Changed the oil this past week as part of the 12,000-mile maintenance. Everything went smoothly. This was the second time doing it for me so it went pretty quickly. The process is to remove the bash plate, loosen the drain plug a bit (makes it easier to remove later when the engine is warm), remove the left side cover, then warm up the engine for a bit. Loosen the top drainplug a little, then remove the top oil container thing, then fully remove the drainplug and tilt the container to empty out the oil into a jug or something. After that is done, replace the drainplug and put the top oil container back into place. Next, remove the bottom drain plug and empty out the oil. Clean the drainplug and any debris that the magnet may have trapped. Put a new crush washer on, and tighten the drainplug. Next, remove the front sprocket cover, and get ready to remove the oil filter cover which means to make sure and have your makeshift funnel ready. BMW will sell you the funnel for $65, but I opted for the beercan method (see photo above). Remove the old oil filter and replace with a new one (put a little fresh oil on the rubber seal first). Put a new gasket on the cover, and put it back together. Next put 2 liters of oil in the top, then let the engine run for 30 seconds. Add .3 more liters. Replace bash plate and side cover and you’re done. Easy peasy!
In addition to the oil change, I bled the brakes and put in some fresh DOT-4 brake fluid. Now the brake action feels a lot more solid.
