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 ...

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 ...

The term “Nanofluids” was first proposed by Choi of Argonne National Laboratory USA in 1995, which meant nanoparticle fluid suspensions. After which, this interdisciplinary field has developed ...

As General Motors prepares to launch its Gen 6 Small Block V8 engine family in conjunction with its next-gen light-duty pickup trucks, GM Authority has been bust serving up a variety of critical ...

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey ...

The second car that I ever owned was a 2002 Chevy Silverado 2500 with a 6.6L Duramax diesel engine under the hood. It wasn't my first choice, but it was a hand-me-down from my father after my 1993 ...

An international team of scientists has discovered how cancer cells exposed to high viscosity environments change the way they move to improve their invasiveness and favor metastases. The studies ...

The oil you put in your engine matters. After all, your engine contains many moving parts that must remain lubricated to work properly. Otherwise, your engine could develop some serious wear and tear.
