I'm wondering what is your average MPH?

Actually I went from 15 mpg in the summer to 17 mpg in the winter. Not so bad

Im getting around 13.8 MPG, I truly don't know what cause such horrible mileage as i truly dont ride it hard but I will try Shell and see what the results are. Also how on earth are people getting 22 MPG!!! And its full New England city driving...

Even if they blended 10% water with gas, you wouldn't see more than a 10% drop in mileage. Ethanol does have less energy per volume than gasoline, but since it only comprises a max of 10% of pump fuel, there's no way you see a 10-15% drop in mileage. It's still more like a 70-90% equivalent energy content (not sure and too tired to look it up). So you might see a drop of between 1-3% at the most.

20-30 here, avg 21mpg on 80% hwy at 70-75mph. My car isn't broken in yet, only 4k miles.

Coprolite

My average is about 30 mph and just over 20 mpg, but I have less than 1k miles. This last tank coincides with the recent cold front (below freezing is cold by TX standards). The MPG on this tank have been noticeably lower(~17). Perhaps the summer tires turning to stone or the short trips to work exaggerate the extended time it takes to get up to full operating temperature.

I get a max of 28-30mpg in the summer & 22-25 w/ Ethanol, and somewhere in between in winter on non-Ethanol fuels. It's a very close to 10% decrease in my fuel economy. There may be something other than just the Ethanol going on here, but I've heard from enough other drivers that have experienced similar mpg losses to believe it is indeed Ethanol related.

Coprolite

If ethanol is added in the winter, it is also added in the summer. Ethanol, up to 10% is pretty much everywhere, as MTBE is no longer a kosher additive and ethanol is the only "eco" choice. It is mandated by law in many states. If you know a place that sells real gas in the summer, they will sell it in the winter, too.

I still haven't come across a gas pump that didn't have the "May contain up to 10% ethanol" disclaimer.

I'm averaging ~20.8mpg for the last few tanks. I have snow tires and all of our gas here in the Chicago area has 10% ethanol.

In the summer, I usually get around 22mpg. I do about a 50-50 split of highway and local driving, so I'm pretty happy with this number.

ok, so this is related to a lengthy jaunt on the highway but it's worth noting. I had a stretch of about 160 miles on the freeway yesterday. So I reset the dash and hit the road to see what kind of mileage I would get. No traffic, no stops, 65-80 mph the entire time and here's the outcome.

Average MPH 73.9
Average MPG 30.3

yep, I'm pretty happy with that.

Downhill . . .

^negative....pure flatland freeway cruising. Elevation maybe changed a couple hundred feet at most the entire drive. Real true numbers. Guess I'm lucky...but I'll take it. City driving is a different story, but all in all I average around 22-23mpg and I have a more "spirited" driving style than most.

I'm seeing around 20mpg right now in the X, but it totally varies depending on the week and if I'm doing more local vs. highway.
