Poor fuel mileage

I am wondering if my fuel mileage will get better or not. I am currently getting anywhere from 14-16.7 mpg. I have a 2021 Tacoma TRD off-road with 2800 miles on it. Seems to get better fuel mileage when I shift it into sport mode and manually shift it. The dealership told me it would get 18-23. I'm not even getting close to that!

 

I think in the beginning it sucked on my 17 for a little bit then I was getting 19 mpg average...at least according to the computer.
Later on when driving on long highway runs it would show 21-23........I think I snapped a pic of it showing 32! ......that's driving grandma style, if you're a lead-foot it'll always suck.


I'm not sure where I'm at now because I put on cooper 255/85/16 and the speedo/odometer are not calibrated for that.

 

All depends on driving habits and environment. Winter time, hills, short trips will give you suck mileage. Summer, long trips, no mods, good driving habits? Good mileage. It's not the truck is what I'm trying to say.

 

Winter gas and City/highway driving,,, yeah 15 about right. Even less for colder temps, long warm ups, hills, etc.

 

Winter fuel and new engine. Give it a few thousand more miles.

 

The fuel mileage on my '06 TRD OR AC started reaching decent values around 40K miles. Stayed pretty consistent and often better after that.
My '21 TRD OR AC at 1K miles has been 15.0, 16.6 and at last calculation 17.8. I expect it'll get much better as it gets 'broken in' and as I get used to it.
It all is influenced by your miles driven each time you start it up AND how you drive.

 

Nice prius.

 

In my 19 bone stock, I was getting ~18 city, and highway cruising at 60mph. Anything over 65mph and it dropped to like 17

 

wrong guess, but nice projection.

 

Are you looking at short trip summaries on the display or calculating based on tank refills? Long trips on the highway will be fairly accurate short trips no. I calculate based on fillups, that’s the most accurate.

 

Probably won’t get better. My full tank always says 256 miles to empty. 255/85/16 tires.

 

This truck's MPG is highly dependent on the terrain and gas pedal pressure (acceleration). I drive like the proverbial old lady and drive like there's an egg under my right foot and the truck has averaged 22.7 mpg over 70,000 miles. I'm not the only one here on TW who gets decent mileage. It really depends on how you drive it. When I visit SLC and drive up the steep Cottonwood Canyons to go skiing the mpgs take a big hit. But here in CO I can keep the mileage pretty good. Given your low mileage some folks have found the mpgs get better with more miles as the transmission is still in the learning phase. Hope yours goes up too.

 

My truck was at around 12 mpg when I first bought it and now its at ~18mpg (still basically stock until next month )

 

I hover right at 16 now, 106k miles. Armored with 285’s and camper shell.

 

Could it be this particular 22.8 miles - Monarch Pass to Salida?

My mileage improved after 5,000-8,000 miles. I get 18 mpg going 70 mph on the highway. MPG drops rapidly above 75 mph.

 

I get between 12-14 on an OV tuned 3rd gen on 34’s lol

 

I have a 2017 TRD off road dc.In the winter with the winter fuel mix I'm getting about 17 to 18 at 47k. In the summer I get around 22.

 

It’d look more like this if it were Priusy:
