Anyone flying with E85?
 

I was wondering if anyone had tried E-85 on a gasser yet.
http://en.wikipedia.org/wiki/E85

It's 105 octane and only $1.99 a gallon

As it's 85% ethanol 15% gas can you use in a glow conversion with just a normal 40:1 oil mix?

Hi sscherin ,
The ethanol won't keep the glow plug going. Might work with fulltime battery. To run 85% ethanol with ignition or glow, you may need to modify your carb for more volume. You will need a bigger tank too. You may get more power. I thought about it and decide that it didn't offer any advantage. In San Antonio it cost about the same as gasoline.

The key word is methanol not ethanol

E-85 will work fine with a spark plug, though you will need to richen the carb up. Most carbs can richen enough with the needles, and/or a small adjustment to the regulator for a little more pressure/flow. It will not work with a glow plug however. The catalytic reaction with the glow plug requires methanol. E-85 is ethanol, not methanol. It doesn't even work well with full time glow heat. (Go ahead, ask me how I know....)

The reason ethanol will work with most gasoline carbs, is that it takes less ethanol to run an engine than methanol. When running straight methanol, you often need to modify the carb, or buy one that flows enough fuel stock.
