For the first time on my 2000 M5 (I have had it since 02) a low oil level warning came up on the check control. Within 20 miles, I had checked the level, which was right under the minimum, and had topped it off with a liter of 10w-60 from the dealer, bringing it to full.

Do these cars burn oil? Is this a cosmic warning sign? I have always changed the oil when service is requested by the computer, etc.

Thanks for any advice.
