no offense taken. ALWAYS question data and results its the sign of a working brain :-) its also the sign of a working open mind not to automatically DISMISS data either without testing.

The data is pretty solid though not PROOF as of yet. this part of the experiment is meant to determine if the next step is worth the expense of time and money IE drive hours away to get some real genuine ethanol free gas

even as it stands though the data is pretty damned conclusive if you look at the numbers.

The metro has NEVER EVER seen mpg's this high since the day I bought it last october.

ZERO mods ZERO significant repairs since I bought it and got it on the road. ZERO changes or repairs to engine exhaust or fuel system

On top of that during the time that I tested this in the metro check the weather for my area. below 55' rain and heavy winds the whole time. about the worst conditions you could ask for for FE testing and it still scored insanely high just by removing the ethanol.
Now that the weather is WARM and STAYING warm I expect even greater results fro the metro.

the jeep is even greater a change. Look at the conditions under which I tested it! worst possible conditions and it STILL scored 23% HIGHER MPG than it has in the last 2 years! ie I am VERY hard pressed to get better than 17-18mpg with the cherokee since going to ethanol with it usually closer to 17mpg

I got 19mpg a few times but that was PURE highway turnpike driving at 55mph.

I am sorry but a 4mpg jump over 20% higher than its 2 year average on ethanol is nothing but conclusive that "something" it going on.

NO amount of driving style short of extreme hypermiling and aeromodding is going to raise a 493,000 mile 88 cherokee's FE 4mpg.

the metro has gone from getting 10mpg lower than its factory rating to getting NEARLY EXACTLY what the factory rating says it should be getting. Again pretty damned conclusive.

I had to drive 42-44mph with EOC etc.. etc.. just to wring 49-50mpg out of it.

I put 7 gallons of Eth free gas in the metro and do ZERO EOC and its cold and raining and suddenly I am getting 54-55mpg? 7mpg HIGHER than my best pre winter mpg of 48mpg.

and ZERO hypermiling!

ALSO look at my "dates" I get gas every 3-5 days usually. almost twice a week at times. So changing weather patterns on a seasonal scale do NOT effect my tank to tank data. Just look at my fuel log.

There is not much of a log for the jeep because I stopped driving it (got too expensive to drive) and usually never drove it long enough to record a "tank"

but the metro I have EVERY SINGLE drop of gas I put in that car except the very first tank on my log. The data speaks loud and clear.

"SOMETHING" is going on here :-)

Current data says its the ethanol. When I make the trip to get 40+ gallons of E0 that will confirm the data. I plan to put a few thousand miles on the car in a couple weeks. this will eliminate weather as a major factor. I plan to go a few tanks on E0 then a few on E10 then a few on E0 then a few on E10. THAT graph should prove very interesting.

I wish I had the money and will power to make up 30 gallons for my Club Wagon. man would that be interesting. It was hit the hardest going from a solid 4 year average of 19mpg to 13-14mpg on E10 15mpg if I baby it on Wawa E10
