What's your MPG (fuel economy) on the road.

1994 Dr T Land Cruiser, 1FZ with 230,000 miles. I get 12 mpg no matter what. Uphill, downhill, headwind, tailwind, loaded, unloaded. I guess I should be happy it doesn't get worse, but I wouldn't hate it if it occasionally got better.
 
Oh I'm jealous of the Taco guys getting above 15 MPG. I'm currently at about 12-13 MPG on the highway (she's a fat pig for sure). But to be honest this thing has never really got above 17 even when brand new.

If I drive like a Texan I am getting 18 mpg cruising down the highway. If I drive like an old man I get 22 mpg on highway. When pulling a 27 ft travel trailer I was getting about 10 mpg. On trail is a question of trail conditions.
 
I'm a fairly conservative driver on the big road (well, back roads too, but OP asked for 'highway to the trail' figures) and regularly get 20-21 mpg with my 6.6 Duramax diesel. DIC says higher, but my figures, based on stock config, real mileage, and actual fuel consumption, backed up over a few hundred thousand miles worth of receipts and figures, tells me it's a bit less than the DIC says.

She absolutely loves staying steady at 65-70 for long runs, and long as I'm not all over the place in braking and accelerating, or gunning to pass others, I'll go 500-550 mi before I need to fuel up again. Specs say I have a 31 gal tank, but that Low Fuel light comes on long before that, must be around 5-6 gals left. Most I think I've ever squeezed in there is 28gals, and that after running a long ways with the low fuel light on. I usually have extra fuel with me, but haven't run the ol' girl dry yet.

Getting mileage and range like that, loaded or unloaded, along with the vast cargo capacity (317 cu ft, I think), is a large part of why it is my preferred DD, on or off-road. I suspect my mileage is going to drop when I start hauling a trailer regularly, with a RTT and awning. I hear you're supposed to pack all that s**t up before hitting the highway. . .

2008 LR3 with 122k, 265/70/r18 (32.6). The ecu and spedo have been recalibrate but who knows how accurate that is. Mixed driving to work I get 18 averaged over the week. Best I've gotten over a long highway trip is 23 (Texas to NC). Towing the boat, loaded with gear it's in the 13-15 range.

The real downside is it needs to be top tier premium, no Race Track or Valero. I've used cheap 87 in a pinch a few time but the dash lights up like a Christmas tree.

2004 Jeep TJ - 27 mpg on BFG KO2's (30X9.5X15) at 70 mph
Try miles/gallons=mpg next fill up and post your results. I think there will be a slight discrepancy. Unless you are sporting a diesel and a strong tail wind. How many miles do you get per tank?

2016 F-150 with the 3.5L Ecoboost:

Stock, Mixed driving Road trips = 20-22 MPG

After level and 295/70r18 nitto Ridge Grapplers, mixed road trips = 18-19 MPG

Rig with full expo load out, after 1500 mile trip offoard and on road = 15.5 MPG

(all hand calculated)
 
I usually get about 13 MPG (94 Land Cruiser FZJ80) running Toyo 265/75R16 with everything else stock except for a lift

Took 7 people with all of our stuff on top to the Del Norte area in Northern California and with all of this crap on top, STILL got 11.8 for the trip!delnortecamping.jpg

Today, I upgraded to 33" Muds - curious to see what I get....

My 2000 LX 470 gets 14-15 on a combination of hilly back roads and highways. Just pulled a trailer 1300 miles, got about 8 mpg with the trailer empty doing 78 mph, added 1000 lbs and drove 70 mph and got 12 mpg. Weight of load seems to make little impact on economy, but speed and aerodynamics are huge.
I have no idea what it gets in the city, because I don't spend much time there. Don't know trail mpg because I haven't found a trail long enough to need that info here in the southeast.
My 96 Montero SR used to get 19 "backroad/highway combined." Currently it seems to be getting about 10 mpg; that and the anemic power tell me maybe something might be wrong with it.
Both vehicles are pretty much stock.

My 2007 FJ Cruiser gets between 14 to 16mpg on the highway. I have 235/80-17 BF Goodrich AT's, stock roof rack w/ Baja Rack drop-in basket, Road Shower v1, rear ARB awning, Yakima Roof bars w/ single bike holder.

Aloha from the PNW,

Last summer we did a 3000 mile trip with a Pop-Up Tent trailer (3500# loaded). Speeds varied between winding roads to Interstate highways (60mph to 80mph) and we still got 13 to 14mpg.

I am still crunching numbers on fill up but seeing consistency. 1989 Toyota HJ61 land cruiser. Think my speedometer is accurate. I have been matching the kph to my gps in mph. So my odometer is probably correct. The results are around 30km/gal approx. 19m/gal. I am thinking not bad.

Last weekend a friend and I drove to Oregon for the eclipse. I was somewhat surprised to see 20-22mpg on multiple tanks of gas, this was based on a calibrated ScanGauage and confirmed by hand calculations. These tanks were all highway and we were averaging 65-70mph.
