MPGs still bad

[buckshotz43]

i posted a thread back when i first got on this site last year. in all city driving im avg about 12-12.5 mpgs thats if i go pedal to the floor or not. no matter how i drive it seems to stay there with 4wd i get 9-10. not sure why it is i have 4.10s in the back and 235s on it as it says on my sticker. had a tune up done on it reg oil changes, changed out all the filters out. ive also noticed that my speedo is about 1.5 to 2.5 mph off. The engine runs great no problems whatsoever and tranny shifts clean. anyone have any ideas what could possibly be causing it?

If your speedo is off, then your odometer is likely off too. You could be getting more miles/tank than your odometer is showing, which would result in bad data.

That's what i was thinking too, however when i drive interstate i get about 22 mpg then i figure its nothing more than how the roads are in my town lots of up and downs and stopping but at the same time i have a friend with a 3.0 he gets 15ish but less on the highway

22 highway mpg is a pretty decent number for a 3.0 4X4 extended cab. I'd guess that the stop and go driving, and the hilly terrain are what's bringing the mileage down so low in the city.

I guess so, I only wish for once its something that needed fixed lol

i guess some are good on gas and some arent. you bought a ranger not a prius, it wasnt made to get wonderful gas mileage
