After just driving my 3rd gen to and from work for 2 weeks, I managed to get a whopping 28 MPG on my AUTO 3.4 . Yes, I said 28 MPG! Thats quite amazing considering I drive the truck everyday BELOW 2300 RPM. I heard driving at around the 2000-2300 RPM range can yeild excellent gas mileage results, I geuss thats a true fact.

P.S. : My 3rd gen is all stock; no tires, gears, or lifts.....yet. Just cheap performance mods.

 

is that MILES per gallon or kilometers?

 

i can def. see that driving that conservativly can get you 28 mpg... i get about 24 highway (65%) city (35%) on premium gas and i try not to drive with a lead foot....

 

that's GOTTA be Kilometers. I just don't think it's possible to get 28 MPG from the 3.4L - unless it's down hill w/ a tail wind BOTH directions!

 

so strong of a wind that hes in neutral the whole time...

 

Is it really possible to control what RPM you drive at with an auto? I can see during acceleration, but wouldn't it just limit your top speed? I'll have to watch where my RPMs are sitting I guess.

so basically he drove through hurricane katrina with the engine off and gearbox in neutral...

 

Maybe he just rebuilt the engine?

 

24??? 28??? is this like a joke lol?? I have NEVER gotten better than 19.1 with two different 4runners.. i average about 17mpg with 50-70% highway driving

 

I think you carried too many 1's over... it should be 18 not 28

I never drive above 2300 RPMs either... I usually get about 13-16 MPG

 

OK
How many gallons did you put into your tank?
And how many miles did you get?
US gallons right?

 

I believe him.

Lifts, and bigger, heavier tires, adversely affect mileage.

I routinely get 22 mpg cruising around town, highway mileage is better. How much better depends on how fast I go. It seems like speeds above 65 mph really start to bring down the mpg.

'97 4Runner, 5 speed, V6, 4x4, Dynomax Ultraflow muffler, my own version of the modded airbox, K&N air filter, NGK Iridium plugs, Mobil 1 synthetic oils in everything, including synthetic grease in the U-joints, slip-joints, and Double-cardon joints.

LT 265/75R16 C Toyo Open Country A/T's. These tires hurt mileage a bit, vs the stock P265/70R16'S, even taking into account the difference in circumference. But the tradeoff is worthwhile to me.

 

I don't believe it. I have a completely stock 123k engine with a new o2 sensor and I can barely hold 14mpg. Now, I believe something is wrong w/ my engine, but getting twice as much?

 

do you guys that get that high mpg live in the boonies or something? No stop and go driving and mostly highway driving?

 

could it have something to do with the elevation?

 

I don't think that that is possible. The best I've ever gotten was 24 and that was on stock tires, with my wife driving. I don't think that 28 is possible unles you have the supercharger and several other mods to help out your gas milage.

 

he did an engine swap for a 3.4 mililiter.

 

It seems a bit high to me, but I am sure it is possible, it all depends on where he is driving. Before I moved I lived right near the highway, so I pretty much got straight on and got off at work, I got decent gas mileage, then I moved and now have about 10-15 minutes of basically coasting in 5th gear around 45 mph and I noticed my gas mileage went way up!

 

my last tank, i grandma'd my way around... about 60% highway, 40% in city... and i got 18.something mpg. thats the best ive gotten in a while.

boston's driving is so erratic.. traffic everywhere, stop signs, lights, rotaries, etc... that i think its tough to keep a steady engine pace.

 

I live and work in the boonies and the best I can sustain is 21-22 mpg, including highway-boonies mix. If that's based on 1 fill-up, I wouldn't believe it. If he gets the same results after about 3 or 4 more fill-ups, well, maybe then I MIGHT believe it.
