Mein Auto: M Roadster/M3
AFAIK BMW doesn't make a 15W-40 synthetic. Their current oil for almost every BMW is a full synthetic 5W-30. The oil caps of the older cars say 15W-40, but that was a conventional oil.

I use the BMW 5W-30 in our Roadster, basically because with the BMW CCA discount, it is one of the cheapest full synthetics out there. I use Mobil 1 in two of our other cars (M3 LTW and Jeep Grand Cherokee). Castrol TWS 10W-60 in the E46 M3 because that is what is speced.

Most of our vehicles get the oil changed every year, as the mileage is not enough to trigger the change.
