Break in and oil consumption
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? |

If you do that you will possibly invalidate the warranty, if for example the engine had a problem while that dino oil is in it you would have an issue.
I would follow the BMW recommendation. They make thousands/millions of cars and do massive amounts of testing and likely know what's best for a new car/new engine regarding performance/longlevity and reliability. IMO of course |

I bought a demo model, 4000km on the clock, 5000km later it has not used any oil, 2.0D x drive. No break in procedure would have been used, and no issues since I had it.

A quart every 750 miles !?!?! No way. Perhaps every 7500 miles. In all my years, my BMWs have never burnt that much oil.
I think switching to dino for break-in is overkill. When was the last time you heard of someone retiring a BMW due to an engine failure related to oil lubrication? |
