I have seen this topic has been a bag of worms on other forums, so instead of starting another can of worms thread here by asking IF it works,
I'm going to tell you the answer. It DOES work.
I tried today, with a mixture of roughly 60% pump gas 98 octane, 30% glow fuel (coolpower 15% nitro, synthetic oil. the first and best thing i had at hand) and 10% mineral two stroke oil.
the engine i tried it with is a brand new ASP 91 four-stroke, mounted in a very generic (chinese) .40 size low-wing sports trainer.
After shaking the mixture was a nasty brown color, but the mixture appeared homogenous. Wich indicates that the ingredients did mix well.
the nasty color was probably due to green fuel being mixed with red oil.
At the end of the flying day, the mixture still appeared homogenous.
Differences I found was:
* Much longer flight times (increased from 12 minutes to 22 minutes)
* Much better fuel economy, gas is cheaper than glowfuel, and consumption is lower.
* Much leaner needle setting required.
* Maybe slightly less powerful, if any difference at all.
* Hotter running motor.
My motive for trying was that I had very little fuel and I WILL fly, my way or the highway :-)
Long term effects like changes in engine wear would at this point be unknown for me.
But I don't really care about that either, with the glow fuel costs, I would only have to fly up 8 liters (2 gallons) of this stuff before fuel savings has risen over the value of the engine.
Conclusion is that I will continue doing this.
Only change I will do is to mix gas-fuel-oil in ratios 45-45-10 instead of 60-30-10 in order to make the needle adjustment easier.
With high gas content in the fuel, the motor will have to run very lean and become hard to adjust (glow carbs isn't made to run that lean).
Please feel free to discuss my experiment, but don't say its not possible, like so many other threads do. Its possible, I have done it.
