V-6 MPG Post up!

[Boaz]

I checked my MPG today and it was a whole 16.5 mpg. Mostly highway, some city driving. I want to compare to your alls average MPG. post up please!

 

[tkr128]

I've only managed to get slightly over 24 a few times so I put in mine for 22-24.

Current Mileage: 31,000
Fuel: 91 premium
Oil: M1 Synthetic 5W-30
Tire PSI: 32
Driving Style: Relatively conservative with occasional "outbursts" when somebody pisses me off. I'm usually driving around 60-70mph
Driving: 95% highway with my commute being 100 miles round trip.
Last 3 fill ups: 23.06, 24.63, 22.65

Here are my findings: My mileage increased a bit after 20,000 miles. You get the best mileage driving at 50-55 mph and mileage decreases rapidly past 70mph. The bug deflector helped the mileage slightly.

EDIT: I edited to include some more info about the way I drive.

Since I bought my 4runner in Dec, I'm averaging 19-21mpg. I do mostly 85% hwy driving(I average 2500-3000 miles a month). I've also noticed that if I use regular grade, my mpg drop about 1-2 mpg. I stay with premium and with the better gas mileage, I end up paying half of the difference in cost. Cruising at 70mph also makes a big difference.

 

[irwinSR5]

why is it that some people get 24mpg and others (like me) get around 16.5?

I realize that the way you drive as well as the speeds (roads) you are driving on make a difference, but 7.5 mpg difference?!

'04 V6 Ltd 4x4 (mpg specs are for 2wd mode, I only put it in 4HI in bad weather)

Driving style: 75% aggressive; 25% moderate
Average highway speed: 80-90mph
Fuel: premium 91
Oil: synthetic (M1)
Daily commute: 95% highway, 5% city (usually 150miles to 250miles daily; 3,500 to 4000 miles monthly).

here's several scenarios/setups that I've encountered:

1) stock from dealer (dunlops @ 32psi): 20-20.5mpg
2) stock from dealer (tires @ 40psi front; 38psi rear): 21mpg
3) addition of Yakima Megawarrior basket w/extensions (tires @ 32psi): 16mpg (way too much drag, especially at higher speeds)
4) addition of Sunroof Wind Deflector (improves aerodynamics & noise levels of the installed Megawarrior basket) tires @ 32psi: 17.5mpg
5) addition of sunroof wind deflector (same as #4, but tires @ 40psi front & 38psi rear): I will soon find out after several fill up

my current configuration is #5

all mpg figures are hand calculated, display readout is usually 1.5-2mpg higher. I usually refill the tank when there's 1/4 to 1/8 of a tank remaining.

future setup #6) add on the front hood protector/deflector, may improve aerodynamics a bit

 

[2K34R]

In the city, my best doing 50 -55mph, and not rev over 2k rpm I have gotten 18.4 mpg

Revving over 2k rpm and driving about 60, 16.4 - 17.8 mpg

On the highway, my best milage is always holding steady at 70 mph.

 

[Hitman]

I average about 18 miles per gallon, but that's with about 75% stop-and-go driving on backroads.

On a long highway trip, I average about 22 miles per gallon. I could probably bring that up a little, but I tend to mash the pedal once in a while

Well, I'll tell you one thing for sure-- all these people that changed their tire size to 265/70-17 do not get accurate mileage figures because their tires are 1 inch taller than stock.

That's enough to make a fairly significant difference in mileage figures....

 

[4RunningGuy]

I have about 2500 miles and use 91 octane and only get about 17 miles to the gallon. I do both highway and city driving and I'm pretty easy on the pedal. But I think the thing that affects my mpg the most is I usually warm up my 4runner for 5 minutes.

so would that make the milage "appear" on paper better or worse? I just cant understand why there is such a gap in our mileage. I will play with tire pressure to see if that does anything.

I just ran some injector cleaner through as well as a take of premium. I only have 18,500 on the clock , so maybe Im starting to get her broke in ..... i dunno, i just expected a little better mileage.

 

[4RNR4BB]

I usually get between 15 and 16, mostly around town driving. On the road trip from San Diego to Reno, I averaged about 23 MPG.

Why are you guys filling up with 91 octane?

20 mpg here always (mixed driving). Interesting observation though: lack of fifth gear means drop in gas milage at speeds over 75 mph, bomer...

I didnt think about that, all 2004 V6's have the 4 speed auto right?

 

[Hitman]

The stock tires (265/65-17) do 660 revolutions per mile (circumference is 96 inches)

The tires that a lot of people here are running (265/70-17) do 638 revolutions per mile (circumference is 99.3 inches)

This will make the speedometer/odometer 3.4% too slow, due to the larger tires.

If a full tank of gas lasts for, say 300 miles, the difference in revolutions between these two tires sizes is 6,600 for just that one tank of gas !!

All city and Autobahn

Right at 17.

Best was on a recent trip averaging about 90 - 95 mph and I got 21.7 there, through the mountains.

When I was still in the states I got 24 on a trip averaging about 70 from Cocoa Beach Florida to Louisiana, it was about 2100 miles round trip.

I'm adding the Gen 2 FIPK and every time I've had it on a vehicle before it has added at least 1mpg in the city and 2-3 on the highway trips, can't wait to add it

I get about 25 on the highway at 65 mph with my '90's 3VZE and 5 speed running 235/75R15's (instead of the stock 225's).

I have a K&N drop in filter, changed all my fluids recently (yeah, over 3 gallons of gear lube!!!) and keep 45psi in the tires. Lund claims their sunvisors create better airflow, maybe that is the secret:lmao:

Now, this is based on a 40 mile commute on a 4 lane highway at 65mph and figuring mileage based on odometer and fillup figures.

In town, I get about 15ish.

If I kick it up to 70 I still get about the same, but it drops off steeply at 80. Over 80 is unwise and unsafe on our roads.

Combined totals, my wife averages about 15 to 20mpg as she drives solely in town. I get 25ish as I drive solely highway.

The weird thing is I have the full time hubs, not manual hubs. But even the guy I bought it from was amazed at the mileage they got with it. His previous T4R got about 20 on the highway. I guess I just have one of those fluke vehicles you see from time to time.

Now watch, when I rebuild the engine, I'll loose all semblance of mileage and it will treat me like my old 77 Suburban did: 5mpg!

 

[MicaBlue03]

I usually get a little over 16 MPG in driving that's around town, some hills, and sometimes a load of passengers.

When my commute was 25 miles round trip with light traffic and only a few hills I got around 20 MPg.

Cruising around at 65 MPH on relatively flat highways with infrequent stops I could approach 25 MPG, but it wouldn't take many hills or a headwind or very many stops to drop this significantly.

The 4Runner is not a light vehicle and not very aerodynamic, so it's easy for factors such as speed or hills or stops/starts to combine to make a big difference in mileage.

That's correct, with Overdrive but I don't think its enough for good gas milage at illegal speeds. That must be the reason 2005 got 5-spd.

 

[sharp4runr]

I get about 17-18mpg per gallon normally. Since its been cold and snowing the recently, I've warmed up the truck longer and drive in 4WD so I've event gotten as low as 15mpg.

These are the stock dunlops at about 35psi (last time i checked)

 

[TechWrench]

20 mpg here always (mixed driving). Interesting observation though: lack of fifth gear means drop in gas milage at speeds over 75 mph, bomer...

I believe the final gear ratio is the same for both the 4 spd and the 5 spd, so at highway speed there should be no transmission gain or loss between them.
