The criteria that differentiate engine oils for BMW i3?

.
The function of the engine oil in your BMW i3 is to lubricate your engine to make certain that all the gears in it can run efficiently , and to preserve the integrity of each of its elements. In addition, this oil, which will limit all friction, will have other features such as preventing corrosion, helping to dissipate heat in the engine and guaranteeing sealing . These oils can be bought in 5 litre cans. We will now check out the different criteria for purchasing engine oil for BMW i3 :

  • The cold viscosity of engine oil for BMW i3 (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 change it to the temperature in which you drive your BMW i3.
  • The hot viscosity of the engine oil for BMW i3 (value following the “W”): Value between 20 and 60, it is necessary 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 BMW i3 in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The specifications : They are created on the back of the oil canister you can locate them such as “ACEA C1 – C4” or “VW 500. 01”, are only specifications of compatibility with different brands of cars, you have to check in the book of your BMW i3 that the oil in question is appropriate for your engine.
  • Oil brands: Please take note that the brand should have very little effect in your reasoning, there are enough objective criteria in the composition of motor oil for BMW i3 to avoid having to focus on a subjective qualifying measure such as the brand, some car producers have partnerships and will advise you on certain brands, but it is not necessary to follow these recommendations.

The different types of engine oil for your BMW i3

  • “Mineral” engine oils 15w40: They are known as mineral oils because they are mainly consisting of crude refined oil, which will give them maximum viscosity and consequently a thickness suitable for old engines that often consume oil. On the other hand, the truth that they are natural will bring about them to lose their lubricating properties more fairly 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 several elements that will improve its lifespan. It is thus recommended for a polyvalent use of its car. Additionally, it favours a simpler cold start than a mineral oil. However, you should make sure to change the oil every 10, 000km.
  • The “synthetic” oil 5w40: This sort of oil is really adapted to the recent BMW i3 engines, obviously, the protection of the engine will be ideal 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 reduce the frequency of their oil change.
