Rambler45 -> Home brew dye (5/1/2007 4:56:47 AM)
I started mixing my own fuel to save on $ Have been given a drum of methanol and got me some castor oil. Been mixing to 20% oil in the fuel The question is, I want to make the fuel show up in the tank, like premix fuel Can I use food dye ? Thanks

I think food dye has water in it, though I doubt it has enough to make a differance.

Rambler45 -> RE: Home brew dye (5/2/2007 12:40:38 AM)
Oh did not thought of that. They must be using some kind of dye to make those colours

brewski -> RE: Home brew dye (5/2/2007 12:57:15 AM)
Some speed shops have synthetic that is different colors. A local shop that I am buying from offered oil for methanol in various colors. I just don't know if his oil is okay for rc engines. Do you guys have a good source for synthetic oil?

XJet -> RE: Home brew dye (5/2/2007 5:00:40 AM)
I've used food coloring for years, it has no perceptable effect on engine performance.

Rambler45 -> RE: Home brew dye (5/2/2007 6:28:25 AM)
brewski Yes have access to synthetic oil, are they normally coloured ? I was using straight 80-20 methanol-castor, and have not bought any synthetic before xjet Can you tell me how much do you normally use ? Like just dump the stuff in until the colour looks about right ? Do the stuff like colour the side of the plane or car permanent ?

XJet -> RE: Home brew dye (5/2/2007 10:44:49 AM)
It usually only takes a few drops (4-10) per gallon, especially if you're using that dark read immitation cochineal color -- it's wicked strong! One thing to watch though is that most of the food dyes will get bleached by sunlight so if you leave your fuel-jug in the sun, the color will fade. But then again, the same thing happens with most commercial fuels anyway. I've never noticed any staining when using food coloring in my fuel.

Jezmo -> RE: Home brew dye (5/2/2007 6:57:28 PM)
After using red food coloring in my home brew for a couple of months I took my engine apart to see how it was wearing with the home made fuel. The inside of the engine had just a slight red tint to it. I have also noticed that after using CoolPower green fuel the inside of the case was slightly green. I have never noticed any staining outside of the engine. [8D]

Rambler45 -> RE: Home brew dye (5/3/2007 9:05:59 AM)
Thanks Xjet Went to supermarket and got a bottle, and had a go at it and boy it sure looks like the pre mix stuff. I put one drop into 1 litre and it still comes out when I mix up to 4 litres. Jexmo Thans for the info, tinting inside the engine does not bother me, all I am concern about is stains on the side of plane and truck. Oh I spill some on the concrete and it did not stain that, I suppose that as a food dye, it should not stain anything, maybe the insides stomach. :-) Thanks you for help

Fuelman -> RE: Home brew dye (5/17/2007 3:00:11 PM)
food dye will work just fine, they are either alcohol, glycol or water based. None of them will offer up any problems used in the quantities needed to tint fuel.

biggy_boie -> RE: Home brew dye (5/22/2007 3:15:27 AM)
where do you get the methonal and do y ou need to a nirto it may sound dump but i have no clue on how to do this and it sounds like i could save some cash like this

jetpack -> RE: Home brew dye (5/22/2007 6:28:56 PM)
biggy, Just look for threads here in the fuel forum under home brew or methanol, nitro, oil...thats what this whole topic section at RCU is about [sm=teeth_smile.gif][sm=thumbup.gif] Methanol in small quantities can be bought as HEET gas line dryer...but look for motorcycle or race kart shops. Alky and oils can be found there, but you'll probably have to order Nitro from someone.

Sport_Pilot -> RE: Home brew dye (5/22/2007 8:18:35 PM)
Do a yellow page serch for VP racing fuel. If no distributer in your area then search for their website.

biggy_boie -> RE: Home brew dye (5/22/2007 9:45:41 PM)
thank you very much for the great help

jetpack -> RE: Home brew dye (5/22/2007 10:22:22 PM)
About your question concerning adding nitro...here's the deal on that...the answer is no, you dont have to...but a small amount helps with idle and throttle transitions. You can save money by simply using 80% methanol and 20% oil (usually castor oil, or a mix of synthetic and castor to keep things cleaner) and use less head clearance by removing the shim that's under it. There's fine points to all this that I have said though, so study up a little and you'll see its not that hard to do.

Rambler45 -> RE: Home brew dye (6/2/2007 10:37:25 AM)
biggy_boie When I was in Canada, I usually just buy the RC fuel at LHS, less hassle that way But down here in New Zealand, rc fuel is not exactly cheap, hence worth the hassle. Methanol is pretty cheap here, apparently we have a plant churning out these stuff in Taranaki. But they not easy to get because of shipping due to dangerous goods transport. I been getting them from a friend who is running methanol racing cars. Nitro methane is another problem, so I just avoid it all together If I am you, I would just buy them at LHS.

XJet -> RE: Home brew dye (6/3/2007 9:06:33 AM)
Durian, how much are you paying for your methanol? Our best price in recent months has been around $1.98 per litre. As for nitro, you can buy it cheap/easily from USA Specialty Products in New Plymouth. They charge $85 for four litres of Nitro including courier delivery and (from memory) about $25 for 1 litre. I believe they also stock Klotz oil (Super Techniplate is $59 for 4ltrs including courier delivery). Give Gary a ring there, tell him Bruce Simpson sent you :-)

Rambler45 -> RE: Home brew dye (6/4/2007 10:53:32 AM)
Actually Bruce, I have been given a 20 litre of it and I just used up the last of it to mix up my last batch. But have priced out at about $60 for 20 litre, not sure of the quality of it though. It is the oil that am having problems with actually, getting them at $20 for a litre is kind of steep, especially when the methanol is free :-) Am trying not to use nitro if I can to save $ Have been experimenting without it for a while now. And thanks for the pointer to supply.
