Fuel Consumption: 0-200 vs 912s

[Monocock]

All

There is an ongoing debate about the fuel efficiency benefits of either of these powerplants on one of our UK flying forums. Avgas has hit the equivalent of $13 per gallon here in the UK and MoGas is $9 !!!!!

Please can anybody give me some reliable data on fuel consumption in the same airframe? ie I use 19 lph in my Mk 5 with a 912s. Is anyone out there using an 0-200 in a Mk 5 and if so, what is the consumption? A Mk 7 comparison would be fine too - as long as they are comparable airframes. Thinking about it, a Mk 7 0-200 fuel burn could be compared to mine as there is little difference in airframe.

Thanks in advance
