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.

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.

Is that 13 gph based on tach or hobbs?

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.

My 67 burned between 11.5 and 13 depending on how hard I was pushing it.
I typically ran 22 square at 6-8,000 feet.

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

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

I'm not sure that's the right one, but look around. You might find what
you're looking for.

My 182R (230Hp/O-470-U, factory reman) burns 53 litres/hr (~14.0 US gal/hr)
at 23/2350 at 3500'. Down to 48 l/hr (12.68 US gal/hr) at 21/2200.
Consistently. Measured by a very accurate JPI fuel flow meter. Top-up is
within 1 or 2 litres of JPI reading, out of 250/260 litres. Everyone tells
me it should be lower..... It is at 6500', with settings 20/2350 (WOFO) ~
48l/hr.

Our 1979 C182RG burns on average 13.5 gph in cruise flight (based on our JPI
EDM-800)

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

-jav

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

This is based on my 1970 N model with an O470R engine thats
about 100 hours beyond TBO (1500hr on R).
I have plugged in to my various flight planning programs pretty
close to what the manual says, and on refuel rarely off by a
couple gallons. I use one of those universal dipsticks and I
find that at the lower values is where I find the most errors.
Anyway, below 8,000' it seems to be around 12.5-13gph and
recently back east staying below 4,000' it was at least 13gph.
Where it shines is heading west (well, I guess direction doesn't
matter)and in the O2 altitudes, I'll get 10 to 10.5. This is always
at full throttle and 2400-2450 RPM, trueing out at 130k with the
wheel pants on, 127k with them off. EGT around 1550, burn
around a quart of oil every 13-15 hours. Although I'd love the
room of a 206/PA32, I've been very happy with this engine
and airplane.

I have a 1978 182Q with an 0-470-U (new ECI cylinders 75 hours ago) and I
flight plan 137kts @ 8,000 feet. 22" MP @ 2,200 rpm and it burns just about 12
gph. At lower altitudes and lower power settings, I burn about 11 gph. At
faster cruise power in the lower than 6,000 foot range, I burn about 13 gallons
or so.

I checked out both types prior to purchasing and these few items put me on the
side of the 182.

1. Doors on both sides (under the wing) which keeps you in the shade and out
of the rain during loading.
2. If I ever had an off airport landing and I nosed over, I can open the doors
to get out of the 182. In the 6/300 you may get trapped.
3. I rarely need more than 3 passenger capacity.

I learned to fly in Warriors (Low wing lover) and really wanted an
Archer/Arrow/ or Six...but for the money and performance I chose the 182. (It
took a long time to find the right one though)

Good Luck and whatever decision you make, it will cost more than you expected.

Jim, is that TAS or IAS? Seems low for TAS at that altitude.

I think the power settings he mentioned are equivalent to about 60%
power, so those speeds seem OK, no?

-jav

TAS. And a correction. That's 20" and 2200 RPM, not 2300. I didn't notice
that typo until I went back to see why you might think this a bit low.
