BMW NA gace me an "answer."
Well, I promised I would share whatever answer BMW would provide on this subject. Looking at the exchange below, read my letter the bottom and you will see that instead of accusing a dealer of making a mistake, which I thought might bias the reply, I implied that I installed the 20W-50 and later found the manual to not include that viscosity oil. I had hoped they would tell me I was ok or that I was wrong. Either way, I could have known what to do. The response, however, provides no information that I find helpful.

Subject: BMW R1200RT 600 mile service oil question
Thank you for reading this email. My question is, do you recommend I use BMW 20W-50 (non-synthetic) oil in my new 2012 BMW R1200RT motorcycle for its 600 mile service? The riders manual does not list that oil for my motorcycle.
If that viscosity oil is recommended for the 2012 R1200RT, why isn't it listed in the owner's guide/ Is there an update from BMW that includes that oil for my motorcycle?
If that oil is not recommended or approved, and I have already installed it, should I go ahead and change it again? The operating temperatures where I live are between 20F and 70F for the next four months, which means a cold start below 40 degrees each day.
Thank you very much for taking the time to answer my questions. I want to treat my motorcycle in the best possible way and hope that i haven't made a serious mistake in installing an unapproved oil.
So I asked my dealer about the oil not meeting the specs in the manual and his reply was:
[B]20w50 is fine for the temperatures we ride in in the South. BMW has ran 20w50 in their bike for sometime now and this weight is OK for your motorcycles.
I will contact our rep just to see if I can get some clarity on the changes to the owners manual for you.[/B]
Ah well. Almost sounds like an oil thread. I will follow the specific oil and viscosity recommendations in the manual and change it myself in the future.
