I know there are a lot of factors that go into FE. Things like speed, gearing, tire size, etc. And that all vehicles are different. Things like weight, aero, drive train (FWD/RWD/AWD), etc. And where we drive them most often, either in town or on the highway.
So where do YOU get YOUR best mileage?

at 45MPH = 40-45mpg reading on the instant gauge @1,080rpm
3.0L/6.0L V8 engine btw.. once it flips to v8 mode it drops to 25-29mpg but soon will shift back to v4 mode and 40-45mpg..
the best ever was 31.5mpg
I just reset my MPG average it's at 30MPG avg in 4 miles of travel..
the reason for resetting it as my suv have some issues with a dirty power cable causing issues with the engine. =poor mpg my fill up was only 18.9 but i did idle and short trips = lost mpg it probably would have been in the 22-25 mpg range otherwise
