Z4 m40i
Hello! My experience: 430i had to top up oil twice, I remember first time within the first 3000 miles. My z4 M40i as a clockwork 2500miles needed not only a top-up but a whole quarter. Still, the thing it changes from car to car, driving style (I drive pretty hard, I get the car in temp first) and never even considered break-in periods (even tho I have to admit I waited for at least 800miles to rev it high, maybe a reflex?). Should I bring it to BMW? Let's see what happens in the next 2500 miles. And BTW, the manual ask for 0W30 but since I'm in California I'm using 5W30... I doubt we'll get ever in the -10 (0W tolerance) or even -5 (5W tolerance).
If I wrote anything stupid feel free to call me out on it. Thanks
