No, no, no! You fellows lack the proper reverence towards fine German engineering.
First, you must do the oil change inside, in your drawing room, over your wife's best Persian carpet. That is the only proper milieu.
Next, the bike must be standing upright and you must perform the oil change standing on your knees beside it, facing Germany. That is the only proper attitude.
Magical incantations are free. But you'd better lift the bike when you turn the wheel, not just drag it against the carpet, or you'll be in the divorce courts. And you'd better pull out the 25ml of air or the thing will spit all over the carpet, result ditto.
Then you must take a ceremonious ride along the most beautiful avenue of trees you know. I mean, leaving the bike standing, draining, against the wall of a pub! It could only happen Down Under*.
