What is Lubricant

Engine oil

Viscosity specifications
2 Grades of SAE viscosity specifications are determined by Low-Temperature Viscosity(CCS, MRV) & High-Temperature Viscosity(Kinematic viscosity at 100°C, HTHS).

Complying with SAE(Society of Automotive Engineers) J300 standard.

 

Mono grade engine oil

This oil has only one kind of features which works well in low temperature or in high temperature like SAE 10W, SAE 20, SAE 30 etc.

This oil is used in place where there is not much temperature change.

 

Multi grade engine oil

For example of SAE 15W-40 product, it has two features of SAE 15W(working well in low temperature) and SAE 40(working well in high temperature).

Oil is stiff in low temperature and watery in high temperature. Diverse class viscosity engine oil is a bit stiff in low temperature and is not too watery in high temperature.

It is most popularly used product in the world.
