The viscosity has 2 grades:
- The cold flow (the numbers before the W of winter): the closer to 0 the number is, the more liquid the oil is at low temperature, which will simplify cold start.
- The performance at high temperature: the higher the number is, the more viscous the oil is at high temperature.
The information about which viscosity to use for your vehicle is available in your maintenance book.
