On a recent trip from Knoxville TN to a suburb of Indianapolis Indiana I started out my trip with a fill up from my local Kroger that uses "10% ethanol blend". Used the cruise control set on 80 mph for the majority of the trip and drove straight through.

Dash computer said 21.9 and calculated based on miles driven/fuel fill up was 22.5. I ended up filling with ethanol free gas at a station I found in Indiana and put about 50 miles of local driving on it. Computer was showing an average 22.1 mpg with around town driving on pure gas! Much better than I usually get.

The ride home was even better. Again, I set the cruise control on 80 and drove straight through. When I got home the computer was showing 25.9 mpg and I had 91 miles left. Not bad. Calculating based on miles driven and gas filled gave me a whopping 27.2 mpg!

"Fill up" for me is filing until the pump shuts off, removing the nozzle to "burp" my tank, putting the nozzle back in and pumping until it shuts off again.

Too bad its getting more and more difficult to find stations that sell pure gas....

In some areas (like Houston and surrounding counties) all gas has 10% ethanol all the time.

 

there is NO place in connecticut without at least 10% ethanol.


wish they did

 

Pretty much expect 10% worse mpg w/ 10% ethanol, that's been my experience, damn crap is just a wasteful filler

 

and a way of getting older cars off the road....

We get a handful of ethanol free gas stations here in WI. I only use 91 Shell V-power, but it's almost $.50 more than 93 10% eth any where else. Wondering if it's worth it or not...

 

I haven't found any ethanol free gas here in DFW but I drive to Oklahoma City a lot and they have it there. I always get better mileage with it.

 

ethanol has 76,100 BTU's of energy per gallon whereas gasoline contains 114,000 BTU of energy per gallon. So you need to burn more ethanol to achieve the same level of power as you would with gasoline which decreases your mpg. Also blending ethanol with regular gas makes it burn slightly slower therefore increasing the octane rating. Typically 93 octane has up to 10% ethanol. Also ethanol gums up fuel lines and is just not good for engines. You actually pollute more with ethanol because you need more of it to burn. But its renewable right?

 

theres alot of ethanol free gas in NOLA. fill up everytime. never went back to shell or chevron ever again

 

If you're looking for a station where you can get E0 gas in you area, try Ethanol-free gas stations in the U.S. and Canada

Found several stations in my area using that site. Easily worth it to go a grade lower if you that's what you have to do to get E-free gas. My 2ȼ

 

They best place to find ethanol free gas is a gas station near water where there are a lot of boats because boat engines can not handle ethanol so they sell ethanol free gas there.

 

I'm in landlocked Atlanta, and I cannot find ethanol free gas here. I wish there was at least one place though.

 

So after a couple weeks of driving on ethanol free gas and then switching back to the 105 EDIT: 10% crap at my local Kroger, I can certainly see a noticeable difference between the two.

Up front, my local Weigels that sells ethanol free charges close to 0.50 more per gallon than the premium with ethanol. It costs more to fill the tank but the mileage and range are better. Doing the math though, it costs about the same for the two.

You got 105 octane race fuel at your local Kroger?? Here in Dallas, TX I have never seen a ethanol free gas station.

 

man 105 being crap? my 93 octane must be like water..
