      Hi All,

      Just wanted to share my recent fuel economy endeavors !

      After I bought my 2007 EB 4.0L explorer a month ago I noticed it consumes lots of gas compared to my friend's expedition of the same year. We both fill up our tanks and mine dries first and he still has 1/4 or more to go.

      I normally get 10 mpg average and 14 mpg highway (with AC ON). The car drives nicely and has been serviced recently(oil,air,sparks...). A google check brought up injectors, tyre pressure, MAF ...

      I started with filling each tyre with N2 @ 35 psi. originally they had 40 psi of air so was not expecting much mpg benefit. surpassingly it worked and I got 0.5 mpg increase despite lower pressure, and yap the ride is much better now!

      for the injectors, visited the dealership to get some injector cleaning fluid and it worked ! got 1.5 mpg increase, so might need to mechanically clean these,

      the car now gets 12 mpg average, not much but its better than 10 ! the MAF is next ...:)

      cheers !
