Diesel Engine Oil for Heavy-Duty Trucks
VALVOLINE All Fleet Plus 15W-40 is a conventional lubricant built for diesel engines in commercial trucks. The one-quart bottle provides a convenient top-up size for fleet maintenance. It meets API and SAE standards and includes detergent additives to help control deposits and wear.
Suited for Mixed Fleets in Variable Climates
This oil serves operators who need a single viscosity grade across a wide temperature range, with a pour point of -22 degrees F and a maximum operating temperature of 220 degrees F. It is not intended for gasoline engines or for equipment requiring synthetic base stocks or specific OEM approvals not listed here.
SAE 15W-40 Viscosity Grade Decides Fit
The 15W-40 rating determines cold-start flow at -30 degrees F and high-temperature film strength at 220 degrees F. Match this grade exactly to the engine manufacturer's recommendation; a different viscosity grade will not provide the required protection.

Questions about this item
Does my diesel truck need any special preparation before I add this 15W-40 oil?
No special preparation is required beyond ensuring the engine is at operating temperature for proper drainage during an oil change.
Will this conventional 15W-40 formula protect older diesel engines with high mileage?
Yes, the detergent additives help control deposits and wear in older diesel engines while meeting SAE 15W-40 viscosity requirements.
How can I verify the oil is circulating correctly after I refill the crankcase?
Check the dipstick for the correct level, confirm oil pressure builds within seconds of starting, and listen for quiet valve-train operation.
