Last year my M3W started seeping oil into the sump. So if it sits more than a couple of weeks, I have about 1.5 quarts in the sump. if I start it, I end up blowing a lot of burnt oil smoke ut the mufflers....

so added to the routine... drain the d@mn sump before start up and return the oil to the tank
