What are you guys using to measure your e85 content?

You can use a graduated cylinder with fuel in it, add a pre-determined level of water, and the fuel will float (sink?).

So if you took say 100ml of E85 mix, 15ml should be gasoline, 85ml should be ethanol. Adding 100ml of water should separate the ethanol+water from gasoline, and leave a clear 15ml level of gasoline, and 185ml of water/ethanol blend.

My bad let me re word. What sensor is everyone using to measure their ethanol to octane mix?

I use this and its fairly large and easy to handle:

I just do the math and run a full take of 91 in between mixtures. Not efficient at all, but I don't think we have a sensor of any sort to measure currently...do we?

Fuel-it have one for the B58?

JK there is one. Probably should get on that. lol
