Increase in gas mileage 3.7
At 5,500 miles, I have noticed a 2mpg increase in mileage of my 3.7 Screw over the last 2 tank fulls. Not sure what the cause is as I have not changed my driving habits and I can't trace it to any particular station as I have filled up at two differant places the past two times.
I've been averaging 16-16.5 since new but ended up at 17.9 on the last tank and am at 18.5 on this one with about 50 miles to go. Very pleased

I now have over.......`
21,000 miles on my 2011 Screw w/ 3.7 and a 3.73 rear...... have averaged about 19.4 around local driving in semi-rural florida..... and still get just about the same to perhaps 20 out on the Interstates at about 72 MPH. Seems like if I baby it a bit I can coax 22-24 out of it if I keep the RPM's at about 1500-1600 and do about 60-62 MPH...... but it sure drops when I hit hills and/or punch the revs up a bit to the 2,000 or more mark...... still not bad for this truck but I was aable to obtain a steady 20 MPG in my old '98 XLT with the 4.6 engine....... with 100,000 on the clock.
