M40i
Have enough mileage now 2200 to see if there is an oil useage issue. The computer thingie shows FULL when I ran the test this morning. Hate not having a simple dip stick.
Usage has been. Break-in to 1200 miles followed BMW's recommendation. 1200 to 2200 mostly quick suburban driving (Sport+ stick left, Stability off) with about a dozen hard runs to get some Draggy times.
One long trip 220+ miles each way of fast non-stop interstate runs.
