I agree with this. I've even run race motors of different types low deliberately to help with oil control.
Run it at the low side of the sight glass deliberately and see what happens.
Also, get in the habit of letting your bike sit on the centerstand overnight and check after it cools down so you get reproducible readings.
Lemon Laws in my state cover only light trucks and cars. Message is sent to you as to what State I'm in
When I first went to the dealer I was topping the oil off to the top of the sight glass. That way I didn't have to top off the oil every freaking day or every other day. Since then the dealer has been doing the oil consumption tests. This is where I drive the bike to the dealer (an hour away) when the light comes on or when it gets low.
They measure how much oil goes into the bike and record the mileage and find out how much oil it has burned. Now obviously when the light is on and steady I record the mileage myself and fill the oil to the middle of the sight glass. If I top off the oil to the top of the sight glass or only go halfway it doesn't change the rate of consumption.
Also the bike goes on the center stand at night regardless if I'm on or off road. It only sits on the side stand while at work, if I go in somewhere to grab a bite to eat and things like that.
I live in Michigan. We have lemon laws here. In fact, I am about to take my truck in for the same problem, the fourth time. I am contemplating asking for them to terminate my lease (I love the truck, hate the payment). Regardless, if you do not get the bike fixed, it cannot be called a lemon, from a legal standpoint anyway.
For the OP, take the bike to a different BMW dealer. Dealers are like people; some are good, some are not so much. Tell them the situation, and have compression and lead down checks performed. Or even better, don't mention the oil, but play half stupid, and tell them you would like these tests performed, just for peace of mind. Then bring up the oil issue.

I see where you're coming from on this but if I find a good dealer and explain the whole situation wouldn't they pay more attention to detail and document everything? Just my thoughts behind this. Are there any dealers in the midwest anyone recommends? Or are there any outstanding dealers anywhere I have some vacation time to burn up. I've heard decent things about Gateway BMW in St Louis from a lot of riders on ADVrider and various rally's I've been to.
If it is not far out of your way, Detroit BMW has an excellent mechanic. Don is top notch.

He did say that he ran it until the light came on. That sounds lower than the minimum amount. Otherwise, I agree with your thought. That is how I regulate the oil level on my airheads albeit with a dip stick. No one has mentioned the type of oil used. Never having owned a new BMW, I may be off base but was the break-in done with petroleum base and if you switched to synthetic, when? If you're running synthetic, try switching to petroleum. Maybe.....
Not just good, but good enough.
Not knowing your location, it is rather difficult to suggest an alternate dealer.
Have you asked your current dealer to do compression and leak down tests?
I gave them the bike and asked them to do a compression and a leak down test. They did the compression test, it came back good. They didn't even bother with the leak down test. The left side showed 225LBS and the Right showed 215LBS according to them. I've bought a compression tester and I am about to double check the results. According to the research I have been able to find online
Compression Test Pressure for my bike is as follows. Good = 10 bar or greater; Normal is 8.5 to 10.0 bar ; poor is 8.5 bar or lower.
Oil can get into the combustion chamber by blowing past the rings OR by being sucked in on the intake stroke by way of faulty or MISSING valve stem seals. Valve stem seal problems won't show up on a compression test.

Valve stem seals would have to me missing for this bike to use that much oil.
Here is a different thought. You have always used BMW dino oil. Next oil change, try something different. I know it should not make any difference, but I have had engines in the past that burned more or leaked more of certain oils than others. It is worth a try.

It is possible that they ARE missing. I have taken apart car engines to replace head gaskets and found that the factory left one of them out. This happened on Jeep 3.7 and Dodge 4.7 engines. The machining was so good that they sometimes lasted 50,000 miles with a missing head gasket. A co-worker has a brand new Honda CR-V and it had an oil consumtion problem that turned out to be missing valve stem seals on one cylinder. BMW is not immune to human error in the manufacturing process. It's easy enough to check by pulling the valve covers. If it were mine I would bull the spark plugs out and take the valve covers off, then use a smoke machine to put smoke in the crankcase, if it leaks out the spark plug holes, rings, if it comes out of the valve seals then ther's the problem. I do realize however that not everyone has acces to a smoke machine ( every car dealer in the U.S. has one by now).
