Some of us have swapped out the differential and tranny fluids for fully synthetic oils and that has shown to improve the MPG quite a bit. A CAI wont hurt, but if you use the stop sign as a launch pad every single time, like ntrddragn does, then it wont help at all. :D

Some have found marginal success using a Bully Dog/Super Chips Tuner and a light foot. Others have not. An exhaust upgrade also helps, because the stock exhaust is somewhat heavy and restrictive (from what I've read here)....

However, it would most definitely be a couple of years before you get your money back if you were to invest in all those mods..

5.6 V8, almost 6000 pounds, don't complain, I wish I got 15 MPG!! Only way to do any better is to park it!

Simply.., get off the throttle. CAI.., comes with one from the factory, draws air from left front fender area, no engine heat there. If you want to do better, use the cruise control as often as possible and drive at the very least the speed limit and I like what the previous post said about driving like you have an egg between your foot and the pedal.
