Real World MPG with 5th Gen?

[TEujunga]

Too much air under the vehicle? Maybe lifted trucks need a front air dam.

I think you are correct. It may be part of the reason for the "factory rake" (lower in the front than the back) you see on T4Rs as well as other SUVs -- manufacturers trying to squeeze out every extra tenth of an MPG.

That and the higher rolling resistance of A/T tires are the culprits for lower MPG in my case, I think.

It's funny because I chose my tires with such care, opting for 275 Load Range C rather than the 285 Load Range Es that so many people run, just so I could minimize the MPG hit. Oh well -- best laid plans, and all that.

My own results so far.



Just a quick ghetto spreadsheet. Been meaning to do it for a build thread that I just haven't quite gotten together yet.

In my eye, the outlier is the first figure, post dealership (302 miles). That was almost all highway driving and a tiny bit off-road (wtf is the point in buying a 4Runner if I don't get her dirty the first weekend?).

I was expecting the Cooper ST Maxx E-rated tires to take a bigger hit. If I had to guess, I'd say about a 1 mpg hit. A lot of my driving is city driving, so a fair number of starts and stops. (edit: tires are 265/70R17)

What I HAVE noticed? Driving like an ******* takes the bigger hit. My worst was when I was driving it aggressively a couple days just to get a feel for her limits. That's the 14.9. My best? Road tripping on Memorial day weekend. Even with some stretches at 80 mph on the freeway, driving it more conservatively bumped it up to 18.1. I honestly think I could have stretched it to 20 easy, had I not tried to keep up with traffic that morning.

If you want to kill your fuel economy, drive fast and go for quick starts/stops.

My company provides me with a rental vehicle and last year I had two different 2016 4Runners each for a month. My commute to work each way is about 104 miles, mostly on a highway with 80 mph speed limit. You can guess how fast I really drove but at that speed for about 220 miles a day, I was getting around 12 mpg.

 

[5280 TRail-Runner]

With a lift, roof rack and 275 e load tires, I get about 17.2 mpg. Most of which is highway driving. I went on a camping trip over the weekend and had 2 kayaks, 4 mountain bikes, 3 other passengers and all the gear which probably totaled closed to an additional 1500 pounds and I got about 15.2 mpg and this was all highway driving in the mountains. I was honestly expecting less but I didn't floor the gas pedal so that probably helped. Moral of the story, drive with a lead foot regardless of what mods you have, your mpg will suffer so ease up and enjoy the ride!

Tire pressure

The dealer set the tires on our '16 4R Trail at 32 psi and we were getting about 19 mpg on short trips in fairly mountainous country. I always ran my previous 4x4s at 35 psi so just upped these. In 2 weeks we'll be heading off across the mountains to visit family in Omak, Wash. and I'll be interested to see if there is any noticeable difference. I'll let you know. - Ted

This comes to mind....... lol

I've only put on 2300 km's since I picked up my 4runner. The first 800kms were all highway, the 1500 since have been 95% city. I am averaging 13.4 L/100k which equals 17.55 MPG.

Thought I would add, I am running the stock 20's and rubber.

 

[Cuse Runner]

I average around 19-20 mpg driving back and forth to work. I get around 420 miles a tank. I haven't tried to get to gas light and passed yet.

14.6 mpg

shrockworks front bumper
8k winch

285/70/17 toyo at's E range

.and my 6'3" 350lbs fat ass

 

[tacoyota]

I average 15.7mpg mixed driving for 2017 TRD Offroad 4x4 on 275 ko2s. My friend who just got the same model hit 24mpg highway on dealer tires! I always thought people posting these outrageous numbers were fishy but now I believe it lol.

How do you reset the MPG reading??

How do you reset the MPG reading??

Unplug your battery for couple hours

 

[DeepSea]

Went from combined 20 to 17 mpg after installing 3" lift and 285s and now 16 after going to 305s

 

[Trixx]

We didn't do any long highway trips prior to doing the 285/70r17 tire installs, but once those were installed we did a 200 mile round trip and hand calculated about 19 mpg averaging around 70-75.

Since then we have added a lift and some other goodies that I feel like have brought it down to maybe 17? highway. We will check it this weekend but we will also be pretty loaded down for camping, so we'll see. If I can get 17ish still on the highway around 70-75 I'll be happy.

I've seen similar MPG with Tacomas with the exact same setups so it must be the way the motors were tuned or something during manufacturing

 

[LandCruiser]

Lifted, Destination MT 285s, steel wheels, sliders I'm averaging about 14.1 per tank (mixed city and highway).

What? Just hold down the display button on the newer models. Hold down the trip odo reset or the reset on the central display when the mpgs are showing on older 5th gens.

 

[greatape]

I'm running slim front bumper/winch and full steel rear plus complete cargo system and other aux items so it's has some weight. Also 3in lift and 285/70/R17s. I was averaging around 15ish but lately getting closer to 16 and that is all relative to driving conditions and elevation. Seems like I may be getting just a slight increase in performance after the snorkel coupled perhaps with a little more positive rake from the front bumper winch..springs settled approx. 1/4in at most

Please report back when you can if you've continued the 91. I don't see how others are getting close to 20, I've been averaging 15.8 for the first 5300 miles. I do pull a small tool trailer during the week but it's not heavy. Monday I put trd wheels and ko2's on mine, still hanging at 15.7 but expect it to drop. Fwiw I have a limited also, maybe it will get better after a few more thousand miles?

In a lot of states, premium gas is except from ethanol requirements. Many times people will think they are getting better mileage because of the higher octane, but in reality, it's because it's oxy free.

 

[Xscream]

I have a '15 TRD Pro that is basically stock. 75/25 freeway to city driving. I've been averaging 20-21.5 per tank in the summer. I typically loose 1-2 MPG in the winter.
