The specifications that differentiate engine oils for Audi A4?

.
The function of the engine oil in your Audi A4 is to lubricate your engine unit to ensure that all the gears in it can run smoothly , and to preserve the integrity of each of its elements. Furthermore, this oil, which will limit all friction, will have other features such as preventing corrosion, helping to dissipate heat in the engine unit and guaranteeing sealing . These oils can be bought in 5 litre cans. We will now look at the different criteria for purchasing engine oil for Audi A4 :

  • The cold viscosity of engine oil for Audi A4 (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 therefore up to you to change it to the temperature in which you drive your Audi A4.
  • The hot viscosity of the engine oil for Audi A4 (value following the “W”): Value between 20 and 60, it is important to remember 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. Nevertheless, if you use your Audi A4 in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The requirements : They are written on the back of the oil canister you can locate them such as “ACEA C1 – C4” or “VW 500. 01”, are only requirements of compatibility with different brands of cars, you have to check in the guidebook of your Audi A4 that the oil in question is suitable for your engine unit.
  • Oil brands: Please take note that the brand should have very little influence in your reasoning, there are enough objective specifications in the composition of motor oil for Audi A4 to avoid having to focus on a subjective qualifying measure such as the brand, some car manufacturers have partnerships and will encourage you on certain brands, but it is not required to follow these recommendations.

The different types of engine oil for your Audi A4

  • “Mineral” engine oils 15w40: They are named mineral oils because they are specifically consisting of crude refined oil, which will give them maximum viscosity and therefore a thickness suitable for old engines that often consume oil. However, the fact that they are natural will cause them to lose their lubricating properties more quickly, so it will be required 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 components that will boost its life expectancy. It is thus preferred for a polyvalent use of its car. Additionally, it favours a simpler cold start than a mineral oil. Nevertheless, you should make sure to replace the oil every 10, 000km.
  • The “synthetic” oil 5w40: This sort of oil is really adapted to the recent Audi A4 engines, obviously, the protection of the engine unit will be maximum and the cold start 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 reduce the frequency of their oil replace.
