What brand of oil should I change for Mercedes-Benz 320 engine? And what brand of oil is the gearbox? How much does it cost to change it yourself?

It is best to use synthetic oil of SM 5W40 grade; The gearbox is divided into manual gear and automatic gear. The oil used is not engine oil, but manual gear oil and automatic transmission oil, but the brand is the brand mentioned above. There is a problem if the new 320 is replaced by itself: the oil change odometer needs to be reset and matched by the special computer in the maintenance station. If it is automatic, a special replacement machine is needed to replace the automatic transmission oil. Otherwise, only 30% of the old oil flowing out naturally can be discharged, and 70% of the old oil inside cannot flow out naturally, and the purpose of replacement cannot be achieved. If you spend more than 200 to 400 oil, 100 manual transmission oil and 300-500 automatic transmission oil (8L- 12L is required).

This answer is painful.
