Here's another report.
Last weekend we went to Washington Court House/Greenfield, Ohio. I filled up at Greenfield and in a 287mi drive got 28.9MPG with three aboard, and enough crap to fill every square inch of the MM. I topped off at Washington Court House, and drove home via anouther route. The low fuel light came on just as the odometer clicked over at 400mi. Since I have a home tank, I can't give accurate MPG data, but nevertheless, I'm convinced that installing the Pro-Guard is the reason for the outstanding fuel economy.
