3 Oils, 3 Changes

There are three separate oil changes that periodically need to be performed on a BMW K1200LT.  There’s motor oil, transmission oil and final drive oil.  The motor oil service recommendation is every 6,000 miles with 20W50 while the transmission and final drive recommendations are every 12,000 miles with 90 weight GL5 gear oil.  So guess what?  I figured out some time ago that every other oil change all three oils get changed and today was one of those days.  The motor oil and the final drive oil are a snap to do.  But I hate doing the transmission oil.  It’s just that it’s a pain to do with parts to remove and hard to get to.  You usually end up getting the old oil on the floor because you can put the pan under it and have to fashion some sort of funnel.  Mind you, BMW probably sells a nice, expensive part just to do this.  Today I was prepared and put a very large piece of cardboard under the motorcycle and then put it up on the center stand.  I fashioned a funnel out of one my empty oil bottles lengthwise and about ½” tall so that it was flexible enough to bend and thin enough to be able to reach the recessed drain bolt.  This time it worked like a charm and I even get very little oil on the cardboard!

The motor oil would’ve been due during our upcoming trip and looking back on the mileage, the final drive and transmission probably right after the trip.  But I may as well get all of my laying on the garage floor done in one day and keep with the every other change philosophy.  I found no metal flakes on the magnetic drain plug for the final drive and only the dark sludge that’s expected.  The magnet on the transmission drain plug also had no metal flakes or shavings (even though the manual says a few are acceptable), again another thing good sign.  The gear oils were both still a dark golden color this time, yet another good sign.

Another service date out of the way!
