    04' escalade has horrible gas mileage??...

    hey guys.....i just bought an 04 in may...so far the gas mileage is horrendous...my 02 was way better than this...when im about half way down on the throttle i get a whistling noise form the motor, could there be some kinda vacuum leak causing the mileage to be this bad?..i dont get it....i filled up passed the full mark..and 45 miles later is was down to only 3/4 of a tank...the guage on my 02 wouldnt have budged with that mileage...are the tanks the same size?...any info would be great...thanx

    What are you getting mileage wise? City, Highway? I get 12.5 - 13.0 around town, and usually over 20 if I keep it under 70.

    I live in Staten Island, NYC and I get 9.5 MPG so, I must fill up atleast once a week at $35 to get a full tank from a little under the quater mark. That is nuts.

    I had the computer reprogrammed by a local guy and have a Volant air intake and Corsa exhaust.

    I've stuck right around 12 since I put my rims on, was getting about 13 before. On highway trips I think I usually get around 19. If you're only getting 9 mpg there's a problem, even after resetting the monitor and driving real hard I've averaged over 11.

    I do mostly fast and furious city driving and I still average just above 14 mpg on my 03. On very long trip we always take the wife's honda...it gets 30 mpg.

    if the gas tank holds 26 gallons, i used about 5-6 gallons for 40 miles....there is def something wrong...that would put me at 160-170 miles for a full tank...the computer says i have 240+ with 3/4 of a tank left...time to go to the dealer....

    I just got my car back from the dealer, they are still trying to fix my window squeak...actually they gave up and just ordered all new parts for the drivers side. i have an intake and a corsa exhaust too and i dont drive that hard at all what could this problem be?

    If you have a 6.0 AWD it calls for 91 octane, it will run on less, but it retards the timing so you would get worse fuel mileage

    Mine inhales gas but i got a lead foot. The only thing that eats gas faster is the Cobra with the boost on. I drive 100miles a day and it is costing me around 20 dollars a day in gas. I think i am going to drive the beater a few days out of the week to slow the gas bill.

    The average on the display shows about 13 so that's about right.
