SAE 15W-40 synthetic blend diesel engine oil for on-highway trucks, diesel pickups and off-road equipment
Bedrock 15W-40 is a synthetic blend heavy-duty diesel engine oil in the grade that heavy-duty diesel engine makers list as the standard fill for on-highway trucks and off-road equipment. It is meant for the engines that work along the Gulf Coast: over-the-road tractors, vocational trucks, diesel pickups, and the loaders, dozers and tractors that run on construction sites and farms. One grade covers a mixed fleet, which keeps the shop's oil inventory simple.
In service, the oil has several jobs at once. At start-up it needs to reach the turbocharger and the upper engine quickly, and at operating temperature it needs to keep a full oil film between pistons, rings, bearings and the valve train. Heavy-duty diesel oils in this grade also carry soot and combustion by-products in suspension until the oil is drained, so they do not settle as sludge or build deposits on hot parts.
Bedrock 15W-40 is the core grade of the Bedrock engine oil line and the one to stock when a fleet runs one oil across trucks, pickups and equipment. Fleets whose engine makers allow a lighter grade can look at Bedrock 10W-30; engines that need a heavier film at operating temperature move up to the 15W-50 or 20W-50. It comes in all five package sizes, from the 1-gallon jug to the 275-gallon tote.

Applications
- Over-the-road tractors in regional and long-haul service
- Vocational trucks: dump trucks, mixers, roll-offs and refuse trucks in stop-and-go city work
- Diesel pickups that tow and haul for work, where the owner's manual calls for a 15W-40 heavy-duty oil
- Construction equipment: excavators, loaders, dozers and compactors
- Farm tractors, combines and irrigation engines
- Oilfield service trucks and stationary diesel engines on well sites
- Mixed fleets that standardize on one engine oil across trucks, pickups and equipment
Performance
- Keeps a stable oil film on pistons, rings, bearings and valve train parts under sustained load
- Holds soot and combustion by-products in suspension so they drain out with the oil instead of forming sludge and deposits
- Resists oxidation and thickening through long hours at operating temperature
- Reaches the turbocharger and upper engine quickly on start-up
- Helps protect against rust and corrosion during shutdowns and wet weather
- Formulated for use where a 15W-40 heavy-duty diesel engine oil is specified
