FUELER Posted March 24, 2010 Share Posted March 24, 2010 SO my buddy has a 2000 4runner with 3.4L V6. The first thing that shocked me with the 4runner is the fuel tank size. He pretty much ran it dry and filled the tank to the brim with only 13.5 gallons. A freakin Honda Civic has an (almost) 12 gallon gas tank. Then, we calc'd the MPG. Freeway driving at 75 mph, he clocked 271 miles on that 13.5 gallons, which equals an impressive 20 mpg Now my QX4 has a 21 gallon tank (which, in the past 6 years of ownership, i have only managed to get about 19.5 in there) and i get about 290 miles to the tank. 14.8 mpg similar freeway driving. WHY DOES THE NISSAN GET SUCH WORSE MILEAGE???????? Maybe i should have bought a 4runner.... but the idea of bolting on cookie cutter parts and having the same SUV as everybody else makes me cringe... Your thoughts on this?? Link to comment Share on other sites More sharing options...
Toby Posted March 24, 2010 Share Posted March 24, 2010 14.6? Are you serious? I've been averaging around 21mpg on my WD21... That's weird. Link to comment Share on other sites More sharing options...
Precise1 Posted March 24, 2010 Share Posted March 24, 2010 My old stock, manual 95 would average 16-21mpg. My new modified auto 95 gets 14mpg around town (no long trips yet and I think I have an exhaust leak) and the stock 99 R50 gets 16-19mph. No one ever said they were made for commuting...

nunya Posted March 24, 2010 Share Posted March 24, 2010 #1. You ain't stock... is the 4runner? Could affect your mpg's a little #2. "similar" driving ain't exact driving. Your 70mph may be a little more harsh than his 70mph if that makes any sence #3. aerodynamics are a little different from a r50 to a 3rd(or 4th, I don't exactly know where a 2000 4runner falls)gen Toyota #4. My 2gen Has some of the same j/y tricks as wd21s #5 Mt. Dew is yellow Link to comment Share on other sites More sharing options...

silverton Posted March 24, 2010 Share Posted March 24, 2010 I notice you have beefier tires. Is your speedometer calibrated for the change in wheel/tire size? If not then your odometer/trip meter reading is going to be off, sometimes by a lot! Link to comment Share on other sites More sharing options...
veilside180sx Posted March 24, 2010 Share Posted March 24, 2010 I get 18 city / 22 hwy in my WD21 with 31/1050. I don't think that his 20mpg from the 4Runner is anything to shake a stick at. Link to comment Share on other sites More sharing options...
laxman0324 Posted March 24, 2010 Share Posted March 24, 2010 My 97 with 31's would get 21-22 on the highway all day...now my 01 is a different story, with 31's I have yet to hit 20, almost always right on 19...I have heard of 4runners getting crappy mileage too, for some reason some just get good mileage and some get bad mileage...

adamzan Posted March 24, 2010 Share Posted March 24, 2010 If it is tuned up and running properly, it is all in how and where you drive it. Link to comment Share on other sites More sharing options...
Kingman Posted March 24, 2010 Share Posted March 24, 2010 The 3.0L 4Runners get horrible mileage, bad enough to make a Pathfinder look good. My friends '95 3.0L gets about 16 on the highway and 11 in town. Another "friend" of mine has an '01 with the 3.4L and he said he gets about 16-17 in town and 22-23 on the highway.

nismothunder Posted March 26, 2010 Share Posted March 26, 2010 #5 Mt. Dew is yellow Best damn post in a while nutya... I say gear ratios play a big diffrence,I dont know what the yota or that style nissan is running but if I remember correctly the best(lowest you could get in a yota that wasnt a trd is 3.73,while I think the 'sans still a 4.3...

FUELER Posted March 26, 2010 Author Share Posted March 26, 2010 Yeah ive got bigger rims and tires while my buddy rolls on little bald street rubbers i should mention ive had a bad O2 sensor for years (after the cat). I thought after the cat was for smog only?? Or could it affect my MPG? Link to comment Share on other sites More sharing options...

nunya Posted March 27, 2010 Share Posted March 27, 2010 #4 means what now?? B Was just an observation... not all 4runners are cookie cutters like jeeps... Although he is comparing to a newer one. I gotta call BS on #5 I just call em how I see em... even if I don't dring Mt. Dew... The 3.0L 4Runners get horrible mileage yes, and are a bit gutless to boot, once again he is comparing to a bewer one though i should mention ive had a bad O2 sensor for years (after the cat). I thought after the cat was for smog only?? Or could it affect my MPG? another factor that is hurting your mileage... Link to comment Share on other sites More sharing options...
InfinQX4 Posted March 28, 2010 Share Posted March 28, 2010 Fueler, I think we went over this a while ago, but MPG is not good on the Q. Can't say much for the 4Runner, but I average about 14-15 in overall, mostly highway driving (70-80 mph). Did notice that the closer to 65 I stay, the longer the gas lasts. There is a huge difference between mpg going 65 vs 80 mph. Funy you say that about the tank - come to think of it, i've never put more than about 19 gal in it before. and i've run it really low...or so i thought.

Tungsten Posted March 28, 2010 Share Posted March 28, 2010 (edited) One of my buddies own a QX4 which I somewhat dislike. It gets about 16 mpg and its completely stock. It is normal, the QX4 sucks. My modified '91 Pathfinder does 25 mpg highway and 18 mpg city, I have a similar setup to B's (Precise1) truck. PS: If you want better MPG, use 2wd ONLY.

(supposed to be 21 gal tank?) Link to comment Share on other sites More sharing options...
silverton Posted March 31, 2010 Share Posted March 31, 2010 My last two "fill ups" have netted me ~20mpg, and that's mixed highway/city. Link to comment Share on other sites More sharing options...
Tungsten Posted April 1, 2010 Share Posted April 1, 2010 Maybe it has to do with the strainer design on the fuel pump? What about the reserve? The only way for you to be sure that the tank is bone dry is to actually look inside it. Link to comment Share on other sites More sharing options...
silverton Posted April 1, 2010 Share Posted April 1, 2010 there is the possibility of sediment built up at the bottom of the tank as well. Link to comment Share on other sites More sharing options...
InfinQX4 Posted April 1, 2010 Share Posted April 1, 2010 There are a few possible reasons. More of a curiosity than something that really concerns me. I’d rather work out a way to carry some Jerrycans around then spend the time wondering what happened to the missing gallon. Link to comment Share on other sites More sharing options...
