    gas guzzler

    I knew the truck was goin to be a gas guzzler when I lifted it, but this is ridiculous. I drove maybe 13 miles across todwn and back and burned almost a half of a tank of gas. Does anyone have this problem also or is there somethin wrong with my vx?? How can I get better gas mileage out of it? Help me plz any advice would be nice.
    thx,

    Mileage for a series of vehicle can vary due to any number of factors such as, but not limited to: tire size, condition, compound and pressure; weight or additional cargo; condition of engine and driveline; additional exterior drag items.

    But 2.2 miles-per-gallon is pretty bad for a VX. I'd say anything consistently under 15 MPG (for a stock VX) would warrant some investigation.

    Mine is lifted and I get 15-20 mpg depending on Hwy/city. I think if I was you I'd be looking for a big leak somewhere!

    it is really ridiculous, It does excellent when I am on the highway but when I am drivin around town it sux gas like no tommorow. I only put a 3.5 in calmini lift on it. I could understand mabee ya know if I lifted it about ten inches if itr got that gas mileage but no just 3.5 and raised the torsion bar about another .5 or so. I guess i will try to clean the fuel injectors tonight but if there is anything else anyone can think of let me know plz.

    Did it get that kind of mileage before the lift doing city driving?

    Did you put significantly larger tires with the lift? If so, that could affect your in-town mileage since you would have effectively changed the gearing to favor highway cruise speeds. When I put 31X10.50's on my '88 Trooper it hurt the in-town mileage, but just a little.

    There's quite a few "big meat" tire folk here, so hopefully they'll chime in with actual VX experience.

    With 31s on my Vx I still get no less than 15 MPG in town!

    Yeah, 31's wouldn't make much difference as the stock tire diameter I think is about 30", but if he has like 33" Swampers or something with a lot of rolling resistance as well as significant diameter. It's amazing how some things increase load almost exponentially after a certain threshold.

    Well at 2.2 MPG you should probably take it in. Something I have always done to vehicles with over 30K miles is do that Seafoam Treatment. It has always cleaned up my engines well and made my Vehicross get maybe a extra 2 miles to the gallon.

    Time to hull the sea anchor (nautical term for bringing in the parachute-like-device the prevents movement in a stiff wind). Sheesh! If I was getting milage like that I'd have that baby lowered to about 1/2 off the asphalt.

    I am running 33's and see 10mpg city and 13 mpg highway

    Something is seriously wrong if you aren't exagerating, or your fuel guage is off

    Is that 1/2 tank because the gas gauge said it was?...or 1/2 tank because you filled gas, drove across town & back, then refilled @ 11 gal. +or-.
    I'm a little suspicious of your gas gauge.
    Just a thought...
