The best figures I've seen quoted for the o-200 give about 23 litres

Even with the lower cost of avgas in the US, the difference must be
enormous.
For reference, 10 extra litres per hour means $15.30 extra per hour
here in Australia.

Gregg,

I've no experience with the Rotax, but A LOT with the O-200. 20 litres
per hour is a very realistic number at a high cruise setting. I suspect
the 13 per our figure you're referencing is at a somewhat conservative
power level. Also, don't forget that the average O-200 will go about
1000 hours longer before overhaul than the 912.

My 912 is rated 1500 hours between overhaul
and the best info I can find for the O-200
is 1800 hours. Am I missing something?
