  • The cold viscosity of engine oil for Audi S4 (number in front of the letter “W”, which stands for “Winter”): This value will show the engine’s ability to begin cold depending on the viscosity of the oil. 0W means -30°C; 5W means -25°C, 10W means -20°C and 15W means -15°C. It is therefore up to you to adapt it to the climatic conditions in which you drive your Audi S4.
  • The hot viscosity of the engine oil for Audi S4 (value following the “W”): Value between 20 and 60, it is essential to keep in mind that the higher the value, the thicker the layer of oil you will have when hot to protect your engine unit, and the lower the value, the less friction you will have when hot and therefore lower your consumption. However, if you use your Audi S4 in the city, or with a sporty driving style, it’s better to protect it although hot.
  • The specifications : They are created on the back of the oil canister you can discover them such as “ACEA C1 – C4” or “VW 500. 01”, are just specifications of compatibility with different brands of cars, you have to verify in the instructions of your Audi S4 that the oil in question is compatible with your engine unit.

The different types of engine oil for your Audi S4

  • Semi-synthetic 10w40: This oil has a good quality/price ratio and is said to be semi-synthetic because it is still composed of specific elements that will improve its lifetime. It is thus appropriate for a polyvalent use of its car. Moreover, it favours a simpler cold begin than a mineral oil. Nevertheless, you should remember to change the oil every 10, 000km.
  • The “synthetic” oil 5w40: This sort of oil is really adapted to the recent Audi S4 engines, in fact, the protection of the engine unit will be optimum and the cold begin too. It is therefore a good choice either for people who drive in city centres, who have a sporty driving style, or who drive long distances and want to limit the frequency of their oil change.
