What is 15W40 Oil?
15W40 is a multi-grade engine oil primarily formulated for diesel engines, though some heavy-duty gasoline engines may also use it. The “15W” indicates its viscosity at cold temperatures (“W” for winter), meaning it flows like a 15-weight oil when cold. The “40” signifies its viscosity at operating temperatures, behaving like a 40-weight oil when hot. This dual rating allows it to protect engines effectively across a wide range of temperatures, from cold starts to high-heat operation.
It’s engineered to handle the higher pressures, soot, and acid buildup common in diesel engines, offering robust protection against wear, corrosion, and sludge formation. Many off-road vehicles and heavy machinery rely on this robust formulation.
The Economic Advantage of Bulk Oil
One of the primary benefits of 55 gallon 15W40 oil is cost savings.
