This action reduces friction, which in turn minimizes energy loss and excessive heat generation. Decoding the Viscosity Grade on the Label The numbers and letters printed on the oil container, such as 5W-30 or 10W-40, represent the oil's viscosity, or its resistance to flow.
The number preceding the "W" signifies how easily the oil flows at low temperatures; a lower number means better cold-start flow and reduced engine wear on startup. This vital fluid serves as the lifeblood of your engine, performing a complex array of functions that extend far beyond simple lubrication.
