I am curious to know who's here makes own fuel? and you don't mind I would like to know your experience. How long you have been making it, what type of oil do you use and what percentage of Nitro are you using, and what size and type of engine are you using it on?

I leave it to the experts.....They have the proper equipment/facilities to make consistent batches each time.....from gallon to gallon.

Is good glow fuel that hard to get nowadays? I know it's expensive, but are there that few companies that distribute it?

And, what's the difference between quality fixed wing aircraft fuel and quality heli fuel?

The oil/oil content?

There's plenty of people flying fixed wing "nitro" aircraft where I fly....

I cannot argue with that, but it is fun to brew your own fuel when you can get everything you need local at low cost, just like building an Heli and watch it fly.... Lol..

Yes the fuel is extremely expensive, and it takes longer when I order it from my local shop, unless I decide to drive about two hours which brigs up the cost anyway.

The difference with the fixed wing is mostly the oil content.
The oil content should be about 18-23%, I brew mine with 23% oil content.

I have made fuel many times. Best to do it in 4 to 5 gal batches. Then dump into 1Gallon jugs. That way it is consistent for multiple gallons. I have had the best performance using Klotz heliglow oil. I blend at 20% oil and 20% nitro for 90 size and up. 25% nitro and 21% oil on smaller motors. Never needed 30% nitro with slightly lower oil content. Also keeps the model cleaner.

Percentages based on volume or weight ?

To be honest I like 30% Nitro only because I am used to it, however I will try 25% just to see if I like it. As for the batches, I think the I might have contaminated Methanol, so I ordered Hydrometer to test the remaining of methanol that I have left. On my first test I did use Klotz and it seemed to run fine, I did not have engine quit not even once and the transition was smooth. When I changed oil (Thor), that's when I have noticed the change in performance. Nonetheless, I think I might have some water in methanol, will see after the test.

The percentage is based on the volume.

they make water trap funnels for gasoline. Not sure if it will help on Methanol.

No it won't help for a simple chemistry reason: methanol is a polar solvent and water is totally dissolved in methanol; whereas gasoline is a non-polar solvent into which water cannot easily dissolve.

I don't think I have water in methanol, I tested it's purity and it is over 99% pure. That leaves me with conclusion of bad oil.
