Hello together! Since I drive the high-performance combination of 2.2 TiD and automatic I wanted to ask if I should allow an oil change to the automatic transmission after a certain time … I now have 124,000 km off. Since it looks like I will still be friends with my vehicle for a long time, I wanted to do something for durability… The engine oil is changed by me every 15,000 km (according to Saab all 30,000) and there soon again an oil change a What do the specialists say and what amount do I have to reckon with??
