    you are way off. go back to basics. have the fuel pressure checked to see if you may have a leaking fuel pressure regulator that would drastically effect your mileage. could be that simple.

    Hi>, The problem(s) you've mentioned "could" be attributed to the fuel/gas you're
    using. Some of our gas stations in the NE U.S. have "problems" with trying
    to keep water/condensation from accumulating in their underground tanks.
    They don't filter out water from the gas before you pump it in your tank....so a
    higher than average moisture content (water in gas) will cause the same
    situation. Check with other drivers at that station. - callhow

    I have had a service station for many years in the NE and there are several filters for this. granted, it will not be 100% effective but does get most of the contaminants. If this was the problem, then a lot more people would be effected and the service station would be bombed with complaints about this issue. I still think a back to basic approach is where you need to start.
