So what sort of fuel burn are the allisons that are in the 300HP range? I am
sure turbine power is the way to go above 400hp since those planes are usually
distance driven with the fuel capacity tailored as such. That is also when
piston power loses reliability(except LARGE radials) I think we are getting some
experimentals that are getting big enough to play there. I would love to get
something beside a 540 or M-14 for my plane but the LS1 chevy V8 is the leader
for me as far as alternitive power. Turbine dreams but chevy check book and
fuel storage.

Hi, new to the list and wondering if anyone is using auto fuel in the 160
HP Lycoming 0-320 engines with 8.5 to 1 comp ratios when installed in the
low wing aircraft?

Roswell, NM

Vic,
This is coming strictly from what is approved by a STC for certified
aircraft. The Lycoming
high compression engines i.e.. 160 and 200 HP engines are not approved for
auto fuel while the
150 and 180 LC engines are.
I am sure there are people out in the field using it. I didn't mention the
540 engine group because
it covers a wide range of HP and I'm not sure which ones are considered high
compression and
which are not.
Right now I'm paying $2.25 for 100 octane and it isn't worth the hassle as
91 oct. is $1.65. Also
every carb that I've torn down that was using auto fuel has had some degree
of corroision in the bowl.

There is an STC to do so. I don't remember who owns it. In automobile
engines, 92 octane mogas can be used at compressions up to 11.2:1 if the
ratio is kept rich enough and the ignition is somewhat retarded.

All that aside, I have a Lycoming that has 9.0:1 compression. I wouldn't
dream of running mogas in it.
