I just read something on how to test pure gas quickly without using water etc.
Food coloring drop.  If E-free it don’t start to dissolve. Stays solid beads after stirring.
If it has ethanol in it it starts to dissolve after stirring etc.
I just tried it with e-free and ethanol gas.  If true it does as I read.  😳😎

Pics for proof.

It is simple to test for ethanol. Here is how the pilots can do it:

Recently a member of the Aviation Fuel Club, Gilbert Pierce of Germantown, Tenn., sent us the description of how he tests for ethanol using a few drops of ordinary food coloring:

“While driving 20 miles into Mississippi to get ethanol-free gasoline for my airplane I was contemplating what must be in the blue dye that is in the Quick Check Solution kit. It occurred to me that what ever it was had to be water soluble so it would mix with the ethanol. I always check the suppliers of ethanol-free fuel before pumping any gas as I have been lied to about it. Anyway, the test kit that you add water to is a hassle and takes a few minutes to settle out. The blue Fuel-Check works great but is expensive. When I got home I got my wife’s red, blue and green food coloring out; it’s water soluble. A quick check with pint jars of ethanol-free fuel and adulterated fuel indicated that a drop of any color food coloring will dissolve and turn the adulterated fuel the same color as the food coloring. Putting a drop of food coloring in pure gasoline, the drop just goes to the bottom of the sample and rolls around there as little globules. Now I just carry a bottle of inexpensive and readily obtainable food coloring and a quart glass jar – it’s easier to get a fuel sample into – and have an instant indication of ethanol free fuel or adulterated fuel.”

Remember, always test every batch of gasoline purchased at any location other than an airport — “Let the buyer beware” !

We are going to get our methanol blended fuel M15.
What is the difference compared to E fuels and are the adverse effects the same?

I know I raced using methanol nitro and had to flush saws after use.  Dont know if because of the methanol or not.
