It is a primary component of how SAE oil grades are defined (15W-40, 10W-30, 5W-40, 5W-30, etc.). Absolute viscosity is expressed as centipoise (cP). It is a measure of frictional drag within the ...

In the past, there have been similar shifts in preferred engine oil viscosity grades. An example is the transition in heavy duty diesel engine oils in the 1980s from monograde viscosity SAE 30 and ...

For these engines, we will recommend you the full synthetic engine oil grade SAE 5W – 40 of any reputed brand.
