Hello Aero Nut,

Yes, I tried the 80% Coleman Stove Fuel and 20% Methanol. This mixture simple will not combine. Even with the use of Amsoil Saber Synthetic oil added to the mixture.

I have been following you suggestion on “Engine Conversions” for a couple of years, and you comments encouraged me to give this a gas/methanol mixture a try.

I setup a several jars and dug out my plastic syringes to measure the components very accurately.

First I tried the 80gas/20methenol. It separated into two distinct layers. I could shake up the mixture but it would separate out with in 1 minute.

I then tried a whole series of mixtures using simple ratios starting at 90% gas to 10% methanol up to the opposite end of the spectrum to 90% methanol to 10% gas.

The experiment showed that you can make a mixture that is soluble at a ratio of approximately 15% Stove fuel to 85% methanol. The Methanol will not absorb any more gas. It will begin to separate out if the ratio is increased. The other mixture that you suggest is not possible. Since the gas rejects the methanol.

Next I did the same set of experiments using the Amsoil to see if the oil will allow the mixture to stay mixed. I did not see any appreciable improvement with the addition of this type of oil

I suspect that Klotz KL 100 or KL200 my make a noticeable improvement, but after investigating methanol, I have come to the conclusion that E85 (which is a mixture of ethanol and gas is possible but the combination of Methanol and gas is not possible with an mixture greater that 85% Methanol and 15% gas.

I have read that you are a Chemist, could you please advise?

I was so excited by the possibility of using the 80gas/20methonal that I did a bit of machine work as posted in the link:

So like you I was looking for a way to run my lawn and garden Airforce without a magneto, or spark ignition and not have to find a new carb.

I tried to run the mixture of 85% Methanol and 15% gas but the engine will only run if I have the choke set up to ½ open and it is not possible to meter this mixture with the stock carb.

I’m confused by your suggestion to give 80%gas and 20% Methanol a try. I don’t understand how you could keep this mixture suspended. I watched a clear fuel line while I tried to feed this mixture into the engine. The fuel separated into separate balls of gas or Methanol. It was unworkable for me. Perhaps I missed something in one of your threads.

Again, I applaud your effort and the work you have done to promote this experiment. I would be happy to try E-85, but we don’t have it here in Eugene Oregon yet. You can still breath the air here.

Please get a glass jar and make this mixture of 80 gas/20 methanol. I suspect the gas is polar and the Methanol molecule is non-polar, thus Methanol is capable of attaching to gas up to the point of saturation of point, which appears to be approximately 15%. Ethanol having a different structure must be able to bond with polar molecules at a much higher ratio.

Please advise,

Respectfully,

Poppy.
