The owner's manual for your car will list its recommended oil weight, whether that's a standard format like 10W-30 or something more unusual. That number refers to the viscosity (or thickness ...

One way to do that is by using a low viscosity oil. The less energy an engine uses to lubricate itself, the less gas it uses in the process. There's also the fact that as engine technologies and ...

An odd solid that can flow like a fluid has been created from light for the first time. Studying it will help researchers better understand exotic quantum states of matter. “We actually made lig ...

Philadelphia schools took the atypical approach of announcing a full day in advance that it would go virtual Friday, Jan. 7, as the area was expected to receive one to three inches of snow overnight.

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 ...

Consider viscosity and oil temperature range when selecting a hydraulic fluid. Make sure when you replace the fluid that you are at least using the same type. Most industrial fluids use the ISO ...
