    Push your truck, just kidding. My Escalade gets better fuel mileage than both of my Grand Cherokee's do, and they are 2000 lbs lighter with a much smaller engine.

    Re: fuel economy

    It's really difficult to increase the MPG. You may want to concentrate on not letting it get worse. Your 'Lade came with synthetic gear oils, don't let anyone put conventional oil in the rear end or transaxle. You should use a high quality synthetic tranny fluid and engine oil. Mobil 1 is good, but probably should be changed like traditional oil as its additive wear out. Some of the high end synthetics can probably handle extended miles and maintain good MPG.

    Maintain reasonable tire pressure and choose tires with good rolling resistance values.

    Make sure the brakes are working as they should be. Sticking/dragging brakes can eat up a lot of gas. If you have the ability to switch off the 4WD, run in 2WD.

    And of course, drive like there is an egg under the gas pedal.

    Low restriction muffler/exhaust, K&N airfilter, Iridium plugs? Take out any unnecessary weight from the back like crap that's been there for awhile. Don't jackrabbit start. Drive like Granny on Sunday.

    I did pick up a couple mpg's with the K@N and a turbomuffler on my big-assed Grand Marquis. Problem is that I found myself enjoying hearing the exhaust so I drove more aggressively and lost the mpg. :rolleyes2

    I have (2) Grand Cherokee Overland's, they have the 4.7 HO engine, one is worked and one is stock, the stock one gets 10.6 around town, the worked one get 11.2 around town, they both get about 19 on the highway. My Escalade gets 12.0 - 12.2 around town and 19.6 on the highway.

    Re: fuel economy

    My 2002 6.0 gets 11mpg around town and maybe 17 on the freeway; this is with a magnaflow muffler(dual 2 1/2 in, dual 3inch out connecting to orig. Y pipe It feels like I lost a bit of low end power, but seems much faster on the freeway). I gained about 1mpg from it. I also have 22's and punch it on the start off.
