That is possible. The stickers in the gas station say "up to 10%" ethanol. We could be getting 10% or 5% or 1%. Perhaps we get more ethanol in the mix in winter months and the content drops in summer. I tried to look for this info but it's not easily found. No one at the station can even point me in the direction of where to go to find out. I think the best way to know is to take a sample and test it and do it on periodic basis to find out what's really in it. Another thing to think about, as corn prices rise and ethanol becomes more expensive to produce, I imagine gas producers may cut the blend down to keep the prices from rising too much. I am sure they're under pressure to keep it as low as possible. May have an effect on how much is added to the mix.
