I know there are a bunch of threads on gas but I have a 2009 2dr Sport with 35s, 3.5" lift with 3.21 gears and was getting 15mpg. Lately it has been declining pretty rapidly and this last trip was all highway miles and I was getting 11.5mpg. I was driving around 70 and RPMs were around 2100-2500 depending if I was in 5th or 6th.
Questions.
Does tire pressure make a big difference on mpg? Running 30 right now but had it up at 35 at one point.
Will gears help out much?
I also have an issue when filling up gas. At times I can only pull the handle 1/4 otherwise the nozzle will turn off as if gas is full. Could there be an issue with vacuum/pressure in the tank causing issue with mpg? Might be a stretch but curious.
