Integrated Powertrain Lubrication Solutions for Commercial Fleets
High-alkalinity soot-dispersing heavy diesel engine oils, extreme-pressure hypoid axle gear lubricants, and extended-drain wheel bearing greases engineered to extend drain intervals up to 60,000 km, reduce fuel consumption, and eliminate road breakdowns across heavy logistics fleets.
Fleet Powertrain Tribology & Engineering Direct Answer
Commercial long-haul fleets and intermodal logistics haulers face fierce operational cost pressures, where unscheduled roadside breakdowns and premature engine wear destroy operational margins. Fleet managers require coordinated powertrain lubricants capable of surviving 60,000 km highway drain intervals across Euro V/VI tractor-trailers. The FOSS Fleet Powertrain Solution delivers three synergized products: (1) Heavy-Duty Engine Oil CK-4 15W-40 (TBN > 10.0 mg KOH/g per ASTM D2896, sulfated ash < 1.0 wt% per ASTM D874, HTHS > 4.1 mPa.s per ASTM D4683) dispersing diesel soot up to 4.5% while fully protecting DPF and SCR aftertreatment systems; (2) Heavy Hypoid Drive Axle Gear Oil GL-5 85W-140 (DIN 51517-3 CLP, Timken OK Load > 60 lbs per ASTM D2782) absorbing massive torque multiplication and shock loading on drive axle differentials; and (3) Extended-Drain Lithium Complex Wheel Bearing Grease (NLGI 2 with dropping point > 260°C per ASTM D2265 and water washout < 3.0% at 79°C per ASTM D1264) providing 150,000 km hub maintenance intervals. This triad reduces fleet total cost of ownership (TCO) by 18%, lowers fuel consumption via reduced parasitic drag, and protects fleets operating from freezing mountain passes to high-heat desert highways. Supplied in UN 208L steel drums and 1,000L IBC totes.
