I've seen multiple comments on this thread stating that cooler weather causes worse fuel economy whereas warmer weather increases the fuel economy. I live in Phoenix Arizona area and I find that to be completely the opposite statement at least right now during summer. The obvious factor is running the air conditioning all the time. I have a 2016 and the only modification I have done to it is I've added 275/70/17 BFG KO2s. Yes those tires will cut fuel economy. But my truck gets horrible fuel economy . I'm getting approximately 15.5 to 16mpg with mostly city driving. Anyone else in a similar climate with similar tires experiencing these same results? I'm guessing it's normal as with every other irritating thing I've noticed with my truck. I keep trying to rationalize/justify it by saying to myself "man it looks good". The money factor on the fuel economy is not really an issue it's just more of an annoyance...
 
New owner here, looking forward to seeing what sort of mileage I get with my TRD Pro. I drive fairly conservatively and generally obtained between 21 and 22 mpg with my 2012 FJ Cruiser doing a mix of city/highway driving. Best I saw in the FJ was just over 24 mpg.

Still on the first tank of gas, with only 115 miles on the 4R, so the only thing I have to go on is the computer at this point. It has been showing between 18 and 19.5 mpg so far. Hoping once it gets broken in that it will do a bit better.
 
i used to track the mileage on my 4runner but ever since i got my lx470, i'm no longer concerned...lol. and like others, my wife also gets about 1-2mpg less when she's driving.
 
Guess I've been faking my numbers and lying about it for 7 years. I still contend that my onboard computer is more accurate than hand calculations tank to tank due to fuel pump variances.
Oh, one more thing...in my experience, driving with the trans in S5 makes no noticeable difference to mileage vs. keeping it in D.

Well, defiantly didn't want to put it like that. :) I totally buy you getting 21.9 mpg, because that year/model of 4runner is rated at 22 mpg so I can buy that, the latest ones are only 20mpg. Some guy above posted 26+ mpg? Really, please that simply can't be right, well I suppose if you drove tailwind on the highway you might get that, once, but overall I still don't buy it.

Am I missing something here, most auto techs will agree that you will almost never see better than sticker mpg in any vehicle, mostly you will never see it period.

Finally, if the gas station fuel pumps are all off, then this whole thread is pointless.

Hey now... my old IH Scout II got 31 MPG...





...with a tail wind...


...downhill...


...being pulled by another vehicle.




...it might have been leaking fuel.

Aren't they the same motors? I thought the lower MPG rating was from tighter EPA guidelines.
I generally agree that anything above about 23mpg for me is a result of better than average conditions: a tailwind, less than 70mph, useful elevation changes.
I'm sorry, I mean gas station pump shutoffs tend to be inaccurate.
 
According to fuelly app i'm averaging 18.6 MPG over the first 10K miles. That being said I don't drive gently, and highway speeds average 70+ MPH.
 
Got my best tank the other day.

Background on this particular run.
I was traveling between Durango and Albuquerque via Hwy 550. I was tailing our RV with an average speed around 55-60 mph. (There were a few construction zones that slowed us down.) Temps were 100+ when we left Moab so I had the AC running. I was using 88 octane fuel. (Low grade fuel at home is 87 and I didn't want to use the 85-86 I was seeing out west.) I have no idea what pressure my tires are set at but, they are stock size Falken AT3Ws in p load range. I have leveling spacers and was loaded with luggage.

I average around 18.5. Typically that's mixed driving through rolling hills. I sure that number would be over 19 if I didn't tow so much during hunting season.

I just filled up again yesterday, I had a bit of highway miles on this fill up, maybe 20% of the tank highway miles, and I got 16.6 mpg on this tank, best I've gotten so far, but only filled up 4 times so far since I got this thing.
 
15.5 mpg ( US ) city/most trips <4 miles including 6 traffic lights...
17.4 mpg ( US ) hwy/mountain
saw ~20mpg ( US ) on extended hwy trip last summer
 
I just crossed the 2K mile mark and am averaging 22.3 mpg. During the week my commute is 80% backroads and 20% city. Weekends is really around town only.
 
After a now full year of ownership of my new-to-me 2011 Limited, I found some interesting seasonal variations in my average fuel consumption (mainly city driving):

Spring = 16.6 mpg
Summer = 20 mpg
Fall = 18.4 mpg
Winter = 15.4 mpg

All figures hand calculated. Lower mpg in winter and spring are likely impacted by the winter gas formulation.
 
I've found if I conciously try to increase mileage I can get around 22, but it's aggravating. I'll just have to live with the 15.7 I'm getting now lol. Seems like there is a wild differnece in mpg between my normal and conservative driving, but I might not have noticed it in my previous vehicle.
 
In SoCal: No, and no.

I'm not 100% sure about the Central Valley, where the blends may differ. There may be a useful real-world mileage difference between 87-octane gas that is 10% ethanol and 91-octane that is ethanol-free, but I doubt it's enough to offset the cost difference.

Possible ethanol content issues aside, there is no point in using premium gas in a T4R.

Agreed. I live in Los Angeles. There is no point in using premium gas in the T4R.

You'll never make up the money spent on 91 octane via increase in performance/fuel economy - real or perceived.
 
With my 3" lift and heavy Toyo RT's I'm getting about 17.5-18 mpg on the highway at around 75 mph.

Around town during the week with lots of stop and go and never getting above 45 mph I'm averaging around 14 mpg.
