    River Ridge Louisiana-4 miles W of New Orleans-didn't flood-water stopped 800 yards away.


    City driving is a killer.My 1998 5.7 2wd Suburban(210,500 miles) gets 13-14 mpg in city driving-despite driving to get good mp(I drive like a WIMP).On the highway-pure highway or interstate with the CC set at 65mph- it gets an honest 21 mpg.

    City driving kills mpg.
    Our Prius-I know you were kidding about the 15 mpg- gets an honest 40mpg in pure city driving(except my wife gets 32mpg since she literally rides the brake).

    Of course on trips or evacuations(2 dogs, 4 cats, 3 adults live outside New Orleans) obviously we take the ancient Suburban-just no substitute for big when traveling.

    IF YOU ARE DOING MAINLY CITY DRIVING, THEN 13 MPG IS NOT BAD.-if it is 80% city and 20% highway then 13 mpg is about right.If it is mainly highway, you should do a bit better.I would guess you should get 16-17 mpg at 70 mph on the highway.

    PS- Aggressively lugged all terrain tires cost about 1-2 mpg over all weather type tires with street type tread profile.Of course lots of trucks need the aggressive type tires, but I do all street driving,so I don't.

    Yep. It's pretty acurate. I do a combination hiway/city driving, and get about 14.5. I drive pretty conservatively, too.

    My MPG was at 12 for the longest time (i drive pretty quick and have a lot of stop and go's when I'm responding to emergencies in town) ... It was just starting to go up... I got it to go all the way to 12.4 after a few weeks of relaxed driving... and then I got my exhaust system... and that went back down to 12 in a

    She does comapred to me. She yells art me for being too aggresive behind the wheel.
    But she let's down her hair so to speak when she drives my Corvette. She's been known to come back home with a story about racing some honda or something...

    My wife tells me that I'm a "rough" driver, or at least I used to be. But, I like to give it some fuel and I enjoy that take-off feeling. Also, the car has a suspension for a reason! Need to put that puppy into a workout every now and again.

    Dont have the fms or mpg on dic but calculated the old fashion way and we got 18 mpg on our way down to Hatteras mostly highway but heavy holiday weekend traffic and stop and go most of the way down highway 12 thru Nagshead. I guessed we were going to get around fourteen and the wife guessed correctly at 18!
