Thanks, this told me on a new link:
Ethanol Labeling Laws - State by State Guide.
Something I didn't know. OH does not require Ethanol labels, and my "assumption" of Ethanol free gas by not be correct in my town. What I do know is that Kroger gas that has no labels gets me more MPG than CostCo gas with labels. It just may be the amount added, I don't know but will research further.
Edit: Testing Alcohol content of gas.
Buy a plastic 100ml graduated tube: http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
And follow this test procedure:
Add 10ml water, 90ml of the gas, cover or stopper and shake well. Let set 15-20 mins. Look for the separation line of water and gas. The water takes the alcohol with it out of the gas. A water soluble dye (food colorants will work) can be used to easily distinguish the phase between the water and gas layers. Add dye to the water before putting the dyed 10ml of water in the tube.
You use 90 ml to calculate total percentage.The test is calculating the percent ethanol in gas, not in the mixture. The purpose of the water is to extract the ethanol from the 90 ml of gas.
If the line is at say 25ml, you know that 25-10ml = 15ml Alcohol
15/90 = 16.6%
