The primary purpose of engine oil is to stop metal from touching metal. When metal surfaces come in contact, they grind together causing friction. That creates heat, stress and wear. Engine oil is ...

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 ...

Engine oils and lubricants need to provide a good layer thickness by having sufficient viscosity, without giving significant frictional effects from the viscosity being too high. The ideal viscosity ...

Stricter federal regulations are reshaping the engine oil industry. PC-12 and low-viscosity HDEOs can help with compliance and performance. As the temperatures rise and the days become longer, your ...
