Thanks for all the people who sent me a reply to my questions.

However I'm buying pre-mix at $6.40 a litre. I worked out with some prices that I will be saving around $3 every 5 litres which is not much.

Upper cylinder lubricant is usually added as a small bottle to a full tank of petrol so the amount involved would be far less than 1% and whatever they're using obviously mixes with methanol so I can't imagine it causing any harm. At the very worst there's the tiniest chance it won't be compatible with whatever oil you use.

Status: offline 		Cool power gold is 30% castor 70% syn just like omega . Small RC engines use heavy green coolpower and will be replaced with green MV That is because of high rpm ,heat,no or little oil control on pistons. I,m not sure if gold is made in heavy so use med. to be safe.

Tell me if you know what the fuel ratios where back in the day when Cox was making fuel for both there Regular engines
and their Glow engines.
Is there anyone else currently making the fuels with the same mixtures or will I have to make my own blend?
I am thinking somewhere around
29% Castor Oil
5% Nitromethane
66% Methanol

are these close or is there someother combination or other additives that no one else is using to produce todays fuels.

Would like the feedback

Thank You

Status: offline 		What size engine are you looking at running? 29% Castor is an awful lot.

Cox used to have 2 blends for their glow engines. On was sold in a blue can (Standard) and the other in an orange can (Racing)
The "racing" blend had about 25 % Nitro and their engines really screamed on it. I cannot remember what Nitro content the Stadard" mix had. 10 % rings a bell though.

That's the old Dukes Fuel used by the Fox .35 Stunt. The extra oil helps keep that engine cool and improves its 4-2-4 break from four cycle to two cycle and back. Cox probably needs 20% to 22% all castor 15% nitro and the rest methanol. I think the Cox racing fuel was 25% nitro instead of 15%. Also had a small amout of acetone added as I recall. The racing fuel would eventually eat up the styro wings on the foam winged models.

Status: offline 		hello all
I have become interested in the idea of mixing my own fuel after i spent a weekend were i a whole gallon of fuel... at $22sgd(14US)/gallon and 4 gallons/month=88bucks i cant afford that on my allowance.
so i want to make my own fuel.

But here in Singapore for just mentioning the word chemical you'll probably get arrested and fined and jailed and gassed etc(not really, but you cant get chemicals)eg. nitromethane or oils of soughts.

but what i can get is methanol and 2stroke oil.... so my question is would it be possible to run a 2stroke glow engine on 2stroke motorcycle oil and methanol?

thanks regards
James

Status: offline 		Make sure that the 2 stroke oil is compatable for pure methanol use. For example Klotz makes a full synthetic KL-200, a synthetic/castor blend KL-100 thes are for use with methanol and nitromethane type fuels. They also have a blend designed specifically for gasoline model engines KL-300 which is not recommended for pure methanol/nitro applications.

Also what size engine are you making the fuel for? The larger glow engines like the Moki 1.8 and 2.1 will run great on no nitro but smaller glow may not run as well.
