I'm curious here....I'm gettin' about 16-17 mpg with mixed mountain(city) and freeway driving...but that is with me not pushing the gas past 1/4 throttle, at all, barely 1/8th throttle...once i start giving it more gas, it drops to the 14-13 maybe even 12 mpg range...now, what i want to know is:
1.) does my milage seem normal?
2.)what is everyone else's mileage out there?

Now, I have a "custom" high flow cat...lol....drilled airbox mod, k&n air filter, and a flex-a-lite black magic electric fan...everything else is stock....my vin says i have 4.56's, but my freeway rpms tell other wise, they act like i have 4.88's....im crusin at 3k rpms @70 mph....shouldnt i be around 2700 rpms if i had 4.56's?

Anyways, what im trying to say is....i wanna hear your MPG on your rig, perferably 4runners,but other vehicles are welcome as well....list all of your mods, re-gearing ect....

Vehicle - bone stock 2002 4runner SR5 4x4 auto with <60,000K miles

Avg - 17-18 mpg
Best - 20.5 mpg

Details:
I just did a trip from Park City, UT to Crested Butte, CO and got 20.4 mpg and 20.5 mpg on two different tanks - that shocked me. That drive is mostly 55-80 mph with some flat highway but also a lot of high speed mountain driving.

That is considerably better than the 17-18 mpg I usually get with my local driving (town, little highway, and often towing of a snowmobile up the mountain to the trail head).

I think my numbers are pretty good given the spec of 16-19 mpg (I think that is what it is) for the 3.4 V6. I am getting the same mileage that I got out of my 1993 22RE - but that thing was SLOW.

I never owned a 3.0, but your numbers sound ok to me. You should add the total mileage on your engine to your post. If you have 180K or something, I think you are doing pretty well. Certainly others do worse. <img src="/forums/images/graemlins/kewl.gif" alt="" />

I get something like 20 around town and 22 on the highways with my 3.4L.

oh ya...forgot sorry....i've got 171k miles on her...original engine <img src="/forums/images/graemlins/smile.gif" alt="" />

15 in the city and like 17-18 on the highway, COrunner93, i envy your work, i will be there someday i hate my 3.slow.

yeah.....I'm soooo much happier with the 4Runner now.

I'm getting around 17 mpg around town and 19-20 on the highway with my 88 3.0 5 speed with 32" tires and 2-1/4" cat-back exhaust. Oh yeah, 142K original miles on untouched engine(other than timing belt). And it still has the original cat which I want to replace.

Mine has had issues since I bought it: 1984 4 cylinder with 40k on engine, new carb and fuel pump and filte wtih a K/N. I'm getting 11-13 in the city. No one can figure out why. It's running waay ricch I know but no mechanic can seem to fix it. I'm going to try to lower the float leve. On the freeway I'm at 15-17 mpg.

You replace the AAP on that carb yet? IF your dipstick smells like fuel, you should.

Anywhere from 15 to 18.5 average mixed driving. <img src="/forums/images/graemlins/scared.gif" alt="" /> Never checked it strictly for highway driving.
