Wow, guys! Thats a lot of statistical gymnastics! I find it sufficient to just say;

A) Cars get slightly less mpg on ethanol blended fuels than on non-ethanol blends
B) Actual mpg results vary, depending on a list of variables to numerous to worry about.

Just teasing you, I can appreciate the devotion to accuracy.

dang, a new O2 sensor fixed mine.

pure-gas.org shows that 100% gasoline stations have increased by 100 over 4 months to somewhat under 5000. With the end of ethanol subsidies at the end of last year, there is no rush for gas stations to sell 100% pure gasoline.

At the end of autumn 2011, I switched to 100% pure gasoline. As winter took hold(not a good time for mpg increases in northern states), our 3 cars increased their mpg over 10% ethanol blend by 7-8% for a 1988 Ford Festiva.....

More accurate assessment of my 88 Ford Festiva 4 speed comparing 100% ethanol-free gasoline & 10% ethanol blend, now indicates that Festiva has increased its mpg by 7.8%. & the 7.8% increase was accomplished including winter in the northern U.S., where winter mpg is always lower than the yearly average.

pure-gas.org now indicates that stations selling 100% pure gasoline, have increased to 5070.

Five stations in cali is a start. Too bad id have to drive 11 hours and stare at redwood trees to get it. I think ill stick to the ethanol for now.

I just checked the site and there's a station 15 minutes from me. Never would have thought it.

lack of access to 100% pure gasoline

Yeah, large populations of the U.S. & Canada have little to no continuous access to 100% ethanol-free gasoline. That is why pure-gas.org tries to get the word out to increase stations selling 100% pure gasoline.

Ethanol does decrease nitrous oxides in the atmosphere quite a bit & that is why 100% pure gasoline is restricted in most large cities. But to control one pollutant by using ethanol, other pollutants are raised slightly. The EPA needs to encourage industry to find other methods to control nitrous oxides WITHOUT decreasing mpg by 6-8%.

The ethanol industry & EPA need to quit lying that mpg is only reduced by 2-4%. Even that is no excuse for taking away that amount of mpg(which is actually greater), plus taking away smoothness(specially during shifting), quietness & extra power.

Yes, that's why pure-gas.org exists..... to get the word out on 100% pure gasoline & to encourage its availability. Please test the quality of the station's 100% gasoline, by watching your mpg closely & the quality of ride 100% pure gasoline gives. There are even fuel-testers to check that reported 100% gasoline IS 100% GASOLINE. Also, report your results to pure-gas.org. If the station isn't selling 100% pure gasoline, report that to pure-gas.org. There is even provision for you to remove the station if it ISN'T selling 100% pure gasoline.

Many providers of 100% pure gasoline are enthusiastic about their 100% pure gasoline. So tell them your results from using their 100% pure gasoline. To several providers, I have left printouts(line graphs included) of my 'before & after' results comparing 10% ethanol blends against 100% pure gasoline.

Exemptions to the use of 100% pure gasoline

Five stations in cali is a start. Too bad id have to drive 11 hours and stare at redwood trees to get it. I think ill stick to the ethanol for now.

Marinas, airports & farm co-ops may have 100% pure gasoline, often at higher cost. They are exempt from the use of 10% ethanol blends. They may have restrictions on public use of their 100% pure gasoline, but maybe not. Look hard for such in your areas of travel.

I would pay 25-30 cents per gallon more for 100% pure gasoline at the prevailing $4 per gallon of fuel. Fortunately, there is a station selling 100% pure gasoline near my normal travel route selling for 2-7 cents above the cheap Arco 10% ethanol blend.

NO ONE IS "LYING" TO YOU!

Ethanol is 66% as efficient when compared to gasoline (energy per volume), so you might look at this and say “Holy crap, I will get only 66% the gas mileage!”, but you would be very wrong.
When fuel contains 10% Ethanol and 90% gasoline, you are actually only losing 3.4% mpg!
This can be easily proven  (0.1)(0.66)+(0.9)(1.00) = .966 = 96.6% efficiency

Of course, the ethanol industry & EPA lie, when they only mention the btu losses per gallon when substituting 10% ethanol in 100% ethanol-free gasoline. Of course, your equations only deal with btu loss, also.

The ethanol industry, EPA & you do not mention that an engine specifically designed to burn 100% pure gasoline, will run less efficiently when burning 10% ethanol, on top of the btu loss.

Thousands of drivers prove it. Losses due to 10% ethanol use are greater than 2-4% that the ethanol industry, EPA & you mention. After switching to 100% ethanol-free gasoline, our 3 cars' mpg increases are 6%, 7-8%, & 8%.

Litesong making friends again!

You bring up an interesting question, even if you didn't intend to, do you really know that the engines produced today are designed to run best on 100% gas or 10% Ethanol? Or as more likely the case to use a range of compositions between 10% ETOH and 100% gas?
Clearly 20 yrs ago, the festiva wasn't designed from the start to use 10% ETOH regularly (it was designed to tolerate 10% ETOH in its fuel system) where as more modern engines have had to content with it as the main fuel it will likely see.

I also find it odd that you keep pushing your MPG numbers, but unlike Darlo, myself, and others on here who have "published" our MPG logs via Fuelly or other sites, you don't show us your data!

^Might I also point out to my fellow Washingtonian Litesong that the gas we get here in WA is pretty crappy despite the refinery in Anacortes. Arco gas is also crappy and killed one of our cars, and recently I believe there was one where the Diesel and Regular tanks got mixed up... And our weather is highly variable around here, I get about 3mpg better just when the weather stays above 50 because I have a short drive to school where it doesn't warm up much

I might do it, but it's 15 minutes out of my way to get it. So an extra 30 minutes and about 14-16 miles of extra driving just to get the gas. Probably won't happen.

I would be willing to bet, that if he posted his data (un-doctored like yours and mine), that his average would be much less than ours. For his cause (misguided as it is), he is better off choosing those few fill-ups that best suit his purpose.

I have nothing to hide, and make no unsupported claims!
