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.
Oil typeSynthetic Oil
Mineral oil: directly coming from crude oil, this is a cheap solution, often recommended for old vehicles.
Fully synthetic oil: coming from chemical synthesis, the oil goes through several operations to purify it and enrich it with additives for a better engine protection. It is less impacted by extreme temperatures and better keep its properties over time.
Semi synthetic oil: coming from a mix of mineral & fully synthetic oils.
