"W" - specifies the level of oil viscosity, it W means "winter". “9” - specifies the level of viscosity at the temperature below zero. If this number is less, then the viscosity will be less. The characteristic viscosity at high temperatures shows the last number labels than it is large, then the viscosity will be more.
The amount of oil in the engine of the car is determined using the computer or special measuring probe, which has two marks.
