If you check the oil dipstick with the engine cold and the engine off and you realize that the level is a bit low, we can top up.
It will be sufficient to pour a little oil from the inspection plug located in the upper part of the engine.
If, on the other hand, after a year and at least 20,000 km we want to completely replace the oil contained in the engine, we will need to take the car over a mechanic's hole.
In fact, in order to completely empty the oil, the oil contained in the engine must be released through the oil pan located in the lower part of the engine.
You can then pour in the new oil from the inspection cap located in the upper part of the engine.
Then check the level with the dipstick.

Some are used to make the oil more or less thick, others are anti-corrosive, anti-foam and anti-rust.
