Does anyone actually get the posted 22/24 mpg?

I'm clocking in at 17.2 mpg. 700 miles on ODM, I drive like a grandma, I have only put in premium gas, stock wheels, in ECO mode 100% of the time. What gives???? I should be at minimum getting 22 mpg. I wouldn't really care all that much except the tank is tiny...15 gallons. I only get a range of 280 miles per fill.
My mileage is getting better, I’m averaging 22.7 all around. I drive in sport mode around town and normal mode on the freeway.
 
I get reliably 20-24. I commute about 60mi/day mostly freeway but then hills through the city that kills my highway number.

ECO mode. Premium Fuel. Just hit 2,800 miles on the ODO.

Mid-atlantic storm today had be at 20.
 
I have never achieved the posted mpg in ANY vehicle I’ve ever owned, as I learned to drive in NJ/NY metro area where relaxed acceleration was not the norm.
 
15 mpg... had it a week...

Premium??? Regular???

is there a definitive real answer on that yet?

Did you reset the "total average mpg" yet? If not, that average is including a lot of idling time before you got the keys. Reset it.

(Having said that, my latest couple tanks have only been 14-15mpg. Winter + mostly short drives = oof )
 
I’m getting 17 mpg very consistently. I did put slightly larger tires on that are heavier than stock tires and throwing off the odometer (larger circumference).
We just take my wife’s Outback for any longer trips. The Subaru can get 36-38 mpg.
The LC was going to be my travel adventure wagon but the range on a tank is only 260 miles so its mostly going to be the grocery store/hardware store wagon.
 
I dunno how much difference it makes... but I also had the Falken Wildpeak tires installed... not sure how much larger/heavier they are than the stock Street Tires... but for this vehicle, it is a Must Have!!
I expect these tires don't have a favorable impact on MPG.
 
I wonder if much of the disappointment is caused by the reading from the instrument cluster gauge for average fuel economy. There is something funny going on the way it works. The typical formula for what most people consider an average is the sum total of the measurement divided by the count (1+1=2 divided by 2 which equals an average of 1)

Toyota says that it calculates the average continuously but doesn't say specifically how often. Clearly this is a running average based on when it was reset. Even so, I have let it run for several hundred miles and the average dips a lot down into the 15mpg range temporarily and then pops back up to about 20-21. That would be impossible if the count was maintained as a few bad readings would not swing it down that quickly. So I suspect it is calculating the current average fuel economy.

Either way, the gauge is so erratic I would not recommend using it to judge your overall fuel economy. For that you will need to do it by the tank, trip, or keep a nice log like No15 if you want reliable estimates.

I've noticed this as well, at the end of a tank the reported trip mpg can still change surprisingly quickly.

Just finished a 600 mile round trip, mostly Highway, but about 20%, 2 lane county roads. 800 total miles on the car. Been using 91 octane, averaging 25.8 mpg. I do use the adaptive cruise control as much as possible though, I would bet that helps.

How many miles are on your LC?

Average MPG of two trips would not be a simple average of two numbers (i.e (a+b)/2). If you drive 20 mile and get at 30 MPG and drive another 20 miles at 10 MPG. Average fuel economy for the entire 40 mile trip would be 15 MPG as opposed to the simple average of 20.

Same here...driving like a go cart or like grandma.
 
I usually check this out twice daily, after each leg of my 60mi round trip commute.

This is about average. When the heat is on (from what I can tell) it keeps the engine running and stops it from going battery-only… which hampers the range by 5-7 mpg.

7k miles now, averaging 18-19mpg currently. Running Non-Ethanol 91 octane fuel. TBF though, it's winter time too.
 
Welcome to the asylum MikeC.
Average MPG of two trips would not be a simple average of two numbers (i.e (a+b)/2). If you drive 20 mile and get at 30 MPG and drive another 20 miles at 10 MPG. Average fuel economy for the entire 40 mile trip would be 15 MPG as opposed to the simple average of 20.
For anyone scratching their heads:
40m ÷ ((20m ÷ 30mpg) + (20m ÷ 10mpg)) =15mpg
40 ÷ (0.66... + 2)
40 ÷ 2.66...
=15.00
 
6000 miles in. Think we all go down this rabbit hole when we first purchase a vehicle and then eventually just move on. As mentioned by many, no vehicle ever gets the EPA estimates. Think they run those tests downhill with a stiff breeze behind it. I moved to the 275/70/R18 Nitto Terra Grappler G3's. Only slightly heavier than the stock tires. I'm averaging 21.9, which I'm perfectly fine with. As you go with heavier tires, add racks, etc, it will impact mileage. I found that tire pressure made as much as a +-2mpg difference in economy, so that's an important factor too. I settled in at 35PSI and they've been great.

I have the 275 Nitto Terra Grapplers G3's and the standard roof cross bars... and am running at 17.2MPG... after getting my high pressure fuel pump replaced. I'm not overly aggressive in my acceleration and was 21+ before I started having issues... back to the dealer I go
