We got done going on a 5200 miles road trip in two weeks.. Stops were St. Louis, Denver, Bryce Canyon, UT, Las Vegas, Grand Canyon, Carlsbad Caverns, NM, San Antonio and Houston then back to Warner Robins GA. Van is my friends its a 1999 Ford E-150 with the 4.6. Had over 215k on it at the end of the trip. All fluids were new at beginning of the trip oil was QSUD 10w-30. Used 4.5qts on the trip which I don't think is bad considering the van was 7200lbs and we were towing a 2700lb trailer. Did the whole trip at 60mph no O/D there were plenty of long WOT runs in second in the mountains. Over all proof that with good maintenance mileage is just a number.. We averaged 11.8mpg for the trip. Just thought I'd share.
Us in Denver.
