05 V8 - 22mpg!!!
- Thread starter 05V8SPRT
- Start date
Wow... Lots of feedback....
Let me elaborate a bit more.
I drove VERY easy. I had my 5 yo son and pregnant wife in the Runner. People weight = 195 + 150 (preg wife) + 40 = 385
Rear cargo area had about 250 lb of stuff.
The cargo carrier wieghs about 80 lbs + about 100 lbs on it = 180 lbs
Total weight on vehicle = roughly 850 lbs
GVW = 4500 + 850 + gas = 5500?
Last I checked the tires were at 35 psi.
I run mostly at 65 MPH with cruise. I also checked the computer by dividing the miles by gallons used. It was almost dead on.
I really have nothing to gain by lying. When I first bought the Runner I would only get about 19 MPG highway. I had 5500 miles on her when I left for this trip. Oil was changed at 5K.
I get anywhere from 13 - 16 city. Depending (completely) on how I am driving. If I drive more agressively (WOT starts) then it goes down hill quickly!
I too am VERY impressed by this mileage. About the same as my 02 Highlander V6.

I get 21 with my v8 on the highway cruising at 72. I dont know what all the fuss is about as I really could care less. Its funny how someone says they are getting decent gas mileage and people bash it to death. but would you be happy is someone posted and said they are getting 8 miles to a gallon? I dont get it.

Personally, I wouldn't be happy if someone posted that they get 8 miles to the gallon - however, when someone posts that they get 21 - 24 miles per gallon, the Bhullshe~ote meter starts registering - notice I didn't say the BS meter registers 100% DAYDREAM - rather "Cyclone / Tornado Fuel Saver installed! ". We all know that the indicated reading is different than the manually calculated MPG. So without an unambiguous post, it
I think it's traditional on this board for any claims of V8 mileage above 16mpg to be treated with a high degree of scepticism and a series of detailed calculations - I believe somebody even tracked their miles with a GPS to make sure the calculation was accurate (I presume they measured the gas into the tank with a pipette also).
Just to add my obligatory note of disbelief, I reckon anyone getting more than 20 mpg (US Gallons) must live in a part of the country where the wind is always behind you and all of the hills have only down slopes (or people get out and push the truck up the hills).

Around town and some freeway driving and I get a steady 14mpg indicated.
I am curious though, when I drive the long straight stretch to Mammoth, what is the best speed to set the cruise control at?
I prefer to drive around 75 mph. Should I look to see if the revs are lowest on the tac or is there some other more useful formula to use.
OMG, I am now a senior member. I am truly honored.

I seem to get the best mpg at around 65-70 on the long haul. Driving up to mammoth won't yield you much since it's all relatively uphill on the way up from LA. coming back down is another story so you should be able to yet around 17-18 mpg (v8 of course).
Personally speaking, I'd be pretty excitied if I ever see anything above 15.0 (based off that f'd up mpg calculator too!)
So, damn all of you guys that get more than that! :bash: :bash:

No tail wind, and lots of hills in my area, small mountains. bangin round town, hauling quads and such, sure, gas goes downhill. on highway, steady cruising, she gets good gas mileage. I of course do not verify to the ounce how much was burned or what not, I simply do the gallons per fill per registered miles. I am not that crazy bought it, usually I check it once or twice here and there then as the years go by, the heck with it.
I can say that my wifes runner must of got the hot ECU as hers just rips compared to mine. shifts harder, holds gears better, and just pulls better. Seems weird, they exact same runner cept for paint. I did break mine in prolly different and the ECU must of remember it, I usually have a dog or baby in the car, so I do not hammer the throttle, so its a more user friendly but more mundane car to drive.
I think I will go disconnect the battery overnight.

To put things into perspective for the wacko's:
My 2003 Ford EXPEDITION (aka Explanation) wieghed in at 5700 lbs. It also had a 5.4 V8 versus our 4.7...
I got 19 MPG on the highway wieghing 1200 lbs MORE that the Runner AND a larger Engine... Explain that!
Only a 2 MPG difference with 1200 more in wieght AND a larger displacement engine.... Going by some of the logic in this thread the Expedition should have gotten about 3 MPG...
Many factor involved in MPG:
1. Weather (temp, pressure)
2. Altitude
3. Tire pressure
4. most of all DRIVER habits
5. Engine differences that naturally occur from the factory (not all engines are the same)
6. Poor break-in
7. Octane
8. Fuel TYPE
9. Computer (intelligent & addapts to driving habits)
10. Area you live (mountainous, flat?)
So yes it is QUITE possible for one guy to struggle to get 16 highway and another to get 21-22....
Some of you guys need to go back and take a look at your basic math books and review VARIABLES! The above mentioned 10 factors are VARIABLES in equating your average Miles PER Gallon. There are probably more variables involved, most of which are difficult to derive, and really dont matter all that much...

Road Trip
OK, for what it's worth (especially to the original poster), this week I drove my 4Runner on a business trip to Lexington, KY. Just me and a co-worker and I ran the AC the whole way. Today I filled up (had to since the light came on!) and calculated my mileage from the return trip: 429 miles/19.9 gals = 21.56 MPG. I used 89 octane gas and had my tires at 35 psi.. Now - I will admit that I am a VERY conservative driver, averaging 55 - 60 MPH without any lead-foot accelerations. The trip computer read 23.5 MPG. I have never been impressed with this gizmo (except for outside temperature readings).
My normal driving consists of approximately 80% highway/20% city in which I usually average about 18.5 - 19.0 using 87 octane and 19 - 19.5 using 89 - 91 octane. I would "estimate" my city driving at approximately 16 MPG, although I don't have enough data.
So it IS possible to get decent gas mileage. Maybe if I had the six I would be getting 2 MPG higher!
Tomorrow we are picking up a Chalet Arrowhead a-frame RV. This is a hardsided, foldable camper. We hope to take our first trip with it within the coming weeks and I am anxious so see what my mileage drop will be.

I have 5k miles on my '05 V8 SR5.
My computer is off by about 2 mpg. I thought I was getting 20+ MPG but because I was still a little skeptical I began to log gallons and miles. I calc the real mpg and write it on each receipt after I get it. I have now tracked 5 receipts (all are 20+ gallon fill ups) and they range from 17.8 MPG to 19 MPG. My computer has consistently read over 20 MPG.

Bill42,
One important factor in fuel economy is air resistance (drag). Drag increases with the velocity squared. So there is four times the drag due to air resistance at 80mph as there is at 40mph. Looking at the shape of the 4Runner I would guess that it has a pretty high coefficient of drag, so air resistance would be more of a factor with it than it would be with a Porsche. As an experiment, try driving for a 100 miles at 55mph and compare that fuel mileage to the mileage when running at, say, 75mph. You should see a big difference. I guess 65mph would be a good compromise if the mileage is important.
