Does anyone actually get the posted 22/24 mpg?

MPG…MPG…MPG
Hundreds of conversations, discussions, and endless…
Many reports are not “complete” with all factors such as model, accessory, road condition, driving habit, etc.
Summary are 4 lifestyles, users, purposes. They are all great and provide the satisfaction, happiness:

1/ Maximum MPG 22-26: stock street rated / smallest tire size 245/70 R18, no running board/side step, no skid plates, no roof rack, no built-in drawer system on trunk, no ACC lights, no air compressor, no window open, no passengers , super light gas pedal grandpa style(last one to hit stoplights and last one to leave them)…or even fold the side mirrors while moving
LC intentional purchase: mpg, cool box, but 1980 Honda civic speed

2/ Medium-High MPG 19-22: stock street rated/medium tire size 265/70 R18, no rock rail but running board/side step, roof rail but no cross bars or roof rack, empty trunk, no other ACC stuffs, medium gas pedal/in middle or a bit behind among traffic flow

3/ Medium MPG 16-18: bigger and AT tires (SL-E rated) 275-285/70/R18, rock sides, 3/4 roof rack, minimum ACC lights, drive at normal or a bit fast speed (middle or top of fastest group in traffic flow)

4/ Low MPG 13-16: AT rated E tires 275-295/70 R18 or R17, wider stand for wheel/tire, full roof rack, all ACC lights, built-in air compressor, built-in drawer/fridge/sleeping system in the trunk, rock slide, light/steel integrates front bumper+winch. Full lifted/suspension equipped for all terrain off-road trails. First one to hit the stoplight and first one to leave it. Drive as “real muscle” LC

Which group are you belong to?
All can be happy for what we choose.
I am in group 4 hahaha and have to run fast before rocks thrown on me

Happy LC to all. Happy Holidays

Nailed it!!

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.

I'm getting 23-25 with stock Michelins, and a Yakima rack with wind fairing on top on the highway doing 45-60mph at 3000miles

Someone correct me if I'm wrong, but 5 minutes of idling is just wasting gas unless it's to warm up the cabin. Modern engines need maybe 30 seconds of idle, then gentle driving for a few minutes. This has been a holdover from the carb (and choke) era...

Warming up at 10F and warming up at 60F are not quite the same concept.

Also I found it weird that sometimes I turned on the engine and it only runs for about 30 seconds to shut itself down, while other time it could run for 4-5 minutes until the engine turns off. Is there a sensor somewhere the vehicle used to decide how does it needs to run the engine during idling?

Probably depends on the charge level of hybrid battery as well as cabin temperature. If you idle it at 10F with cabin temp set to 68F, it won’t turn the engine of until set cabin temp is reached.

Additionally, I am sure there is a set value for catalytic converter temperature that the engine will run until it is reached.

Below is from Consumer Reports a month ago. Not that they are the end all, be all, experts, but this mirrors everything I know about why you don't want to let your car idle for extended periods, even at 10F. If you want a toasty cabin, then by all means you'll get there faster by driving it rather than sitting in a parking lot idling. You're not causing wear or damaging your engine by driving after a short warm up and gently driving it. Remote start certainly changes the equation for people.

"When the temperature drops during winter, it’s a good idea to let your car run for about a minute. Some drivers prefer to let the engine idle for 20 minutes or longer to get everything—including the cabin—really warm, but the fastest way to warm up an engine is by driving. Just remember not to rev the engine hard for the first few minutes of driving. Wait until you see the temperature gauge move off the cold reading.
In terms of comfort, when you drive the car it’s going to warm up in just a few minutes vs. idling for 15 or 20 minutes. Extended idling just wastes gas."

Update on my previous post concerning the MPG subject. I removed the cross bars yesterday, what a big positive difference in the wind noise, much quieter and the occasional rapid swirling wind noise at highway speeds is gone.

All day today in ECO mode for my highway commute, between this adjustment and the removal of the cross bars the mpg figured went up to 23.4 in the city-highway, finally saw the 24.4 mpg for the 80 mile freeway portion of the trip.

That sounds exceptional. What kind of sail are you using? I was able to average 21 with the stock Michelins, which I was fine with. Just switched to the Nitto Terra Grappler G3s. Assuming that I'll lose a mile or two, but when I hear the occasional owner quoting 23-25 (haven't seen many), it leads me to believe that tire inflation, weight, driving habits, etc. really seem to make for wide variations in mpg.

Wow. Just doesn't seem like removing the cross bars would create that much of a delta. I could run down hill from Mammoth with the car in neutral and I still wouldn't see anything close to that

It was the second time running all day in ECO mode, between the ECO and the crossbars it made a difference, first time seeing over 23 mpg and then the 40 mile stretch of hwy finally saw over 24 mpg.

The sound difference alone was very impactful, that pulsing whirling noise that would start and stop at highway speeds is gone.

Got it. Possibly a typo above as you were referencing 34mpg. Either way, interesting that removing the crossbars would make a pretty decent difference. Good to know, as I wouldn't always use them.

I quit keeping track of my mileage. I was getting around 17 mpg at the time but now I’m just driving it because I enjoy driving it.

 

[DeepDive]

I actually thought about switching to the view that shows audio in that spot. You do what you can do and at some point after that, it really doesn't matter

First 2500 miles, 50/50 city/hwy driving (highway is mostly interstate 75-80 mph)
22.8 mpg average so far

Tire pressure matters.

After a cold snap, the pressure in the Michelins dropped from 33 psi, to 29 to 30 psi. I drove 103 miles to my daughter’s house and only got 22 mpg.

Two weeks later, I had finally filled the tires back up to 33 psi. I made the exact same trip yesterday, and got 25.6 mpg (LC trip computer both times).

Tires and tire pressure make a big difference in fuel economy. When I swapped OEM tires for a more aggressive (but same size) on-road/off-road tires in my 2018 Highlander, I immediately lost 2 mpg.
Swapping OEM low rolling resistance tires for oversized off-road tires will easily result in 3-4 mpg difference.

Something as simple as pulling away from a stop light, can have significant difference in fuel economy. On my last trip to my daughter’s house, I was using cruise control on the two lane highways, with all the ‘driving nannies’. As traffic would come to a stop at a traffic light, Miss Daisy would slow down, and stop with traffic. Then a small box would appear, to push the accelerator, or ‘resume button’ when I was ready to go again.

By pushing the resume button at the earliest possible time, Miss Daisy would sit there, and SLOWLY start accelerating, with the traffic, back to the 55 mph limit, keeping the safe following distance that was dialed in already. Not a jackrabbit start like most people do, revving high and prolonged engaging of the turbo.
