I have a stock '97 Supercab I just bought with 95k on it 4.0l OHV and an auto tranny...we just took it on a 2500mi round trip to Seattle and I was jazzed that with the back loaded up and driving an avg of 70-75mph we got 20.8mpg.
This is my third Ranger (4th if ya count the 87 B2000 I had) and they have all been great. But I was expecting much lower mileage then we got, more like 16-18mpg.
All I know is the oomph this motor has makes me wonder what took me so long to buy one! Even if it is almost 10yrs old, the thing drives like new...
I might try one of those Tornado thingy's though...do they work or is it just, well, good marketing?
