c182 fuel burn

Can someone tell me what the fuel burn numbers are on a typical older c182
with the Continental 230hp carbed engine. I am trying to do a comparison
with a Cherokee 6/300 and can't find numbers for the C182.
Thanks, RT

The 182 (1963 C model I think) in the Bay Area Aero Club bills its
members at a wet rate based on a 13 Gpm fuel burn. This burn rate is
based on actual usage and is surveryed quarterly. I cant account for how
much of this is training (and richer mixtures) versus XC (and hopefully
leaner mixtures). The aircraft has been in the club for about 2 years,
and newsletters may show some variation in the fuel burn.

Is that 13 gph based on tach or hobbs?

Hobbs.. Good question and sorry I didnt specify earlier. Maybe it wasnt
much in the way of good info after all.

Rule of thumb for piston engines: divide rated HP by 18 to get cruise
fuel flow. Assumes about 75% power and proper leaning.
IE, 230 HP is about 12.7 gal/hr.

FWIW
180 hp M20C (carb'ed) run 600 hrs mostly x-c at 75% 9.5-10 gph cruise
trips of 1.5-2.5 hours typical
Flight Fuel Flow average 9.1 gph (total fuel / flt time) as measured
by Garmin 196
Tach Fuel Flow average 8.5 gph (total fuel / total tach)as measured by
Horizon electronic tach
No Hobbes to compare
YMMV

Depends entirely on how hard you run the engine. I prefer 20" and 2300 RPM
(makes for a very smooth ride) and get just under 11 gph by the clock.

My experience is consistent with this. I've been keeping track of fuel burn
for the last 2 years since getting the airplane (a '67 but with the O470-U
engine), and my average is 11.3 per tach hour. Most of my cross-country
flights are at relatively high altitudes (10 to 12K) where MP is down to 19
to 20 inches at WOT.

What average TAS do you get at, say, 7500' with those settings?

I usually expect to see 112-115 knots depending on temperature and loading.
