Hallo newyork,
I just changed engine oil, oil filter, polen filter and diesel filter, I made 1week ago inspection, normal I change every year all filters and engine oil or until 10.000km. Only for transmission I want to know if it’s better to change regular or not to change at all. I want to keep the car in good condition because until now I didn’t had problems with the car and I want to take care in the future.
