My truck has been pulling 14ish MPG since I got it, except for one tank where I ran a bottle of Stanadyne through it and it had a brand new fuel filter, pulled 16.5 there. Been consistent around 14 since then. So my thought process is that the additive cleaned up a bunch of crap and clogged the fuel filter again. So I have two filters on order from PowerStrokeShop.com. My plan is to change the filter, then run some Bio through for a couple tanks, or run another couple tanks w/ additive through to clean up a bunch of stuff, clog that filter up, and then slap the other filter in and hopefully get back to that 16.5ish MPG range.
