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

Third I am now learning and practicing everything I can about Lean of Peak
(LOP) operations in order to save money on fuel.


http://www.advancedpilot.com/index.html - expensive ($1000), but worth every
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?

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.
