Evening the gentlemen (and ladies), the previous owner of my new used E91 has really exhausted it with the time for the oil change and drove 30000km and 4 years without oil change. Anyway, nothing is noted in the checkbook. The new oil is now 1000km in. Question: Should I change this right away to compensate for the long phase before or aim for a normal interval of 10000km? In total the car has 74,000km down. Petrol with 143hp.
