Real World MPG with 5th Gen?

the 4G's MPG computer is notoriously "optimistic" however...

ya, that may be the case, i've never actually did the calculations on either vehicle and i'm not that worried about mpg. i do mostly highway driving, but it's typically at higher speeds, 75-80+.
 
Hrmm...after reading the MPG reports from members, I am kinda questioning my MPG computer. I have a 2010 4x4 SR5 V6 and it consistently reads 19-20mpg in the city and 24-27 HWY. Even with aggressive driving the HWY never drops below 23. Next time I fill up I guess I'll get the pen/paper out.

In comparison the 2008 V6 Sport 4x4 is getting around 16City/20HWY and the 2004 V6 SR5 4x4 is getting about the same.
 
16.5 - 17.0 city; ~19-20 highway; calculated by hand. Trip meter matches hand calculation within 0.5 mpg. Tons of sitting at red lights in this city - the combination of sitting there & having to constantly start kills it. I keep the eco light on once i get above 40 or so; can't drive slow enough to keep it on below that.
 
I don't own a 5th Gen T4R yet, but we are contemplating buying one. So we rented one from a local Toy dealer for a weekend recently, and drove up and down the hills through the mountains to a small city in the mountains, then out to a very remote property over very bad roads, 60 miles round trip back to the small city. Then we drove all around the small city, then back up and down the mountains back to the metro area we live in.

This was a 2WD SR5 with about 1800 miles on it. I zeroed the onboard computer at the start of the weekend trip, and we averaged 21.5 mpg over the varied driving of the weekend. I was pretty impressed, considering the vehicle had so few miles on it. I presume the vehicle would get better mileage with more miles on it. Our current driver is an '04 Toyota Highlander. It is lighter and smaller than the 5th Gen T4R, and it would not have gotten any better mileage.
 
How do you reset the MPG computer on the 5th Gen? My Crew Max is pretty easy to do but this seems different.

Push the button next to the odometer a few times and toggle to the avg mpg display, once there hold down the button for a few seconds and it should reset. it's also explained your owner manual.
 
Thanks all. I figure if I get in the 2010 what I'm getting now then its all good. I had a Rubicon Unlimited a few years back and got 16 regardless. One more positive check mark for the Trail Edition. :)
 
I've been b/w 20.4 and 21.4 for the last 20 fill-ups or so. Very consistent. Most miles are at 65mph or so with about 36.9% city driving.

Thanks, got my TE about 4 weeks ago drove it for 2 weeks and have been surfing in Hawaii ever since. I return on the 30th then leave the next day for Yuma Az to dove hunt. Depending on how much room I need, I may drive the TE and check the highway mileage or the Crew Max which gets 19 mph with the 5.7 SC'ed motor or my TE which has shown only 17 mpg combined city and freeway action.
 
I commute 180 miles a day (got my TE in Feb) and have been averaging 21mpg. Just passed 20,000 mile!


WoW that is a serious commute. So how is the comfort level for you? My wife has a 325 that we normally travel in, but with the size and not horrible hwy mpg we may have to switch to the 5th gen when we get it....

I'm seeing about the same thing. Drove to Tampa and back today...220 miles total. The computer says 21.4mph. I've been checking the total mph with a hard calculation at each fill up and the computer has been right on the money. I reset it at every fill up.

This weekend, I pulled the flats boat and associated gear the river. The computer settled on 17.5 mph. I consider that pretty good for pulling 3,800 lbs. and hauling four adults (well...two adults and two high-school humanoids)plus gear.

My Titan averaged 14.5 without the boat...blended with a lot of highway miles. i was getting "thank you" letters from OPEC.

So, I'm definately a happy camper.
 
What about with bigger tires and roof racks?

Reviving this thread to see others' MPGs who have done tire and roof rack mods. With FT4x4, heavier and bigger 275/70/17 BFG E-rated tires on SR5 rims, and Baja rack, I am suffering far more than I had hoped. Also, I have noticed that the AC (and blower fan) consume nearly 1MPG. Getting 15-16 in town, and only 18 on HWY. Over 60 mph, it gets uglier. Also, wondering if the increase in tire size has caused my MPG readout to run lower than reality. Even when I was all stock before my mods, I still could never top 20mpg on an average basis, unless I was going around 60mph on flat roads only.

I did do a 15-mile jeep trail in steep mountain gorges recently all in 4LO and got 13MPGs somehow.

Well, you will have to calculate the difference in circumference of your new tires versus your old ones... and calculating on pen and paper is your best bet versus the onboard one. Basically, you are traveling more than 1 mile for every time your car clicks off 1 mile on the odometer. You are traveling an extra 80 ft for each mile that clicks off on the odometer if you have 285/70-17 tires. So, multiply whatever your odometer reads by 1.035 when you fill up and that is the actual number of miles you traveled on that tank. Use that number for your mpg calculation.

Here is my totally stock 4Runner for the past 4000 miles.

Q,

Nice chart! I like this. While I understand why it is, could you tell me how you got 80ft for the 285/70s and the 1.035 number? Also, mine are 275/70s, so I assume are only a tiny bit bigger than stock...probably 1/2-in taller (guessing) when inflated to 43psi. I have not done math like this since college! Sure would be nice to get a chart on here showing such calcs for various diameter tires for people to use. Actually one with actual tire diameter intervals in 1/4 inches would be sweet!

On a side note, it seems like everybody who is doing his/her own MPG calcs is getting higher values...is this indicating inaccuracy of the onboard calc?

I use the on board and also calculate each time. The on board computer is pretty close, if you rerset it every time you fill up. I'm getting between 19.5 (when in town) and a little over 21 (when traveling).

At highway speeds, it creeps over 22 and has hit the low 23s and then comes down in town. It's cumulative.

The worst I've ever seem was 17.1. That was pulling my boat (also with four grown people, coolers with ice, food and beverages, and a boat full of gear and gas) . I'll take that any day.

My on board computer shows that I average between 15-16 mpg's, mind you I now have larger tires and have had a roof rack for some time. I haven't bothered actually calculating mpg's with the tire difference.

When I had stock size Firestone M/T's I was averaging the same mpg's as well.

Daily driving is pretty much stop and go both in the city and hwy. Work is 8 miles away. I also have a ScanGuageII but never bother hitting the refill button so whatever that shows is wrong as well.
 
Not sure if I got a dud or my car isn't broken in enough yet. I've got a 2011 sr5 4wd and the highest my meter has gotten is 16.8 mpg. Ive done mixed driving city and highway. Always in 2wd and haven't carried much at all in the car. I haven't seen anyone with numbers really lower than mine. ive got about 500 miles so far. :(
