on a Cessna 180. What are you Cessna 180 owners getting? What do you normally fight plan on average per hour with an engine properly working on floats?

They have different engines, are you looking for one engine in particular?

As a general rule of thumb. You can expect 1gallon per hour/ 20 hp. So if your C-180 produces 230 hp, you can expect and flight plan for 11.5 gph. Likewise, if you operate a C-185/206 at 300 hp, your looking at 15 gph.
Hope this is helpful. ( 1 gallon/ 20 hp/ hr.)

Going back a while....
0470, 23 square, full rich, could get up to 14 gallons/ hr.
Lower power, very lean, down to 10, so average with reasonable engine management , 12.
