Horrible Gas Mileage

I reset my mileage counter the other day and today it was reading 22.5L/100KM. That's 10.5MPG! WTF? It's -18c out (0.5 F) and at best the truck is run for 3 minutes before driving. I don't remember the numbers on my 2010 TE, but if it was ever as bad as this, I think I would have remembered. Tire pressure has been checked and is good. If I reset the counter when the truck is warmed up, I seem to get more reasonable numbers as long as I'm moving. But any idling (stop and go) and driving the truck when it's not absolutely %100 warmed up and it just absolutely sucks the gas. This can't be right. I'm even driving and trying to keep the eco light on.. I'm not heavy footed at all.

Well the truck goes in tomorrow for a bunch of stuff not working do a command start install. I'm going to add this to the list of my complaints. The truck is absolutely stock, there is no way it should be getting mileage that bad in city driving. I'm not getting even close to what you guys are getting.

let it time to settle. Do some mileage, highway, wait at least a week.

It will probably settle down at around 13-15L/100km at those kind of temperatures.

Unfortunately most of my current driving is city which is where it has to count. The initial range on a full tank shows 470km, but after driving just 80KM the range is now down to 330KM.

The last tank of gas, I got 320kms with 1/8th tank left. I'm tracking my mileage and will fill up when I hit 200 or 300kms exactly. Then it's a simple division of how much gas goes back in divided by 2 or 3 to get an accurate number.

I realize it's all subjective, especially since I am only just starting to pull in manually calculated numbers. My '13 TE combined average MPG computer readout is showing 20.0 MPG, never reset since day one (literally 2 miles on the odo) and currently sitting around 1900 miles.

I tend to baby it and my driving routine follows a 20 mile commute to work in mixed, rather hilly roads. Some points are up and down steep grades and sharp turns, others are on a relatively straight and flat 2-lane highway @40-45 MPH.

On weekends I typically visit family about 60 miles away and am cruising anywhere between 65 and 80 MPH on hilly interstates and notice my cumulative MPG readout always starts dropping. I think that is due to the high weight and wind resistance of our trucks - they are bricks on wheels.

I definitely notice our trucks do a lot better at lower speeds between 40 and 55 MPH. Overall I think this is a good, average MPG for vehicles of this weight and design.
 
Hello Rob, I am having the same issue as you do with my 2011 TE.
19L or 12.4MPG. Truck has almost 12 000 KM on it.

I am thinking of bringing it to the dealer and make them do some tests or whatever they do but I am scarred they will just say nothing is wrong.

Should I go to another Toyota dealer and not the one where I bought the
truck ? I am having issues with quality service ( I don't trust them lol )

But overall I am happy with the truck especially since the big snowstorm that hit Montreal :) I didn't have to take out the shovel to park it anywhere. So that's that.

I know we didn't buy theses truck for fuel economy but I am still perplex with the range people are posting regarding the MPG.

The dealership checked it out, ran it on the highway with a computer connected and said the mileage was good. I think under very cold conditions this truck uses A LOT of fuel when warming up, even more while driving. Therefore I think in some ways it's better to leave it warm up 5 minutes if it's -20c rather than just 1 or 2 minutes and then driving. Or even better yet, plug it in which I haven't been doing, but will start now. Also, there's a shift point at about 55KPH so try to drive just above that shift point if you can. Driving below the shift point seems to have an impact on mileage too.

Today it was -10c and when the truck was warmed up, I reset the mileage counter again. I drove for a while today (30km?), all city and managed to get the mileage down to 13.7L/100KM when I pulled into the driveway.

2012 TE w/ now 750 miles on it

Just got my 2012 TE I commute about 70 miles a day all highway and expected around 18mpg first day I reset trip and went based off computer and switched it to the economy setting where it shows how much fuel your using its made me realize how much gas I was always wasting I used to be a crazy driver but keeping it in that range using cruise control on the way to work I've been getting 22mpg bone stock for 3 straight days I was more than happy and then I mixed in alot of around town driving giving my friends rides in my new 4runner them put on my new Thule snowboard rack and the computer said avg mpg 19.2 I calculated what it actually was and it was 19.4 and that's half the miles with the new rack and in town I am more than happy with my new 4runner no buyers remorse at all but I do plan on getting some intake maybe afe airaid or Trd CAI once I put 285 70 17s on it but it already has some good size 265 70 17s ill be interested to see what happens when the motor breaks in and I add a 3" lift to it in a few months

When a car is idling, it is getting 0 mpg. More idling will never improve your overall MPG. The best thing is to start the engine, and as soon as it's running smoothly, (usually only seconds, unless something is out of spec) drive away taking it easy on the acceleration. The vehicle will reach operating temp. much quicker, while being driven.

Cold weather is bad for getting good MPG for many reasons. The engine will run richer (burn more fuel) until it reaches operating temp. All of the oil in the drivetrain, and grease in the driveshafts, is more viscous (thicker) when cold. So there is more drag to overcome when the vehicle is cold, which also hurts fuel economy.

There is usually more demand on the electrical system too; HVAC fan running, defroster on, headlights often on, maybe seat heaters, etc. All of this places more load on the electrical system, which means more load on the Alternator. Turning that heavily-in-demand alternator places more load on the engine, which burns more fuel to compensate for the additional drive load. If the HVAC defroster is on, then the A/C compressor will be engaged to help de-humidify the interior. That also places more demand on the engine, which in turn burns more fuel.

On the bright side, May (with it's warmer temps) isn't that far away.
 
Does a lift and using 285's reduce the accuracy of the computer?

What is the aspect ratio of the tire? If the diameter of the tire increased, for every mile you drove per the odometer, the vehicle actually went further. Your fuel economy will appear to be worse than it really was. A lift will not impact accuracy; it will impact your mileage, though.
 
Just turned 10K. Initial Mileage around 17.5 overall. After a few thou and now, around 18.5, 50/50 mix and 23 hwy @ 75-80. I'm a fairly aggressive street driver and don't consider that mileage too bad. Haven't done as much off road as I'd intended or would like to do. More in 2013.

2012 Salsa Red TE with Duratrac 265 C all around on Koenig 17s.

23 MPG highway... at 80MPH? Is your truck running on some kind of nuclear fuel!

OK, so I was blowing down CA 395 (it's downhill going south) and farting around in the Eastern Sierras, average elevation on 395 around 5000 ft with less wind resistance but at least three sides over 9,000 and no, I wasn't going 80 on the sides, but most of the actual mileage was on CA 395. I know, I know, also less oxygen, but I do the calc every time I fill up. So maybe it wasn't all at 75-80, but it mostly was and that's what they do on 395. This was about the only time I've done highway only (mostly), so take it for what it's worth. Similar mileage going over the hill from LV to Central California and from Lone Pine through Death Valley back to LV, but I don't remember exactly what those were.
 
With just over 3,000 miles, my beauty '13 TE has averaged 19.82 mpg. I got one tank that averaged 23.24 mpg on run from Durango to Albuquerque (mostly down hill and cruise control).

I have iPhone app called Car Minder that figures mpg to .00 and also reminds me of service when miles come up (a very excellent feature for an old man).
 
I got 19.8mpg on my last tank that was pretty much exclusively driven in slushy, nasty snow with a large portion in 4WD. It was all highway at 25 to 60 mph, though.

100% stock other than Husky mud guards and some aftermarket floormats.

This is a thread I will link to in my "top ten" questions.
 
I never owned a vehicle that had such poor winter fuel economy. The truck uses %40 more fuel to warm up at -18c (0F). At -34c, it uses %75 more. This is city driving. When it's fully warmed up, then it gets respectable. But for 20 minute drives to work, the fuel economy can be bad.

Since picking up '13 SR5

70% highway at 75 mph
 
I get a horrible 14-16 mpg, city driving here in Honolulu, HI. Stop and go between lights, crap drivers (braking accelerating defensive), and hardly any freeway driving. On rare freeway drives, mileage will go up to around 18-20mpg. On the bright side, work is only a few miles away so I fill up every 2-3 weeks.
 
It's interesting to read through this thread. A friend of mine with his newly purchased 2013 JGC has sent me pics of him getting 530miles on a tank numerous times. He's no the lying type so I'm inclined to believe him regardless of how outrageous that seems to me. Roughly 23mpg, I suppose.

For the 4runner being rated as having the same to 1mpg less than the JGC, it's surprising how many are getting 17-19mpg. That being said, those numbers seem far more realistic.
 
A lot just depends on one's driving conditions and style. I have consistently been getting between 21.5 to 22 mpg along the front range about 40/60 city/hwy.
