By ALL MEANS, for *goodness sake, LISTEN to this bit of advice, if you
ignore EVERYTHING else. (not that you should ignore everything else; just
pay attention to this one-don't use something else "close" to the right oil)

I know for a fact that failure to use the __exact__ Rotax gearbox oil can
cause you to ruin the bottom end of your engine. *BTDT.
