Real World MPG with 5th Gen?

I have a 1.5 mile city commute to work and back to home everyday. I am only driving about 5,000 miles per year with the rest of my weekend around towns and outings.....15.6 mpg average

I am on my 4th tank, 1st 2 read 18 and change on the computer. 3rd tank read 19.7 on the CPU but calculating it I was at 20.02.
 
16.3 mpg mixed driving in windy area. I have full Gobi stealth/ladder/led bar, which adds decent weight to the truck (~180 lbs). I drive 75-80 mph freeway, and hard on the gas after stop lights.
 
I am getting 15.6 mpg, gobi roof rack, ladder, shrockworks back and front bumpers. stock sized bfg ko2. most of the drop happened after the tire change and roof rack install.
 
i notice something weird happen last night. I was sitting in a drive thru and notice my mpg slowly going down.

I just reset the mpg after getting gas 4 miles away. It showed 14.8 and within a min it goes down to 13.6 mpg.

I swore before when I was stopped, it goes up instead. Currently its at 16.9 driving to work (mostly freeway).

Yes your average mpg will drop when you're idling while not moving so it's working normally.
 
i'll chime in as i have close to 6k miles on it since new. am averaging 18.2mpg with 95% city driving, calculated via fill ups. but i don't drive it hard. stock btw.
 
I have just over 40k miles. I average around 20-21 with "city" driving. (If you have ever been to Sneads Ferry, NC you will know what I mean) When I travel pure highway I can get it up to 23 mpg, but I am usually weighed down more.

This made me think on the way home. Its not necessary true...when idling, the a/f should maintain the best possible fuel mixture of stochiometric which is 14.7 to one. When you are on the freeway or cruising the ecu is maintaining stochiometric to maximum fuel economy.

I need to hook up the laptop and see if I can read the a/f what the car is running. That should tell me how my idle a/f is.

When you're not moving you are getting ZERO miles per gallon. Over time (even a short amount) it will cause your average MPG to go down. That's pretty elementary. You're burning fuel and going no where.

that does make sense. Next time when you are out, can you check your car to see if your mpg drop standing still for a minute?

put it on the mpg and see how far it goes down in a minute. I would be curious to see. Thanks

The rate at which it drops will depend on how long its been since you last reset the meter. If you reset the meter 1 min before you stop, it will start dropping almost immediately. If you have been driving for a month since you last hit reset, it may take 1-2 minutes to start dropping.

The meter basically takes a snap shot of your MPG every 15 seconds or so and displays a running average. The more data points you have, the less of an impact sitting still will have. I dont know how many points the data is limited to, but I believe it's several thousand. When the limit is reached, the computer drops the oldest entry and replaces it with the newest.

IIRC, there's a thread on here explaining how it works.

On Topic - My avaerage since new it 18.40 mpg. Highest tank was 21.5 and lowest tank was 12.

1,350 miles in, I have averaged 17.3 MPG. 70% city driving with colder Chicago temperatures. Each tank has gotten better, with last nights fill-up at 18.1 MPG. Expect the upward trend as it breaks in and the temperatures warm up here.
 
This is all stock 2012 SR5 4x4 with running boards and KO2 265/70R17 C-rated. Tires are inflated to 38psi for quite comfortable ride. After that trip I check tires - they we cold.

Here is the first full tank real mpg after switching from Stock Duelers to KO2 (same size, C-rated): 20.354mpg calculated (335.7 miles, 16.493 gal). My driving style did not change. With Duelers I would say the average I got was around 20.5 on the same route. So if there is any drop in fuel economy after switching to KO2 it is minimal. For sure it is worth the improvement in ride comfort.
 
when driving like a sain person, i get 19 hwy and 14-15 city. if i drive normal ill get 14 hwy and 13 city. thats with a 3inch lift and 285/70/17 MTs
 
For the change I decided that for one week I will be driving less "green". It means accelerating at 2-3k rpm and pedal to the meal when I needed power (passing). I did not drive like a maniac or like I stole it, but for sure less "old lady driving" like I'm used to do. I was curious how driving style would affect my average mileage. After one week of driving the same commute and the same speed limit I measured 19.6mpg. That is 0.7mpg less than "green driving". When I change back to to my "old lady" driving style the average went back to 20.3mpg.

The funny thing is that regardless of my driving style my daily commute takes exactly the same time. The only difference of being less "green" is that I used more gas and probably more brakes.
 
My '13 SR5 is mostly stock. The only change to impact economy is stock size tires in an aggressive tread.

I usually get 18.1 mpg but as the weather is warming I'm getting around 19-19.3.
If the weather drops below 50*, my mileage drops to 16.5 - 17. When I was in ND, winter weather netted 12 - 13.5 mpg no matter city or highway.
So, my 4Runner is impacted by weather.
 
This is crazy to read!! I live in Canada and my truck reads at 16.6 l/100 kilometres which equals out to about 14.1 MPG!!!!! WTF!!!!!! That's a mix between highway and city. I know I live in kind of a up and down elevation, but for my mpg to be that low something has got to be wrong? Only mods is are a Rola roof rack with the extension and a 3" lift.

Yeah I don't get it either. When I got my truck, it was reading 13-14 mpg stock. And this was never going over 2500 rpm, driving like a snail. Now I'm lifted with 285/70/17 and still driving like a snail and it's reading 11mpg. People keep telling me this is right, but I call BS.
 
I'm still in the break in period (2016 TE) and just finishing up my second tank. First tank I averaged 11.7 l/100km (20.1 mpg). My second tank I'm getting 10.6 l/100km (22.2 mpg). This is a mix of city and highway, roughly 30 and 70.

For those whose mpg dropped after they lifted, mine did as well on my previous Taco when I put a lift on it. Seems to be the norm.
