Questions Shops Ask
10W-30 versus 15W-40 for my diesel fleet?
Per the data sheets: the synthetic 10W-30 CK-4 pours at -39 °C against the HD 15W-40's -43 °C cold crank advantage — both flow cold, but the 10W-30 keeps a thinner film for winter fuel economy. Most Texas fleets run 15W-40 year-round (G1540-D); the 10W-30 CK-4 is the severe-cold and mixed-service pick. Call (817) 865-3707 and we will match it.
