Real-Life MPG Thread - Share Your 2024+ Tacoma 4th Gen's Gas Mileage! ⛽

285/70/17 all terrain tires on my 2025 trd off-road hybrid without the air dam. Diamondback bed cover and no other exterior mods. I’m getting 18 - 19 mpg. Currently at 6,000 miles.

About to drop down to 14-15. Time to add the 180 lbs of sandbags to the bed for winter ;-)

First two tanks both at 24 mpg. But I was in the break-in period.

Are these numbers 4 the 4 bangers ???

Mine is SR5 4x4.

Since a four banger is all you can get, I'm guessing yes. And I'm averaging 27 mpg combined city/hwy with my SR5 2WD.

With temps finally dropping I'm down around 17-20mpg mixed. An observation I've made having not owned a newer Toyota like this before, is that the truck really does not like being cold. What I mean is, Toyotas programming specifically does not like the cold. With my wife's 2024 Corolla, I hardly could tell a difference from any other vehicle I've owned between temperature changes, but it's a cvt.

The transmission control with the 8spd is very aggressive toward warming the truck. It holds gears at much higher rpm until the engine coolant reaches temp. Even manual mode won't bypass it. It then seems to prevent converter lockup until either the engine oil reaches temp, or the trans temp hits a certain threshold. I can't quite determine which without a scan tool on board. But it's something I've definitely noticed that most may not due to my specific commute. I live outside town so my driveway is immediately on a highway, which turns to interstate, then back to highway over roughly 20-25 minutes.

The result of that programming is severely diminished mpg. Much more so than I've experienced in other vehicles. A drop is always normal due to air density and increased drag with thicker fluids, but not more than 2-4mpg. Once the truck is up to temp and programming returns to normal I've actually not seen much drop in mpg, 1-2 max. I'm curious why Toyota chose such extreme measures. Between the aggressive programming, shutter system, and recommendation against long idles before driving.

Typically transmissions are not sensitive enough to require this. I could understand doing it just for driver comfort up to the coolant temp set point. But why controlled lack of lockup afterwards? My assumption is it has to do with emissions testing in some way. After owning this truck there are a few things I wouldn't mind chatting with one of their engineers about.

And a road trip, so not fair.. I drive a few times a year from the SF Bay Area to Tucson… if I am ok with drafting big rigs, I can obtain 30mpg+.. aside from where each person lives= terrain.. is one driving to save time, or desire mileage?
