I am a new member.
I bought a new 2003 M5 this january, and i have been adding 5 full bottles of engine oil so far. The on-board screen said CHECK ENGINE OIL and the oil level was at bottom. I had a first service on 3,000 MI and the problem started after 4,000 or 5.000 MI. It seems to happen every 1,500 -2,000 MI, and ny car currently has 12,000 MI.
The Mckenna BMW and Nick Alexander BMW in California said it was quite normal for M5 and they simply added a full bottle of engime oil, and that was it.
Guys, please let me know if it's normal that happens often to other new M5?
I was suppecting that the piston sealings might be leaking.
Please let me know.
