Fuel Prices and their Effect on Your Flying

That's one way to to do it. Bonanza are a lot more fuel efficient than
a 182.

I just had a trip last weekend in my 75 AA5. 420nm buring 27.58gal of
autogas, about 15.2 nmpg. That's very good for a production 4-seater.

TN B36 (IO-550): 418nm (Montrose-Lincoln, NE), 185kts, 19kt tailwind, 12,500
feet, 32.5 gallons 100LL, 60 LOP; TT 2hrs 19min.

Ugh: Kearney, not Lincoln.

That depends on whether there's an airport selling mogas near your home
base. For example there're quite a few in midwest, right in the corn
country: http://www.chouby.com/apps/autogas.html

The best "mod" you can get to make fuel cost more bearable is the
autogas STC, if you're lucky enough to own a model that can get the
STC, and you can get ethanol free autogas.


How great is that mod when you need to get 30-40 gallons into the plane?

Do you land at a gas station? G

Even 20 is a lot to carry around in portable containers.

Yes a TCM 200 hp IO-360-A3B6D with no GAMI's. I usually cruise 5-6k 24
squared and 20-30 LOP.

penny Save gas, but more importantly, your engine. (see below)


I have found that in cruise I can save many gallons-per-hour by twisting
the red knob until the EGT's peak and then get to 10-20 degrees on the
other side of peak temperatures. I know that this will not work for
everyone but for my IO-360 it gives me a cool, smooth running engine that
is only drinking 9.5 GPH.


At what MP? Throttle setting? Altitude?

http://www.avweb.com/news/columns/182045-1.html

Yes, cool and smooth...but possibly with excessive internal pressure.

Red Box = No Fly Zone
At and below about 60% power, there is no red box.
At about 65% power, 100ºF ROP to Peak.
At about 70%, 125ºF ROP to 25ºF LOP.
At about 75%, 180ºF ROP to 40ºF LOP.
At about 80%, 200ºF ROP to 60ºF LOP

Have higher fuel prices forced you to adjust your operations?


Fuel here is $4.15, up from $3.45 so it translates to about $11 more an
hour. Considering our hourly DOC & Reserve is around $135 an hour, $11 is
minor.

We did cancel a optional trip to the "Big City" for shopping.


I'm sure that over the years when fuel prices have peaked, folks have made
changes, but since I am a new owner (working on our second year) it is my
first experience at spiking prices. So what say you?


LOP is your best bet. IIRC, the Mooney is running a TCM? If so, GAMIjectors.

This is probably why many of us don't see the advantage. G

How do you get 30.5" at 12.5K w/o a turbo?

I have a 180hp (C/S prop) C-172F with the lyc O-360 and I burn and plan
on 9 gph. Why are you at 11? I run 2300 rpm and 22". I believe that give
me 9 gph.

I'm burning a lot less gas, approx 40%, than when I had my 182.


Amen.

Would you mind talking some sense into my partner? We have a perfect
opportunity to buy a F33 from a friend in the next hangar over. Pristine
aircraft, casual sale (so no tax liability here in NJ), just needs some
avionics work. It does 178KTAS on ~15GPH, while we burn 11GPH in the
172/180HP doing 115KTAS on a good day. Ugh. My kingdom for a little
common sense.

I alter my weekly commute to include a fuel stop at an airport where fuel
is about $1.60 (US) cheaper per gallon than either my home airport or my
destination airport. Once there, I fill the Bonanza's mains and tip tanks
to capacity. I also reduced my Angel Flights by about 25%.

I have concidered GAMI's but since I get my engine to run smooth and
cool LOP I didn't think the cost would be worth it. On the Mooney
owners list we have some very knowledgable folks from GAMI that
participate in the lists and have told me that 20-30 LOP at 70% will be
no detonation issue at all...

In calculating off the top of my head, you're running about 70% (your's is
200 HP?); see the chart below.

Have you considered GAMI's?

Try this: 12.5K, 185kts, 14.5gph (30.5"/2350 RPM); smooth as silk, even at
idle.
