Not significantly much more fuel than a 337!

Its not GPH but MPG that counts.

Oh yes, and overhaul, maintenance and insurance.

A C172 only uses 10 gph to go what, 105 knots?
So maybe 10 mpg.

I have a friend who prattles on about Mooney fuel efficiency.

I have told him, "It is not polite to discuss fuel efficiency in the presence of twin owners..."
The TBM 960 uses a gallon a minute once it starts producing flight power. Altitude drives speed.
