While BMW says no break in is required and fills with synthetic oil from the get-go for most of their cars they do recommend " break in oil" for the M cars, changing to synthetic at 1,200 miles. I also understand that BMW says that consuming a quart of oil every 750 miles is still " Normal".
Has anyone experienced high oil usage?
I am thinking of draining the synthetic as soon as I get my car (leaving the filter in place) and replacing it with Dino oil for the first 1,500 miles. Then I would change the filter and change back to synthetic oil. The idea would be to help the rings seat better.
What do you think?
