gas/glow mix calculator
 
For those who do not have a local hobby shop or a hobby shop that refuses to order the 10/10 glow fuel, I’ve come up with a simple spreadsheet that calculates how much straight methanol and high nitro car or boat fuel to add to your available glow fuel to arrive at the desired mix. This is the way I mix my fuel because my local hobby shop refuses to order 10/10 glow fuel.

The default, when you open the spreadsheet, starts with 10 units of 15% nitro Omega fuel, which contains 17% oil. Then, 7 units of straight methanol is added. Finally, 1 unit of 30/10 car fuel is added to arrive at the desired 10/10 final glow fuel mix. The amount of high test gasoline to add is then calculated.

One could really start tweaking the mixture by adding small amounts of 60% nitro boat fuel to get the appropriate final mix, if you knew the oil percentage of this high nitro fuel. I think it’s usually about 12-14% oil, but I’m not sure. In fact, one quart of this stuff would go a long way in mixing up 10/10 fuel. I tried uploading the Excel file, but it appears that this file type is not supported. If anyone wishes to see this spreadsheet, please respond and maybe we can figure out how to share it.

KI8FR, is East Lansing near you? I found a website for the East Lansing Kart Track. More than likely, they run methanol in their go-karts. Perhaps you could contact them and find out where they get their methanol.

I just used some Morgan Sidewinder car/truck fuel it is 20% nitro and 12% oil, it worked fine on my weedeater and my friends 42cc poulan at a 1 part glow fuel to 2 parts premium gasoline. I think the car/truck fuel is easier to get than the 10/10 large Supertigre stuff.

As of right now I can get car fuel at my LHS. the have 10/10 fuel. but he said that most people like 20/10 in there cars. He does not know how long he will be selling the 10/10 car fuel. East Lansing is about a 1/2 hr from me. I will look them up..

Thanks
