> I was told by the service advisor that BMW consider 1 quart of oil every 1000 mi is normal. IS THAT TRUE?

Unfortunately, yes, this is true. The automtive industry, in general, sticks by that as the standard for "normal." Obviously this is ridiculous and simply a dodge to avoid warranty expenses, but it is accpeted practice by the auto companies.

P.S. Which brings up an interesting point to mention to your dealer.

If (a) one quart added per 1,000 miles is "normal," and (b) BMWs only require and oil change every 15,000 miles or so as BMW claims, then (c) between each oil "change" you will add about 15 quarts of oil, or the equivalent of about two complete oil changes! So why not just an oil filter change at 15,000 miles? After all, the contaminants are suspended in the oil, so as the oil burns off, one would assume the contaminates go out the exhaust as well (or form deposits in the combustion chamber/exhaust system). In either case, the contaminates are out the liquid oil that remains circulating.

Then watch the dealer scratch his head while he thinks about it.
