Classification of industrial oils based on viscosity This classification is mainly based on ISO viscosity grades, which define the oil’s kinematic viscosity at 40 °C with a permissible variation of ±10%. The ISO viscosity grade of industrial oils (explained in detail and compared with other viscosity grading systems on the next page) approximately represents the […]
A car engine spark plug is a small component, but it has a major responsibility and a direct effect on engine performance. It has a limited service life, after which it must be replaced with a new plug. When the spark plug can no longer perform properly, various engine problems will appear, and by paying […]
