Gas Millage V6 13.5MPG
So I finally got around to checking my millage on my 2006 V6 4.2L with Procomp Lift 35s tires and 4.56 gears most of my driving is freeway with minimal AC ussage.
Was hoping for at leat 17........ 13.5 is pretty bad for a V6 this tank I only remember stoping on the gas hard 2 times to pass .......

13.5 is very bad for a V6 4.2... especially for mostly freeway. The lift with the 35's definitely doesn't help, but it shouldn't affect you THAT much... I have a supercharged 4.6 V8 and I can run about 14-15mpg average (equally city & highway)...
Anyone have any ideas to help this guy out?

If you have a GPS unit with speed readout and distance total, use that and check the mpg since the GPS should be right on due to signal triangulation. I would think having the 4.56 gears with those tires that you should be getting good mpg, at least above 13.5 mpg.

See if you know someone that has a portable unit that you can try out, do a moderately long test run so later you can calculate what mpg you are getting as well as how the GPS's speed readout compares to your dash speedometer.

That sounds about right. You may think having a v6 means better gas mileage but couple that with a reasonably heavy truck and gas is not as good as you might think. What was your stock gearing? I had 3.08 on my 97 and when I put on 35's I put in 4.56 which gave me an effective ratio of 3.90 which is more suited for city driving than highway. Also, as it was already mentioned, if you have not recalibrated for the gear and tire change, then it will be off by a percent varying with what your stock gears were.
