How many miles per tank of gas?

[firetruck41]

Talking about "miles per tank" is worthless. Every gauge will read slightly differently, they are not very linear, the warning light will turn on at slightly different times on different rigs, everyone's idea of a "tank of gas" differs, does it mean when the light comes on, or when you start to fear the engine will shut down any moment as it sips the last of the gas, or is it when you are stranded on the side of the road because you ran out of gas? If you want to talk about the health of the engine and compare mileage, then actually calculate MPG by filling the tank, then driving XXX miles, and refilling. Take the miles driven and divide by the gallons to refill, and there you have your MPG. Use the same pump and you will, maybe, be even a little more accurate.

I get between 170 or 330 miles per tank. I average 10-11mpg around town, with a high of 15mpg on the highway.

I'm afraid to do the math.

So I filled up today it took 16.8 gallons. I was just a hair above 1/4 tank when I filled up. So r u guys really driving ur LC that low on gas. I have always been told not to drive below 1/4 tank as it makes ur fuel pump work harder and can cause it to go bad early.

I usually wait until the warning light comes on, that is about 21 gallons on my truck, 4 gallons left means I could go 35-50 mile more... I have run it out of gas two times, IIRC. No problems, just put gas in and operate as normal. I wouldn't run it out of gas as a habit, other than that, I don't think getting low on fuel in the tank will hurt. If you have issues, you may need replace the fuel filter/sock.

Don't be afraid... choose not to...

I agree each may be slightly different. My light comes on with 2.5 to 3 gallons remaining and never flickers. It always comes on steady only. I've confirmed this many times by putting 22 to 22.5 gallons back in the tank. I would try it out on your own rig before assuming you have 5 gallons simply because someone else does. It is good to know what your rig does & could keep you out of trouble.

With that being said, around town I get about 200 miles, give or take 5 miles from Full in my main tank before the light comes on. All highway I get a bout 220-230 miles. I have 285's and the Slee speedo correction gear and alot of weight in bumpers and sliders. I also have done fuel system PM with a new fuel filter & ultrasonic cleaned the injectors .

Works out to about 8MPG city & 10 MPG Highway but that is all hilly driving and with a supercharger. When I lived in flat country, I got 12-15MPG without the supercharger and a slightly lighter rig at the time.

[SUMMIT CRUISERS]

On my 92 the light comes on at 220 to 225 with the stock 31's and 200 to 210 with 33's . MPG's in town driving 10 to 12. Highway driving 12 to 14. Stock bumpers, no sliders or heavy add-ons.

 

[TulsaCruiserClique]

91 rebuilt 3fe 11mpg.

 

[dgerst]

187 last tankfull. 20.6 to refill IIRC. Ultra-Gauge reported a little over 9MPG. Mostly really short in-town trips with lots of idling and maybe 50 miles of highway. I get around 15-16 highway.

 

[veeLC]

11-14 but still trying. It's a game really and I keep thinking what I can do to make it stretch. But I won't lose sleep over it and neither should any LC owner. Think of it this way...an M1 Abrams sucks gas like there's no tomorrow. TLC's are kinda in the same class I think...

 

[GIGGITY]

9mpg on the tractor engine ffffuuuuuuu

Out of all of that no one mentioned how a couple pounds of air in your tires will increase your mpgs on the road.
I get a solid 16 on a stock rig..300 to 350 miles for right around 20 gallons
The math says 17.5 if i make 350 . I run 275s at 40 to 41 pounds on the road

Now that I know how many MPG, about 170 to 220 I get out of my truck... I don' care. I knew these where no Prius, I traded a small pickup for the 60 and he 60 for this 80. Since the 60, I knew about the gas factor, and still don't regret switching to the Cruiser, as a matter of fact, I have 2 80's and they do get used constantly. So, gas use is not what matters to me, I prefer safety over fuel consumption.

10.5 mpg on last fill up - mix of city highway in sub zero temps and intermittent snow storms.

 

[desmocruiser]

85% around town, but only a few stop lights and numerous hills, 10-15 mile runs with 100% gas, no ethanol. I usually experience 5-15% less if I have to run fuel with ethanol.

97' S'Charged with 315 Toyo's 190-220 per tank.

96' Stock engine without recent tuneup and 285 Toyo's 200-230 per tank.

I think it would increase slightly with a change from the Toyo's since they are heavier than most other m/t tires on the market.

Oddly enough:

88' FJ 62 with 265 BFG's and 80 series steelies 200-220per tank

87' FJ 60 with 31x10.50's ~200 (first tank after rebuild and long warm ups in the AM)

I have gotten used to10-12 mpg and depend more on my trip odom than the gas gauge it is so consistent.

I have had my 80 series for 14 years. I have taken very good care of it. I change everything sooner than is required and have religiously done all scheduled maintenance. An average of 13 miles a gallon is about what you can expect in fairly level terrain. Given the design and intended purpose of the engine, I am not sure you can do much to improve on that figure.

Where you live can factor into your gas milage. I have lived all over the country in the last 14 years and my average miles per gallon seemed less in more mountainous terrain (I am now back to living in flat as a pancake but otherwise fabulous Dallas).

 

[Hovenator]

Just filled up. 17.03 gallons. 210.8 miles (corrected 5.4% for the 285's)
MPG is 12.4

That was mostly around town with one 50 mile highway stint. It looks like that is roughly the norm. I was a little concerned when I saw posts with 250, 275 and 300 miles on a tank.
I believe that my milage was closer to 14 in the summer. I think the "winter" gas must make a difference.

Ha! Very similar, 650kms city driving with 1HD-T & five speed, on 35s with FOR GEN II lift/armour FWIW!
