  • The cold viscosity of engine oil for Audi A6 (number in front of the letter “W”, which stands for “Winter”): This value will indicate the engine’s ability to start cold based 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 consequently up to you to modify it to the climatic conditions in which you drive your Audi A6.
  • The hot viscosity of the engine oil for Audi A6 (value following the “W”): Value between 20 and 60, it is important to keep in mind that the higher the value, the thicker the layer of oil you will have when hot to protect your engine, and the lower the value, the less friction you will have when hot and consequently lower your consumption. However, if you use your Audi A6 in the city, or with a sporty driving style, it’s better to protect it while hot.

The different types of engine oil for your Audi A6

  • “Mineral” engine oils 15w40: They are called mineral oils because they are specifically made up of crude refined oil, which will give them maximum viscosity and consequently a thickness suitable for old engines that tend to consume oil. However, the truth that they are natural will bring about them to lose their lubricating properties more quickly, so it will be necessary to shorten the intervals between oil changes.
  • 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 boost its lifespan. It is thus appropriate for a polyvalent use of its vehicle. Additionally, it favours a simpler cold start than a mineral oil. On the other hand, you should make sure to replace the oil every 10, 000km.
  • The “synthetic” oil 5w40: This type of oil is really adapted to the recent Audi A6 engines, in actual fact, the protection of the engine will be optimum and the cold start too. It is consequently 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 replace.
