Anyone else notice Ranger fuel economy went up?


Recommended Posts

Its a highway change, the biggest areas affectings that are...

 

1) aero (I don't imagine they've changed anything on the outside of the ranger)

2) Gearing (again, no apparent change)

3) Tire Rolling resistance (could have changed, don't know)

4) Engine Tune (perhaps electronic throttle control, new tune or ECU program)

5) Weight (way down on the list, but, I doubt they've lightened the vehicle any)

I remember a couple of years ago a panther engineer said they switched the panther rear ends over to synthetic gear oil because it improved the MPG by some measurable amount on the EPA test. They also tried the same with the transmission and mpg also increased measurably but because of the quantity of fluid needed in the trans, it wasn't cost effective. So synthetic fluids could be a possible explanation for the Ranger as well. They didn't really need to gain a whole 1 mpg, but gain just enough to round up to 27 instead of down to 26.
