i have been mixing different ratios of reg and 100 LL gas in my RV for years. finally decided to test some samples. i took a extra fuel sampler and marker the half way point with a black line. it measured 2 3/4 inches to the black line. i filled it to the black line with H2O, then topped off with regular sunoco gas. shook it up then let it settle for a minute. it raised up 5/16 inch. questions? does this sound like a propper way to do this? what formula would you used to figure % ethanol in the fuel?
