Commercial Vehicles

Heavy-duty engine oils, driveline fluids, and DEF for trucks, buses, and vocational fleets.

A commercial vehicle earns nothing parked. Oil drain intervals, aftertreatment protection, and cold-weather starting are maintenance decisions with a direct line to uptime.

Star West supplies API CK-4 and FA-4 heavy-duty engine oils, synthetic gear lubricants and transmission fluids, greases for fifth wheels and chassis points, and diesel exhaust fluid — delivered in drums, totes, or bulk to your yard. Our lubrication equipment line covers the dispensing side, from reels and meters to waste oil handling.
