fuel efficiency question

431 km???

I just can't believe you got that kind of mileage, and with a trailer, too.

Well, it's not typical. Usually this one gets 350+ consistently, so I was really watching the odometer and fuel gauge on the trip back. Cool weather, tail-winds, whatever... it was a real treat.

This IronMan has always intrigued me as to how much better it performs than any other 3.5L I've had. I got it off eBay with 99,500 miles on it and it's peppier and consistently gets better mileage than my bought-new '01 VX or the '01 2WD Trooper we just sold. The only non-stock driveline goodies are a K&N drop-in filter and all Mobil-1 lubricants througout. This is just one of those vehicles where the planets and stars were all in alignment during assembly.

I guess the only way to sort out all this variation is to get several of these VX's on a dyno and test under identical circumstances? Does anybody have a dyno they want to donate for this test?
