          Maybe someone is syphoning fuel?

          I can't remember if it was this forum or another one but the guys next door neighbor would syphon the gas out of his and his wife's car!!!

            theres something that blocks it in the 6. and for me, city driving jus kills my MPG.

              Check your tire pressures. Oil change? Air filter?

                  On my base V6 I only get about 250 miles on a full tank and I don't drive it hard.

                      especially the air filter. When dirty it can suck down your mileage as fast as one of those gals on 10th Avenue

                        lol, i probably do need to clean the filter. im sure that CRAB filter will suck up more dirt than others with the open box it has. i guess i was just used to driving all highway with it, and getting 30-35mpg with it.

                            Highway vs City driving will do it. I see a large difference with the 3.6 engine between the two.

                              I just followed mine as well, as i was thinking that mine isnt getting the greatest fuel efficiency.
                              I got about 390km on my last tank of mainly city driving.

                              I have a Short ram intake with a CAB, and clean the filter only once a year.
