection: Advanced anti-wear additives shield critical valve train components, cylinders, and pistons from abrasive friction and wear.
- Superior Soot Dispersancy: Actively keeps soot particles suspended in the oil to prevent engine sludge, varnish buildup, and oil-filter plugging.
- Thermal Breakdown Resistance: Maintains stable viscosity and oil film strength during long hours of continuous operation or under heavy towing loads.
- Corrosion & Rust Defense: Neutralizes acidic combustion byproducts to protect vital internal engine bearings and yellow metals from corrosive pitting.
- Convenient 3-Gallon Case: The 3-pack case configuration offers the perfect volume for standard mid-sized diesel oil changes or convenient top-offs on the jobsite.
Applications & Fleet Fitment
Optimized for use in heavy-duty diesel engines, including turbocharged and naturally aspirated configurations operating in transport, construction, and farming environments.
- Industry Standards: Formulated to meet or exceed heavy-duty diesel service classifications (such as API CK-4, CJ-4, or CI-4 regulations depending on vehicle vintage).
- Target Vehicles: Ideal for Class 8 line-haul trucks, medium-duty delivery box trucks, diesel pickup trucks (Ford PowerStroke, Chevy Duramax, RAM Cummins), and off-highway tractors.
- Fuel Compatibility: Safe for use with ultra-low sulfur diesel (ULSD) and standard biodiesel fuel blends.
