Well I'm still very happy with my results, though way short of what you guys are doing. Vehicle has 14,500 miles on it in 9 months of daily, winter was a killer on mileage but expected.
Since May, I think combo of warm weather and a broke in motor, along with full synthetic in the engine has helped alot. Get around 34-36 for my driving, computed with the In dash unit, so I know its about 3 % high.
Past weekend, played around some not in a hurry, had about 1.5 hours of some stop and go country-style, roads marked at 45-55 mph.
Did max 50, alot of 40-45.................... Ended up with a reading of 42 MPG on the Nav screen.
So I'm happy, I used to drive a vehicle that gave me a combined 18 for my typical routes, and have almost doubled that, granted, the 18 was in a Hemi, and this ain't no Hemi.
