 |
|
This MOGAS thread is has some great information. It looks like the greatest
threat is vapor lock which can be dealt with but what about Detonation? With
a 160hp O-320 my biggest concern was Detonation. But as long as I use 91-93
octane MOGAS, that does not seem to be the case. Is that a fair conclusion?

Scott:
Under the right conditions I can create Vapor Lock even with AvGas. The right
conditions seem to exist more in Texas than anywhere else. The only reason
why I say that is I have had more opponents of MoGas from their than anywhere
else. I have even had ALL the symptoms of vapor lock in a Piper Arrow with fuel
injection. I support MoGas and have seen better engine runs with MoGas than
AvGas. BUT! There will always be those in favor and those apposed.
With the addition of ethanol to our MoGas that should stop vapor lock, since
the vapor point and flash point are higher.
As for the O-320 with high compression pistons, YES stick with the 93 or
better octane. Ya know ... I have never seen 91 octane offered anywhere.
As for detonation, you can feel free to mix 100 LL AvGas with 93 MoGas ...
BUT! Never mix 93 MoGas with anything less than 93 or better.

This is a regional thing. 91 octane is the highest we have in my
town at 3,200 feet. I think the altitude is the reason.

At higher altitudes the octane level needed decreases. The engine operates
at a lower MP and has less cylinder pressure...it's like operating at part
throttle even on takeoff. We have 85 octane regular and 89 octane premium
in CO. Unfortunately they don't reduce the price.

"Unfortunately they don't reduce the price."
Actually, 85 octane should have more power than 87. The risk of detonation
is greater the lower the octane however.
