Certain kinds of motor oils behave differently. Ideally, an engineer would prefer the oil viscosity to remain the same when the engine is hot as when it is cold. Motor oil includes additives developed ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...

Every fleet owner should know the basics about the viscosity of the lubricants they are using and why the viscosity matters. Fleets—especially mixed ones—require a variety of lubricants. This ranges ...

Viscosity the most important physical property of a lubricating oil, as determines how easily the oil circulates and its load carrying capability. Maintaining the correct balance between low viscosity ...
