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 ...

Engine oil needs to form a protective film, which prevents metal to metal contact. “An old axiom in the lubricants business is to use the lightest viscosity oil that will adequately protect the ...

That means these engines usually need lower-viscosity oil—oil that is “thinner” and flows more easily to form a cushion of lubrication between two parts. At lower viscosity, synthetic oil ...

Any internal combustion engine-powered vehicle requires a host of essential fluids and engine oil is a major one among them. While we take our cars to service centres the workshops often pour ...

Using the best engine oil additive can help improve the performance and longevity of your engine in a variety of ways. Most change the viscosity of the engine oil. Some also provide a coating of ...
