    A poll to see what your gas milage is.

    I will start:

    Car: 98 Accord 4-door
    Engine: Straight-4
    Gas milage (when it was gasoline): ~25mpg.
    Gas milage (now that we have 10% ethanol) ~21mpg.

    I lost roughly 4-5 miles for every gallon now that we are using 10% ethanol in our gasoline here.

    Don't put guesstimates, I kept the receiptfrom the gas station, it was 13.269 gallons when I had an empty tank with the gas light on. I used the tach to track the milage, it was 280miles. Now the gas light is back on.

    Just round to the nearest value. When in doubt, round down.

    At the moment I drive an Odyssey and the mileage varies between 20-23 depending on how much highway driving is done. I could probably push it up on flat roads, but the area where I live has lots of hills.

    I was driving a Honda Civic 4-DR sedan that got between 35-40 mpg. I miss that car - but it had worn out with more than 180,000 miles IIRC. It needed an engine overhaul and transmission work, so rather than spend about $3K, I took my wife's car and we got her a newer, more modern Odyssey.

    Once that gets paid off, I'd like to find a smaller car, maybe a hybrid, that get 40+ mpg. And I'm trying to use a bike or walk for short trips.

    Your poll numbers need to be much, much wider. Few SUVs get above 18mpg and many mid-size and compact cars get above 30.

    I drive a Mazda 6i (2.4L 4cyl, 160hp), advertised at 26/32, but I get more like 24/29.

    I'm surprised you were only getting 25mpg out of that Accord.

    You can fix the pole range if you want to Russ, if not, Ill fix it. (Man I am lazy.)

    I think Cyrus is right on the reduced performance with the ethanol blends. I have observed the same, and I think Pennsylvania may also be using ethanol blended gasoline.

    I currently drive a BMW F650GS motorcycle which nominally gets 70 mpg. I'm probably not getting quite that much.

    ya when you save all that money on gas your family can buy you a bigger tombstone after you hit that tiny bump on the highway and get flown 100 yards into a volvo driven by a soccer mom

    Ethanol is "precombusted" --- look at it this way, it's 20% burnt ethane when you buy it. Something of a rip --- does drop operating temps and NOx and CO emissions.

    Last time I calculated, Swerve's Expedition got about 11 MPG. Not a poll option.

    Dear god, that's horrible. I honestly thought my poll options were at the upper and lower ends. :surprised

    She's been trying to get a new car for two years now. It looks like her parents are finally going to relent and buy her something before the end of the summer.

    I have a '92 Accord 2-door that dives me about 32 on the highway and about 29 on city roads.

    yep, selected less than 19. The Honda Civic Hybrid I want allegedly gets 50mpg.

    Since you said 'no guestimates', I can only give you figures for the Roadrunner. If I kept it to 59 mph (flat road, no wind), it got 25 mpg. At 60, the secondaries on the carb started to open and it dropped to about 23. If I put my foot in it, or got stuck in city rush-hour traffic, forget it. Probably 5 mpg or so. I once had to pass 9 cars stuck behind a motor home doing 50 mph on a 2-lane highway. Downshift to 2nd and balls to the wall. I was doing 145 mph when I went by the motor home, and immediately dropped back to just above the 60 mph speed limit. That little manoeuvre used about 1/8 of a 22 gallon tank of gas. It's hard to say for sure, because acceleration forced the fuel to the back of the tank and let the float drop. All that I know for sure is that the gauge dropped from 1/2 to 1/4, then slowly returned to 3/8.
    Keep in mind, though, that I'm using Imperial gallons which are significantly bigger than US ones. Also, the thing required a minumum of 95 octane leaded, so the addatives seriously kicked the cost above what it would have been had I been using normal gas. (The motor, by the bye, is a .030-over 440 at 12.5:1 compression--approx. 650hp. Curb weight is about 2800 lbs.)
    The Camino is significantly better, although not nearly as fast. About 27 mpg out of a 455 Olds motor, as long as I stay under about 75 mph. (It's slow, but it'll climb over anything.)
