There is simply no myth to it.....I used to consider myself lucky when I hit the 300 mark (reference my old thread about just this) before a fill up....NOW i would consider it a failure if I did not get 340+......Just a thought. Read any web page you want but my lifted VX is living proof.


Not only do I get more miles out of my tank but I would go as far to say the accelerator feels more responsive. To explain it, it feels like when I press the gas a fuller more sensitive pedal.....There is also the added benefit of burning cleaner and cleaning out your system...
