Description

Engine Oil (aka Motor Oil or Finished Oil) have eleven different viscosity grades:

1. 0W
2. 5W
3. 10W
4. 15W
5. 20W
6. 25W
7. 20W
8. 30W
9. 40W
10. 50W
11. 60W

The Society of Automotive Engineers (SAE) developed a scale for both engine (motor oil grades) and transmission oils. These numbers are referred to as the weight of a motor oil.

Engine oils are blends of refined mineral oils with high performance additives. They are recommended for use in a wide range of applications including gasoline and light duty diesel engines found in passenger cars, agriculture, construction and certain hydraulic systems.
