marvel in av gas

[mwood7800]

Does anyone add any mmo to there av gas, would it help mine from not wanting to shut off when hot?

It won't help with the run on problem...but it will lube the valve guides a little but AV gas already has properties that do that.

About 2oz. per 5gal. if you are running 93 octane pump gas works for me, as stated before, av gas has all ready got you covered!

I used Lucas Gas treatment in my super charge motor and it works really well.

I have run several diffrent fuels & mixtures thru my PE90:
100LL Av-Gas
93-94 oct blended w/ Av-Gas
89 oct blended w/ Av-Gas
93 w/ MMO
89 w/MMO
as far as I can tell they all run about the same, WITH an edge going to Av-Gas: the 100LL did seem to run a bit cooler, but seemed harder to start after a long hard run.
The PE90 isn't exactly a high compression engine, and the only time of the year when we have comparable weather to FL is in July.
I'm going to try the Lucas additive whenever I stumble onto a bottle of it, I have used several of their other products with success.
