640i oil consumption

Jon D · 08-01-2017, 02:02 PM

I have accumulated almost 5k miles since new and the oil level indicator still indicates max. Ok, I took care to run it in under varying loads and RPMs but I would have expected some oil usage by now.
I'm not a fan of electic sensor level measurement and my mistrust was vindicated when it failed on my F10 535d but at least I had a good old-fashioned dipstick to fall back on.
I'd be grateful for fellow owners views - thanks.

Why would you expect oil consumption after 5k miles? My last N55 engine drank a quart about every 6 months+ and it was an older car. My current N55 (640) hasn't needed additional oil since I purchased it last December.

My previous 640i used about 1 litre per 10k miles and I didn't consider that excessive. Just wish there was a dipstick to verify.
