As a rough guide it'll end up costing about half what you'd pay in the LHS. Mixing is dead easy...just work out what proportions you want, pour them all in together and give it a good shake. It's even easier and cheaper for me because I don't bother with nitro.

Status: offline 		Guess my answer won't do you any good but the costs for me is very minumal. I work for a race team that uses nitro and alcohol, to the only cost to me is buying Klots oils. I use their Super Lubriplate for any fuel less than 20% and the all synthetic for anything I mix over 20%. Never had any engine problems and some of my motors are WELL used and have lots of flights on them. I down loaded a Excel spreadsheet from somewhere that you can plug in the percentages of oil and nitro you want and total amount of fuel you are mixing and it will figure what amount of each to add. Good luck

Status: offline 		Hello!
Done it for 27 years!
Its sooo easy ! Just get a 1 liter jar and mix in methanol, nitro and oil to what ever % you want!
Here in Europe nearly everyone has converted to syntetic oils.
Most use 10-15% oil!!
Nobody uses castor oil anymore!! ( I use it in pylonracing but only because the rules says so)
The oil mostly used here in Europe is sold by Graupner and is called "Aerosynt 2 " and "Aerosave".
The French Motul racing brand is also making there own glowfuel called "Micro"....which I use. I garantie that you will be stunned of how well these oils work ...no more carbon buid up and better trottlerespons and....longer engine life!!
Motul oil could be found in bike shops all around the world!
Try it ...

Regards!

Thanks

Status: offline 		Hallo!
The only ingredients we use in glowfuel is Methanol,oil (syntetic or castor) and nitro( nitro is not really necessary, but 5%-15% improves power and most importantly ...the idle)
Most sport engine ,both fourstrokes and twostrokes run good on this blend...
5% Nitro
75% Methanol
20% oil (castor or syntetic)
This is what I have used for 25% years in all my sport engines


In international pylonracing where we run 6,5cc (.40) engines at speeds up to 200 mph. We use
80% Methanol
20% castor oil.
This is an old blend that is used only in international pylonracing,
not that is good......better oil than castor oil is available today ,but because the rules says soo......!

In Europe today many flyers uses a blend like this....
15% syntetic oil ( Motul "Micro"
5-10% Nitro
75-80% Methanol

Status: offline 		To High Sierra............nitro is sold in auto speed shops mostly for use in dragsters. That's where I get mine. They stock it in 55 gallon drums...bring your own jugs...but I get mine in sealed 5 gallon cans made by VP Fuels. I pay $26 in 5 gallon lots. Alky costs me $ 3 gallon and I use Klotz Heli Glow oil. I get 4 gallon cases of that oil for $100, mix a 24% oil, 30% nitro mix and use it in my YS 140-L and in my heli too.....works too good. They stock cases of KL-200 all synth oil for $48 a case....KL-100 too.
Optionally, you can add 1 oz Propolyene Oxide per gallon of mixed fuel for improved starting & idle. This stuff is commonly called 'igniters' in store bought fuel...but it's expensive so I'll bet most mfgrs don't use it anymore. I pay $8 a pint.
The shop I use stocks Klotz for the motorcycle & model guys, in addition, they will order the Heli Glow if asked.

Status: offline 		Done it all my modelling life. Never bought pre mix (well, a jug of powermaster once in 1997, I was not overly impressed)

If you haven't give it a go. I store methanol and ether in my basement. I'm still alive. Heck, you've got gas in you car's tank ...

At least my containers are steel and rated for the use I put them to ... and sealed.

Methanol costs me $1.50 Australian a gallon. I fill a 20 litre container at a time. Nitro, well, $100 Australian a gallon (4.8 litres). That's why we don't use high %'s of it over here as a rule.

I use none or 5% in my 2's, and 10% of it in my 4's.

My 4 mix:

16% Klotz KL-200

4% Racing Castor

10% Nitro

70% Methanol

Best fuel money can buy

Status: offline 		I too am very interested in this subject. I have methanol and castrol, but do yet have any nitro or synthetic. I have not had any luck getting a source for the nitro yet.

My question is the calculation used to determine the percentage.
Lets say you want 2% castrol, 18% synthetic, 10% nitro, and the rest 70% methanol. How do you actually calculate the quantities say for a gallon? The 70% methanol is not a gallon but only 70% of a gallon which means that 10% nitro would be something less than 10% of a gallon, etcetera?

Status: offline 		I've never mixed fuel before but as I understand it you do the calculations by volume. In your case, by a gallon.

Well 1 gallon approximately = 130oz

2% of 130 = 2.6oz (castor oil)

18% of 130 = 23.4oz (synthetic oil)

10% of 130 = 13oz (nitro)

70% of 130 = 91oz (Methanol)


Add 2.6 + 23.4 + 13 + 91 = 130oz = 1Gallon

At least this is how I understand it. If I'm wrong someone correct me please.

Mike
