    As a former hybrid owner, I can tell you it’s a bit more complicated than just swapping the engine. There is a huge battery pack and significant wiring that needs to be done. The perceived gain to mpg from a hybrid battery is not significant and certainly doesn’t overcome the cost.

    All around miles.

    7/8 MPT sounds like something’s wrong. Either you have a lead weight on the gas pedal or it’s time to start replacing some plugs wires and other things.

    really? for an 04 5.3? i drive mostly city miles. stop and go. i drive 20-25 miles daily. fill up every 5 or 6 days. still sounds wrong? city speed limit is 25. realistically drive 30 mph and faster on the highways. the truck is AWD. someone told me that makes a difference in the gas.

    7 or 8 mpg would be normal...if you were running a 454 big block. You got problems or are driving it like its a race car. (if thats the case, keep doing it and see how much it ends up costing you in repairs). The AWD might cost you 1 mpg over the 4wd version. I own (2) 03 5.3L and I average around 14 with mixed city (10 miles worth) and 55mph highway (3.5 miles worth) going to work. My 05 6.0L awd doesnt even do THAT bad. You getting a checking engine light? Replaced your air filter lately?
