Record mpg?

I've seen over 16 mpg a couple of times, with 16.75 mpg as best effort. Won't happen again now that the mods have started:p

Once the light stays on, I can squeeze about 22.5 gals into the tank. So effective reserve is about 10% of full 25 gal capacity.

YMMV:)
 
Since gas prices have hit over $4 a gallon here I have been driving like an old lady 55-60mph. I went from 11-12mpg to 13-14mpg and am happy.

If I lived where it is flat I could do better but in San Diego there are a lot of hills that eat gas.

Almost no one has the discipline to truly drive with a light touch at every stop/start, and to truly drive 55mph on the hiway day in and day out. If you do, then 16-18mpg is do-able. :meh:

That said, my 92 seems to get a couple miles less per gallon than my 91, even though they're both stock.

I totally agree, it takes discipline and patience to get that kind of mileage. The best I've ever got was ~17.5 MPG in the S/C 97. If you have a scangauge you can see real time just how much these things suck down leaving a stop light, at speeds over 60 MPH or from a down shift on the freeway. You really have to feather the pedal, coast to stop lights and keep your speed at 55-60 on the highway. Don't be surprised if people angrily pass you in town because you aren't gunning it from a stop light like everyone else, or if you are being passed by semi-trucks on the freeway.
 
My stock rig made it from Island Park ID to Highland UT on one tank. We calculated about 15mpg.
 
its much much easier to see how low you can get your MPG, ill start, a few tanks ago i never left the city for one whole tank, i drove 176 miles and put in 20.XX gallons 8.8 MPG FOR THE WIN!

I wonder if one was to use 255/85R16 tires that the mpg would increase even more ? hence a thinner tire, less power to lay down, right?

My cruiser with stock tires laid down 19.7mpg hand calculated on a short tank (100 miles)

I haven't done above 17.5 mpg with my current 255/85's. The best fuel economy tire would be a 235/85 Highway terrain maxed out at 80 psi. I am confident you could see 21mpg on a stock height rig @ 50-55 mph.

235/85's look ridiculous on an 80 but they just might be my next tire on the 80 albeit AT and not HWY. I will be the first to hypermile an 80.
25mpg here I come!
 
I consistently get mpg's in the 16.75 range as confirmed by fill up an dmath and also ultraguage....Stock tires and discipline makes it that way...pretty much speed limit wherever driven.
 
Early last month I bought my 1995 Land Cruiser, completely stock, tire size and all. Last weekend I drove it on a trip from Austin to Dallas and I was getting a sustained 19.1-19.3 average mpg according to my Ultra-Gauge. I was cruising at about 65-70 mph the whole time, sometimes using cruise control, sometimes without when traffic slowed me down. I was in disbelief, because the '91 my parents had when I was a teenager would get 14mpg on a good day -- didn't think the 1FZ would make THAT much of a difference in fuel economy. This was also driving into a 5-10mph headwind!

I thought there was no way that was possible, but when I filled up my tank again in Dallas the Ultra-Gauge reading agreed with the odometer/gas pump and it came out to be 19.1mpg.

For the ride back to Austin, however, the wind had switched directions, and seemed to be blowing out of the south at about 20mph with 30mph gusts. It was a really twitchy trip, what with the LC having the aerodynamics of a barn and all. Still managed 15.3mpg though. I don't know what kind of black magic was done to this truck before I bought it, but everything seems to be stock.
 
I usually average 210 miles out of a tank(I always fill up when the light comes on) which is roughly 20gal.

I did get 17.6 once, and I got an amazing 20.1mpg driving 55mph for 120miles(via scan gauge).
 
I routinely drove mine between Omaha and Denver throughout the last year and was able to average 14+ every trip at 75 mph. At some point I stopped calculating, but the gas station at North Platte was 280 miles from both of my destinations, and it always took between 18-20 gallons.

Stock tire size and gearing btw.
 
I just did a wheel bearing repack on ours (front and rear) finding one BAD front outer bearing. After the service I swore that it rolled farther when you let off the gas. Then the first tank yielded over 2mpg better than we had been getting. Up to 13.7 now, I'm stoked...
 
14.7 on the highway driving like miss daisy doing 65 70mph 85 octane with 10 percent ethanol 37s full size spare J springs with spacer on front me and wife and fat germen shepherd, no third row seats, all new vacuum lines and pvc timing set recently 5.29 gears

I love it!!! the :beer: truck tailgated me on the way home from work! Until they quit gouging us on gas I aint steppin on the skinny pedal pal! Granted it would suck cause I have blood sweat and tears into my current rig but a rear ender by the beer truck would hopefully by two land cruisers.

That's one reason I went with the 255s vs the fatter 285s. I doubt it's a huge difference. But it's squeezing all the things you can that gets you the best mpg.

Obviously, we wouldn't have bought an 80 if we were really worried about gas mileage.:doh:

Yeah, my recorded low mpg is 8.8, too, coincidentally. I have kind of quit worrying too much about it and, yeah, 'wheeling it is going to come up with even lower numbers.
 
My best was 13.3 MPG coming back from Tahoe last year with a serious tail-wind. My most-recent worse was heading up to Tahoe with a heavily laden rig with skis on the roof and a 20+ MPH head-wind = a whopping 8.7 MPG. I won't mention what it costs to fill the main and sub-tank with Kalifornia gas prices now...too depressing.

:cheers:

It is VERY VERY expensive to fill up with a sub tank here in SoCal. 38 gal total capacity.

I'm lucky to get 14mpg downhill! Usually 8-10 city and 10-12 highway. However, my average is about 9.6 to 10.1 MPG

Dan is right, alot of hills in San Diego and crappy ethanol gas here makes for bad MPG in an 80.

For those that are quoting higher MPG and are runnning larger than stock tires, is your speedo gear corrected with correction gear or a Yellow Box?
