When I drove my 97 LX450 back to CT after purchasing it in WV, on the 450 mile trip I got 16.5 MPG. I went 307 miles on the first tank before filling with 18.5 gallons to full. Truck is bone stock.
I have been pleasantly suprised with the gas mileage so far.
Agreed. Get a ScanGuage, and all your questions will be answered.
I get about 15 on highway trips. Sometimes better, but sometimes worse - one factor people don't calculate is wind. A head wind will cost 1-2 mpg easily and you may not be aware you're pushing through it. Also the subtleness of slope is a huge factor. Spilling off the eastern slope of the Appalachians or Rockies is a huge advantage, conversely approaching a continental range is a slow but steady load on mpg. In the last 4 months I've driven Maine-Florida, Maine to Ohio, Maine to the Outer Banks - 15 mpg is a fair assessment for me over those 10,000 miles.
Agreed lots a variables. Plus some may not be factoring in tire size which is throughing off their odometer. Any way I am running 305's with the correction gear. Light usually comes on around 300 miles and I have drove a max around 330 with the standard tank. i consistently get 15-16mpg haulin ass up and down mountains passes. These numbers are probably 80-90% highway but they drop off significantly in town. I had a huge problem with this coming from a 70 series (450 miles or so per tank) but that will no longer be an issue soon...
This kind of thread will eventually lead to post traumatic stress disorder...
Just to add to the cacophony, my best so far is 320 miles on a tank hwy, stock but somewhat loaded with wife, kid and camping cräp.
all i know is my rig is one thirsty pig.... at least she only takes 87. i have yet to do a long road trip to gauge some actual highway mpg, but around town it seems i'm getting 12-14. about 280 on a fill up of 20 gallons.
When my rig was new (to me- it had 32k mi. on it) I was getting 320mi. or so per tank. Now, after 5 years, 68k. mi. more, new cap/rotor/belts/radiator/plugs/wires/pcv/fuel filter/modded fan clutch, 33" Revos w/ correction gear, ARB winch bumper (w/o winch), OME 850/860, removed roof rack, I get around 230-240 before I see the light. That is a huge decrease. I noticed I got a big decrease after I added the modded fan clutch- went from around 260-270 to 230-240 mi. per tank of gas, and I can definitely feel the power drain. On the other hand, my temps are a lot more stable at 186-190F 95% of the time.
Live4Skim- you mentioned seeing an MPG decrease after adding your stereo equipment. What kind of stereo equipment are we talking about? Enough to cause a serious drain on your charging system? I've added a few pieces of gear, and I'm beginning to wonder how much of an effect that has had.
2100 ft elevation, 2.5" lift, 33 Goodyear MT/Rs, rear storage box, ARB front, Hanna Sliders, about 220-240 when the light comes on. 210 when I've done more street driving.
This 250+ is surprising, the 300+ answers are unbelievable!
Agree a 'per tank' thread like this is about as next to useless as I can think of to compare economy. Fill your tank a gallon later than someone else does and boom - you're thinking you have a problem. The only way to discuss this issue is with properly calculated fuel economy. When new, my truck got 16-17 on the freeway, now it gets 15-16. Cdan has a complete accurate FE measurement over his truck's entire life, I believe.
Good point, Doug. When my truck had 32k. mi on it and was stock, it was getting around 15-16MPG highway. Now (with mods listed above in prev. post) it gets around 12-13MPG highway.

I can get 320 out of mine - but I'm never able to fill more than 19.9gal or so. I've done a 155 mile tank filling 19 gallons before.
My average over a year and a half (17000 miles) is 13.15mpg.
I'd imagine the majority of gas mileage depends on driving habits. Since I lifted/33'd I've gotten better gas mileage overall, but that's just because I've been very easy on the truck.
I live around 300 ft. above sea level.
Mostly freeway driving I am getting about 250miles till the light turns on.
I dont let it go much further then that.
With Cruise Control on I can get a few more miles then letting my foot work the fuel.
Other then that it sucks in the MPG.
My buddy put a cummins diesel 4 cyl in his 80 and is getting around 22MPG.
I get 220 miles for every 16/17 gallons (to the quarter) of gas. Right around 13.5/14mpg, mostly city driving. Probably get around 15mpg on the the highway. For those getting 300+, kudos to you. Mind sharing the secret??? Diesel? Gutted? Do you get out and push sometimes? Combo of all three?
I get between 9 and 10 mpg, with my best tank at 13.
