This results in extended drain intervals, which is a significant cost-saver for fleet managers and operators. Performance Characteristics and Benefits Engines utilizing 15-40w diesel oil benefit from a formulation that delivers robust thermal stability and resistance to oxidation.
Heavy-Duty Engine Performance with 15-40W Diesel Oil
The balanced nature of 15-40w makes it suitable for engines that do not experience extreme cold, such as those in northern temperate climates, or for vehicles that operate primarily in warmer environments but require a robust cold-weather spec for seasonal operation. Adhering to the recommended change intervals prevents the accumulation of contaminants that can degrade engine performance.
, Euro VI or EPA 2010), and the presence of exhaust after-treatment systems like Diesel Particulate Filters (DPFs) can dictate the required performance level. In the case of 15-40w, the "15" refers to the oil's viscosity during cold conditions, specifically at low temperatures tested at a specified shear rate.
Heavy-Duty Engine Performance with 15-40W Diesel Oil
This lower number compared to heavier grades allows the oil to circulate more quickly upon startup, reducing dry friction and wear on critical components. Understanding the 15-40w Viscosity Grade The Society of Automotive Engineers (SAE) viscosity rating system provides a standardized measure of how oil flows at different temperatures.
