But that said, I cant pass up the opportunity the facts above open up for me. I am starting a new venture. For the mere price of $19.95 plus S&H I want to offer a kit that essentially blocks these transmissions, thus assuring you that big BrotherMW, will never know that you prefer running grandma's castor oil in the motor and final drive.
Grandma always said castor oil was the best stuff you could use to smooth out your exhaust from your final drive areas, and she lived past 100!
The kit contains everything you see below, with detailed installation instructions.
You are not required to use BMW oil, omly oil that meets the correst viscosity and grades. There are many good quality oils that do this for less money.

The oil chart in my owner's manual for my '11 RT shows a couple of different weights recommended for what I feel is within some small variations in temperature. So, I go into my dealer and only said to the parts conter person- "I need BMW oil for my 2011 RT" to see what he would recommend. He opened the page on the computer screen and said: "WHOA! They sure have a few choices- like 5! What do you want to use?"
So much for expert advice or a definitive answer.
Bottom line is oil is good, no oil is no good.

I don't think it really matters much. At least, for certain, in the short run.
I just put the 15w 50 in my RT today. It's now sold under the Spectra name.
