Yabby makes fuel

I have read a lot on this and other forums about Glow fuel;old fuel, new fuel, synthetic, castor, castor/synthetic, castor. I buy my fuel from a large hobby store in Oz and it is 15 synth, 5 castor, plus various nitro levels. As I wasnt using it super quickly I would by it 1 litre at a time. Or as most of you would say 1 quarrrrrt I always added castor to it as I was never happy at the low level of castor for such small engines, that rev so high, and have no rings, so its not a big difference between tight and worn out, so to speak. Compared to a big engine.

When I was young racing TZ GP bikes and after that speedway I was sponsored for my fuel by a local race fuel supplier who still exists today and supplies all the fuel here to the drag racing, speedway, circuit racing, boat racing, you name it, if it has an engine and it gets raced they supply the majority of the fuel and of course to the general public. The fuel is always good as it is getting used at a good rate that way and the methanol is the highest grade racing methanol they can get, same with the Nitro.

Often when I ran my glow engines (All Cox as thats just what I enjoy building, running, flying ), the oil that came out of the engine whilst running the hobby shop fuel (with castor added) didnt look right to me, and when I pulled the engine apart, the internals didnt have that nice bright look I would like to see. Its not a thing based on anything other than many years with very high performance two stroke race engines and a feel for things.

I decided to bite the bullet and mix my own fuel with content I trusted to be very high quality and also to the mix I liked and could alter to suit myself. I went off to the supplier that used to sponsor me and bough five litres of methanol in a new fuel can, 5 litres of race Castor Oil, and two litres of Nitro which was decanted into two black plastic 1 litre bottles. I also bought a 1 litre Pyrex graduated (engraved) jug to help with mixing, measuring and pouring between containers. 250 mils of Castor, 250 mils of Nitro, and 500 mils of methanol, gave me a nice mix I liked. Rightly or wrongly I gave it a really good shake in the container to mix it through and left it for two days before using it. After two days it had gone a nice light yellow sort of colour all through.

I tested it on my Surestart engines and my TD engines, on the bench and then flying them, and they loved it! started very easily, ran consistent revs and the oil coming out of the exhaust was a nice clear yellow! I pulled the engines apart when I got home and they had a really nice bright clear even thin coating of clean oil all over them. Just what I wanted

Maybe its just a Yabby thing, but I think, Make your own fuel if you can, and you can get good methanol, castor, and nitro. Not only did it save me money being about 1/3 the cost of the stuff the hobby shop sells, but im convinced it is better for my engines! If you can get the supplies, it is very easy to make, mix a litre as you need it. Perfect.

I know fuel can be a bit controversial, and many different views and opinions, especially in respect to synth and detergent properties. I didnt use any synth. I like it as just castor, nitro, methanol. Works for me, and Im happy with it. Im sure others will see it differently which is one of the good things about all forms of motor sport and tuning etc.
