  • The cold viscosity of engine oil for Mercedes Benz S Class (number in front of the letter “W”, which stands for “Winter”): This value will show the engine’s ability to start 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 weather conditions in which you drive your Mercedes Benz S Class.

Nevertheless, if you use your Mercedes Benz S Class 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 Mercedes Benz S Class

  • “Mineral” engine oils 15w40: They are named mineral oils because they are principally consisting of crude refined oil, which will give them maximum viscosity and therefore a thickness suitable for old engines that often consume oil. On the other hand, the truth 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 made up of several components that will improve its lifetime. It is thus suggested for a polyvalent use of its vehicle. Moreover, it favours a simpler cold start than a mineral oil. Nevertheless, you should make sure to change the oil every 10, 000km.
  • The “synthetic” oil 5w40: This kind of oil is really adapted to the recent Mercedes Benz S Class engines, in actual fact, 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 change.
