I got my 2014 Limited a little over a month ago. My current record is 509 miles. I think I'm going to beat it as I'm nearing the end of my current tank. Probably 70% city 30% highway. Always on Eco.
690 on a tank....Cleveland to W. TN a few days ago. Would have been better but I had a construction backup in Lousville for an hour. I tried to maintain 75-80 mph. 4x4 Limited Diesel ORA2.
Went on a trip to DC and went approximate 500 miles and the light never came on.. Filled it up around 536 (after the light came on) but could have stretched it even further but saw a gas station with a rediculus price so I couldn't resist..
Plus wifey saying how we are going to run out also pushed me to abandon my experiment.
I don't see how there is anyway to make a comparison on this. There are too many variables. Type of gas and oil, speed, terrain, driving conditions, type of driver, and number of miles on the engine just to mention a few.
Appears my longest single distance between fillups was 558 miles, but that was only a 19 gallon fill up. I generally don't like getting below a half tank before filling up.
Better to have it and not need it, than need it and not have it. I grew up being taught to keep the gas tank above half because of winter storms/hurricanes and the like.
I agree though when I'm on the highway I like to have at least a 1/4 tank. I've been stuck on the the interest several times before for hours and saw several people run out. By 1/4 tank left I usually need to get out anyways as I've gone 400+ miles.
2012 Overland Diesel 5 speed, I made it from Birdsville to Port Augusta, a little bit of side tracking, so over 900k's on a tank one day, fully loaded after a Simmo Crossing, spare wheel and jerries on the roof, over 500k's of that on the Birdsville Track too-lots of slowing and speeding up due to wash outs (track had been closed due to rain few days prior) , air con and cooled Seats blasting as it was 40°C. EVIC said I still had 160k's left 😀
The best I have seen was in our 2014 diesel Overland @ 1267km (787 miles) with about 1/8 of a tank left. Our 2018 diesel HA I seemed to average about 700 miles (~28mpg) on a trip to Vegas.
