Lubricants for trucks, buses and fleets
Modern trucks and buses run DPF, SCR and EGR after-treatment, long highway miles and long drain intervals, often through Canadian winters. Engine oil, gear oil and transmission fluid all have to meet OEM specifications. For cars and light gasoline fleets, see the Automotive Service guide.

What the lubricants have to handle
- OEM requirementsCummins CES 20086, Detroit Diesel DFS 93K222, Volvo VDS-4.5 and Mack EO-S 4.5 for the engines in North American trucks and buses.
- After-treatmentAPI CK-4 oils protect DPF, SCR and EGR systems on Euro V/VI and EPA 2010+ engines.
- Long drain intervalsOxidation and soot control to stretch service intervals on highway fleets.
- Canadian winters10W-30 and full-synthetic 10W-40 flow at cold start-up and help fuel economy.
- Mixed fleetsCK-4 is backward compatible with CJ-4 and CI-4, so one oil covers older and newer engines.
- Heavy axle loadsGL-5 extreme-pressure gear oils protect hypoid axles, final drives and PTOs under full load.
