Peanut oil

It's weird how castor wi stay in solution and peanut wi no.

I feel like I read that nitro helps keep oil/methanol mixed. No guarantee this is fact...just something I *think* I read along the way.

One of the unique properties of caster oil is it will mix with alcohol and not separate. Alcohol in gasoline will separate in a few months, add humidity and it gets worse. It’s called phase separation and is a problem down here.

I added a couple percent of acetone and it did not help with any of the cooking oils mixing. Maybe nitro will help. I did not really want to use nitro as it was a budget idea/test. I have a bit of nitro left that I could test it with sometime.

Ad gaz Line antifreeze it help Against the separation several brands of fuel use additives easy to measure their actual percentage easy add a little water this work wit gaz Take a graduated container with measurements of Gas then add water Measure the water beforehand Alcohol with additives separates with water It’s called phase separation After the excess that appears in the water mixture is the percentage of additive wit diesel its Difrent They are different additive To prevent against mold

Is there something else besides methanol in gas line antifreeze? I thought it was mostly methanol (or ethanol) that abosrbs the water in the fuel, and then mixes with the fuel?

I thought that is how "alcohol" holds water in suspension in fuels...well, until it can no longer absorb water, and that is what I understand is the "phase" issue causing alcohol to drop out of fuel.

Aspeed, I've seen your work on RCG's 1/2A forum. So I'll take what you indicate as coming from someone well versed in glow fuels and hotrodding these little engines. Please continue and share your experiences here.

CB, now that you mention it, maybe that is the component that I was thinking about...castor readily mixing with methanol, and thus is the carrier/emulsifier for synthetic oil in methanol.

Since Castor works so well and is still readily available, what seems to be the problem? Even if forced to use an alternative to Castor, I think I'd take my chances with full synth before dabbling in using cooking oils.

Mostly cost savings.  Castor is about $10 a litre here, and Klotz synthetic would be more, and is hard to find.  $2 a litre would be much better, with methanol from the hardware store @ $11 a gallon.  That would be fine for a larger engine, and a cheaper source of methanol might be found as well.  I know of a place in Detroit that has reasonably priced castor oil, but we are not able to cross the border.  Fuel from the LHS is about $40.  Cost is really not an issue for me, and the wife doesn't care but I like to experiment sometimes.  Ucon Soybean? had been used at one time.  I found that it ran hot and stained the aluminum
