I typically reset my trip meter each time I fill up, at the pump. However, I'm still on the first tank, so I haven't touched it. I also calculate by gallons pumped and miles driven.
) it is probably one of the only downsides of the new GX in our eyes. Although we already have the Wilco Hitch Swing for use on our other vehicles, I'm not excited about putting the spare on there just to fit the auxilary tank when LRA finishes the design for the 550. A pipe dream would be that someone came up with a replacement 26 gallon tank if the could make one fit in the OEM position. 
Have had mine on the west side of Houston. Haven’t seen mine that bad since taking possession in August. I was getting 15.8 around Houston. Took two road trips since mid November with the rig weighted up and I’m down to 15.4 at 7000 miles. The last trip (Houston to GA on Friday) was >900 miles on the highway and watched, and cried, as I saw it sink from 15.6 to 15.4 over that distance. Prevuosylt had changed the OEM roof rack, nothing up top, hung a cargo carrier off the hitch but that didn’t affect aerodynamics. Full tile
Ultimately ended up with entire 3045 mile trip avg of 17.8 mpg with included 6 days of driving around town and in the "mountains" of PA. We ran 93 octane all but about 3 tanks which were 91 octane when that was all that was available. GX was mostly in "Comfort" mode with a speed of 77-82mph with a good variation of hills/flat roads from Houston to North Central PA. Vehicle was always loaded with far more that 2 people and a dog need for any trip.Just drove ~1500 miles from Houston to North Central PA in my wifes OT. After owning it for 5 months she only had 1015 miles on it when we started as I am pretty sure she could have a bicycle instead of a car for day to day, but I did change the oil at 900 miles before we left (sent to Blackstone and waiting on results).
First of all we love this vehicle.
We have had zero issues and it's exceeding expectations on comfort, looks and capability thus far. We both walk away from it when parked as far away from any cars or carts at HEB and smile at the decision.
For the 20:48 hours of driving on trip it was in cruise between 75-80mph control enjoying everything about how much easier that assisted driving is. We averaged 18.2mpg for the trip with about a 50/50 split on comfort and eco. Not bad in my book considering we were loaded to brim with the Iceco, Christmas gifts, luggage for 2 weeks, an 80lb Weimaraner and all his gear.
Although it is refreshing fueling up cost wise with the tiny tank (anywhere south of PA fuel tax ubsurdity
Other side notes from the first trip:
Will update following the return home. Merry Christmas everyone
- Cool box works extremely well, but not worth the space it takes up
- WTH is up with climate controls? Still working to figure it out with all the S-Flow and Eco settings but so far it's a little wonky with all the hot the cold then hot again.
- Fold your mirrors in at speed to realize just how loud they are... my thoughts wondered on the drive about what kind of add-on modification will be designed to quiet that down, but fell down a 90's Madonna conically enhanced rabbit hole before being shut down by the GX reminding me to look forward in cruise.
- Get the Weathertechs. Although the OT mats are better than normal, no where close to the Weathertechs as far a coverage and looks.
Your dealer can turn off S-flow, and i highly recommend having them do that. The climate controls get easier as you get used to them. I now have my seat and steering wheel on Auto, and climate control is on Auto, so all I do is adjust the temp control as needed and the rest happens automatically.
For that mileage you must have been on the back of a flatbed going down hill. I have very little faith in the MPG or range tracker - my GX OT+ had 41 miles left on the range. You would think it must be almost empty. Filled it up and put 13.5 gallons into the car - which means there was at least ~8 gallons still in the tank, yet showing 41 miles of range.....
no way, mate.... just got home from my second long trip, Florida x Utah, 2 weeks, almost entirely on cruise control within the road speed limits, eco mode... that can't be real. sometimes I regret not having chosen the Landcruiser with its hybrid engine. I wonder about its real-world mileage... quick google search on reddit tells me 21/22 and above. I 'm seriously considering switching to it whenever my time with the gx gets closer to an end (aka financing is about 85% over )
