15mpg city/highway thats turning 35X14.50's with 4.88 gears... so not too bad for a 9" lifted truck with huge tires and a tiny engine....

 

wow, so lucky
I had the engine rebuilt at 20k ago, and I only get about 12 still. Runnin an auto, a few mods. These polls are always interesting, and every time they come up, I want to go kick my runner.

 

13mpg goin to and from work and daily driving. 3.0L 3vze auto. on the highway its been known to get about 18 on long trips. about 20 minutes ago i just got done welding a new catalytic converter in, it was way bad. clogged and starting to melt. we'll see how she does after this.

EDIT: oh yeah 31x11.50 mt's

 

Wow, I get 16-18 a tank depending. And I haven't even put wires and plugs in yet.

I can't help but notice a few of the low milers are California Control Vehicles.

 

3.0, 35x12.5r15

Just did plugs, wires, fuel filter, etc. and it's been about 15 lately.

 

I dont drive like a granny and im getting 19-20 mixed city freeway... and thats with a huge roofrack, stock 4.10's and 33x12.50's i guess the manual hubs and tranny make a difference

 

I just can't see how this is possible.
I've had two 3VZEs now, over 300,000mi combined and neither would get 20mpg, not even downhill, with a tailwind, drafting a semi.

My current POS w/ 4.88s and 305/60/18s (about a 32.5x12 street tire) gets about 12mpg, that's interstate too, it's worse around town.


I'd sure like to know what your trick is.

 

3VZE Manual Transmission: 22 mpg mostly Highway miles, 235/65/15s. Average speed 65-70 mph.

 

holy s***. im getting a whopping 12-13 mpg both highway and City. And I never even go over 70, I probably get 11 mpg if I go over 70. Do you think I need a tune up even if its not idling rough. I mean the idle is glass smooth right around 600 rpm. Distributor cap does look kind of old(its a Denso, which I think is factory). I'm running everything stock except for a grille guard. my mom's landcruiser gets better mpg than my 4runner. She's even thinking about selling it and getting me a camry or something. I would die if she forced me to drive in that. what do you guys think.

 

I think you are lucky to have a mom that cares... lol.

Otoh, spend some time searching. If your idle were 500rpm, I'd say that is the classic symptom of a TPS problem. There is a ton of info on this site.

 

I did my first mileage check since swapping out rims/tirers, plugs, cap, rotor, and plugging EGR vacuum line. I drove approx 90-100 miles on pavement going no faster than 65, mostly 60ish on cruise. I also had 60-70 miles on hard packed sand doing 40mph on cruise. I have manual hubs, auto tranny and stock 4.56 gears. my tires are 265/65/17's (same as a 32 incher). I got 15.75MPG. That was with a surfboard on top too.

 

3.0 4runner
auto
stockish

best- 23.9
worst- 12.8
average for me is mostly city driving- 16

(edit) the check engine light is always on

 

Get bigger tires.
I was getting the same with my 31's and 4:88's, I put 33X12.5's on and I am at 16.5 mpg (Auto trans. also). I did the math based on a 140 mile round trip and filling up not based on the tripometer (tire size effects that along with gearing)

 

im gettin about 16-17, but was getting 20-21 on a good week but the 33in tires were sooooo tempting i couldnt help myself.

 

I was gettin around 11 to 13 before my headgasket went. Thats with 31X10.50s and 4.88 gears. Hopefully it will go up after gettin all fixed. Also have a set of hubs comin in sometime. YAY!

 

could your gear ratio have a significant play on this? I mean by a couple of miles?

 

With 35s and 4.10s I get like 10mpg.. LOL.

When I put the stocker road tires back on (actually a tab bigger than stock) and go on long trips I get like 20-22mpg on the highway. Not bad. Remember this is with an SAS too so alot of added drag there, if it was stock height my MPG would be even better.

 

I will add that when I picked my truck up in Dallas and drove the 500 miles home like this, I got 20-21MPG. And I was driving 70-80mph. Have never gotten that since...

 

when i got it-18 in city, 16 on highway, i do like 85-90 on the highway thats y its lower

now after FIPK, full tune up, and new cat and exhaust-22mpg or more in the city, not sure about highway, but well find out after my trip into pa this weekend

 

I run a steady 16-18mpg with every fill up on my truck. I'm running 33x10.50s with a custom cat-back exhaust, Cootees ISR mod, and K&N filter.
