I have a new 3.5 SE, and my mileage is really lousy, roughly 280 miles (~14 mpg) for a 20 gallon tank. is this due to break in period? i read through a few forums and people roughly range from 18 mpg to even mid 20's. I do not drive aggressively, sometimes going to 3000 rpms when needed, but often staying around 2000. Any advice?
are you driving in drive or overdrive,od on off switch oh shifter will be a push button try this.are you city or open road driving.city driving stop and go will afect milage.no break in period is required.
This is correct, there really is no break-in period per se, but your mileage WILL improve slightly as everything begins to wear in. You don't mention how many miles on the vehicle? You may also want to have a dealer check it out, it's possible there is a faulty sensor or other issue causing poor fuel economy.
