knowing what my mid size suv gets, id say 40 is really up there.
looking at major aro mods to get that.
doable yea, but no cake walk.
mine is about 4,300LBs with 4.55 gears, 450LB engine and really bad aro. 33mpg is as good as ive gotten.
that's in flat land in warmer temps....with no cargo.
its old school diesel with a turbo added at the factory, so its not ideal as far as the power band, its rather narrow.....2,300 to 2,800rpms its very much suited to the gearing they put in the autos....and the fed 55 speed back in the day..
29 mpg is common as a year round avrege, running at 60 or less, with many steep roads day in and day out.
its rated at 28 city 28 highway
un like your jeep, im limited to 4.55 or 4.11s with the stock axils in a 87 or older ZOO.
my aveter is one of my loads, it sucked mpg down to 17. CGVW was about 9,000LBs, thus why i stay with the 4.55s
for the jeep if i remember right there's many different 3rd member gears that fit the dana 35 that the jeeps are common with.
