Fuel Mileage Related Discussions
It's my understanding that it also affects how the car accelerates and how long it stays in a lower gear.
Doing a comparison test for MPG is almost impossible, as you suggest. You need a closed course, strict controls, and precise fuel-measuring equipment. Everything from ambient temperature to wind speed and humidity can affect fuel mileage.
Quantitatively, I have no idea what kind of difference it makes, but I've had my econ button on since leaving the dealership, too. I finally turned it off while driving on city streets just to test it out, and holy smokes, the acceleration feels completely different. It's so much snappier. Makes it pretty tough to switch that econ back on after feeling the powahhh.

I've driven ours since new without the ECO button. I did try it once and it felt like hooking up a loaded trailer to the car. No fun!
I am a little disappointed! The past few days I drove 274 miles and used 7.6 gal. About 34 miles city and 240 hwy, with eco on and about 20 miles using AC. This is about 40.9 MPG and I see some people getting more. Car has about 1120 miles on it. Am I expecting to much. Speed was about 70 mph on highway.

okies So, Today I took my White 2015 Honda Fit LX-CVT from East Bay, CA to Fresno, CA I really wanted to see how much gas I would save on the open road Taking the 5 HWY. I filled up and had my Eco Boost on the whole time. When I got to Fresno area I got about 190+ miles put on her. I got there with Half a Tank of Gas (I put middle Gas (89 I think) of Shell). Then! to test things out, I just came back without Eco Boost and guess what...when I got back I still had Half a tank of gas. So at this point I'm thinking...what is the Eco Boost Saving me? Why do I have it on? is it faulty? and just so you know, the average MPG was 35 MPG both ways.

Do the same trip again sometime and switch it around: leave the Eco Boost off on the way there and turn it on for the trip back. Let us know.
Made my first long trip in my EX Fit. 6 hour trip to the beach. All interstate, 75-85mph, with about 15 minutes of idling behind a wreck. Eco Boost on, AC on low.
36.5mpg on the trip computer, and 34.74 actual.
I'm pretty happy with that. 35-36mpg seems to be the ceiling on my EX when traveling at 75-80mph.

Thanks for the reply. I still can't figure out how to get the fuelly icon? on my posts. Bill#22335
All of these 34-39 mpg are depressing. Yes I know that is in the middle of the EPA mpg range for the car but I had hoped to see more people claiming higher. Sadly fully.com is right there with everyone. I was hoping to read dozens of people eaking out ~45 all over this thread. Shame.
And there's the key. The car won't hand you good mileage on a silver platter, but it will let you eke good mileage out of it.

Winter blend arrived at the beginning of this month for our area . Called local gas supplier for verification . Gas mileage has dropped about 3 m.p.g.. Some blame goes to colder days and strong winds . Here's the gas mileage picture thread for the '11 and '13 base Fits with the auto . http://www.fitownersclub.com/forums/...d.php?t=123001 .
