    There is a lot of misinformation in this thread. One of the risks you take when you post a topic that has been beaten to death is you tend to only hear from people who don't know anything. Look at the thread GS FAQ at the top of the first page of the forum. 1) BMW oils are usually made by Spectro. They make good oils, but maybe not worth the price. 2) The specification for 1200 GS is 75-140 (or 90) in the trans and 75-90 GL-5 synthetic in the final drive. The reason NOT to put 140 oil in the final drive is that there is very little space there for oil to circulate. Too thick oil there can result in metal to metal contact, and it's all down hill after that. 3) The BMW specification for all years 1200 GS, is synthetic GL-5 in the final drive (and trans). Synthetic oil tends to hold up longer against sheer. Since your only putting 180 cc's in the FD and leaving it there for 12,000 miles you need synthetic. If you disbelieve any of this information, read some of the posts about final drive failures. That is in your future if you cut corners. Dave

    Redline Oils make a point of their oils being designed to be compatible with seals designed for use with petroleum products. I used Redline 75W-90 in my 1150GS final drive for the last 60,000km before the bearing needed replacement at 93,000km and the seal was still perfect (by the way, so was the cage).

    Well since someone already brought this up and I now have a new moto in the stable...

    Can some please tell me that I can keep life simple and just buy 75-90W synth for the tranny and FD in both my 1150GS and 1200RT Camhead????

    :ear


    If I gotta buy two different weights I know I'm going to eventually stick it in the wrong hole...:evil

    Very little space for the oil to circulate? Wow! I did not know that.

    Any good synthetic GL5 is fine. Change it regularly and you will not have a lubrication related failure.

    As for Red Line, I've used it in my Guzzi trans and bevel drive for many years with no issues. It actually improved shifting. I ran it in may RT trans also without any issues.

    I like to bring my 12v compressor to a pine forest and fill my tires with compressed nature air. Keeps them smelling clean and fresh.:wink:

    Good idea... Then you can let the pine scent out in your garage and keep living that ride over and over.

    I have been using Valvoline Dura Blend in my Airhead for 12 years and everything works great.


    the FD on my 2002 R1150 GS failed at 28K miles and I am having it rebuilt by the Rubber Chicken "Racing Garage. When I get it back I will be using the same Valvoline Synthetic blend in the tranny and the final drive.

    I bought a one litre bottle of the BMW recommended SAF XO from the BMW dealer for $24 bucks. This will give you five final drive changes. JVB recommends 180ML per change so that is about $5 bucks every set of Tourances at 8 to 10K miles for me. No big deal to me for a warranty approved fluid convieniently in stock. :D

    JVB hinted that you can buy the reusable ML dispenser bottle with the angled nozzle for $3.00 at Sally Beauty Supply, I bought two on sale for $1.98. Thanks JVB, I will buy your lunch if we ever meet.:nod

    But ask BMW for a single serving 200 ML bottle of the SAF XO and it is $9.00 :eek1 :huh:viking:bash:hung:topes

    Are you saying you think it is somewhat expensive?

    Wait...What??

    A detailed explanation is needed before I believe this statement. Space between what and what? Do you really think that there is anything inside the final drive housing that isn't completely covered in gear oil?

    No really, I want the science, the true high tech explanation behind this. AND I'm willing to keep an open mind if it is reasonable.

    Someone should instal a small camera and LED light in the final drive to document FD oil circulation (or lack thereof).

    Personally, and this is just me, since I'll be dropping $21,000++++ on my '13 GSA, then I'm gonna have NO problem at all buying the approved lubes recommended by the factory and sold by the dealers. Of course they're seriously and grossly overpriced, but so is everything else that BMW makes/sells. If (when) my tranny and/or FD goes boom, then at least they can't quibble over the lubes that were in it when it did.

    Again, just my opinion on what I plan to do. Not trying to say or even suggest that anybody else should do the same.
