Ahh, good stuff. I will have to post as I just made a trip from my town of Braidwood, IL to Valley Head, AL. Roughly 620 miles each way. I had just greased my wheel bearings before leaving, I averaged 20mpg the way there. I'll say that it was a little more than 20, but that's a nice round number. It was very windy and not in the right direction. Eitherway, on the way home on the first tank I made about the same, on the second however I got a bit of cheap gas and was back down to around 15-17. But, all in all I saved a tank of gas which amounts to about $50.00 on that trip. Well worth the wheel bearing grease . I used to average 17 on the highway/expressway and about 15 in town. I've got an Automatic 4x4 2.6L 1989 Trooper for reference. Just hit 167,000 miles, headgasket was replaced at 155,000 if I recall. Still need to adjust the valves though .
