The viscosity of an engine oil is not an unchanging datum, it is influenced by temperature, speed of movement, and pressure. Viscosity index Oil viscosity index (VI - Viscosity Index) is a number that allows to evaluate the change in the viscosity of a lubricating oil as the temperature ...
The number before the W represents the oil viscosity at lower temperatures, while the second number (after the W) indicates the viscosity at operating temperatures. For example, this means that 5W30 engine oil has less viscosity at lower and higher temperatures when compared to 10W40. You should...
