If the guy ahead of you pumped E85, there might be a pint of it left in the hose when you start pumping the E10 but just to think about a worst case situation lets say there was 1 quart left in the pump and hose.
If you were filling a 2 gallon can that would make 7 quarts of E10 + 1 quart of E85 ending up in the can.
I might be doing this wrong but if I take the 7 times 10% = 0.7
plus 1 times 85% = 1.55 divided by 8 quarts = 0.194 or 19.4% alcohol.
If my guess about there being about 1 pint of E85 left in the hose was right I figure the pint mixed in with 15 pints of E10 would end up with a mix of: [(15 X .1) + (1 X .85)]/16 = .147 or 15% alcohol instead of the 10% you thought you were buying. (There are 16 pints in 2 gallons).
If this bothers you, maybe you can find a pump that does not offer the E85?
To the best of my knowledge, no one even sells the stuff here in Arizona.
I'll start keeping my eyes open to see if anyone is selling the stuff out of the same pump.
Ya know, I think both of us (at least I hope you do) realize that this is just a driveway discussion full of sound and fury signifying nothing
I'm not really an ethanol lunatic running around waving my arms in the air screaming "This ethanol crap is ruining my poor, little motorcycle engine and I'm mad as hell and I'm not going to take it any more".
I know that's not true. It's probably doing no more damage than Dry Gas although I don't know the exact differences in the chemical makeup. I do know that it damages other stuff that it contacts far more than anything it does in the combustion chamber. Alcohol burns quite well there. I'm way more angry at what these lunatics did to the world corn market, but, of course, the media never covers THAT. Oh, no.
My whole bitchin' and moanin' about ethanol is generated by my fear and loathing of this government that I have watched in detail since the '50s pull more and more power over the American people into itself and many many millions don't even realize it, aren't paying any attention, have been lied to since kindergarten OR are getting exactly what they want from this government so of course they just want to maintain the status quo or ensure that the quo keeps sending them a check or gives them tenure or reelects them.
This ethanol scam is just one more thing added to a list of thousands that the government has shoved onto us under the guise of "We're here to help you and we're doing this for you to save the world so just don't look behind the curtain; we'll take care of you. Just go to the mall or whatever your "drug of choice" is and trust us".
The ultimate goal is to leave NO choices to the people and have them not even realize that it happened (and it's been VERY successful). The goal is for every choice to be predetermined and mandated and sealed by law by a central government and those who don't see that will have it sooner or later come clear and it won't matter any more.
And actually ethanol is probably 1/2 way down in the long, long list. What or who is the lesser of two (or 3 or a hundred) evils is now a totally unanswerable question. We no longer have a government that functions for the good of the country. That is long gone - never to return.
