What's your 2023 Tundra's Real World Fuel Mileage

For fuel economy discussions, I recommend 3 tank averages. Fuelly is a good source for both data and recording your economy. Dash readouts are good for anecdotal bragging rights, but that's about all.

 

50mph tailwind? Oops, sorry, 80Kph tailwind?

 

the dash read out has been dead on balls accurate overtime Ive checked it, my old tundra was the same way.

My ram was always higher reading than actual by 2-3 MPG

 

Most my driving is hwy

Stock tires in Wisconsin in the fall: 20MPG
AT tires in Wisconsin in the fall: 17MPG
AT tires in Wisconsin in the winter: 15MPG

 

did you go up to load e? looks like it from that big of a loss

 

Yes they are load e. Stock size though and 18lbs heavier than the factory Yokos.

 

ya, that sure explains it, plus winter blend here in the midwest is total shit

 

My little electric BMW is a great way to show me what happens when you go faster. If I drive at 50 mph, I can see the battery drain slowly, if I bump it up to 70 mph, the electrons start to move quickly, at 80 mph, the electrons are being flushed down the toilet!.

Slow down if you want better mileage. Like @Mattedfred diving closer to 50 mph will produce great economy, but in @Eurodriver example, the truck has the aerodynamics of a barn rolling down the road and running at full boost is just sucking the fuel!

 

Thanks - that's perfect now!

I’m at 11.8 with my TRD Pro. Not very good, but if anyone can help me understand. I do run bigger tires, 35/12.5/r18 BFGs on stock TRD pro wheels. My truck now runs 3 miles slower than real life shown on my GPS. IE odd shows 30 miles an hour, GPS now shows 33. Should my actual real world MPG be better than what my car shows? Any easy calculator to show how tire size change effects MPG calcs?

To be fair, I got a big RTT, heavy rear load in general running around 500-600 lbs with all of our overlanding gear. Roam boxes up top. Not to mention frequently doing road trips in Texas driving 90-95 miles per hour.

 

My thoughts. I have 34.3" tires on my TRD Pro so have done some (probably shady) maths.

Yes your MPG on the truck dash will show lower than actual, as your bigger tires throw off the odometer. You are actually going further than the odometer says as it is calibrated to stock tires (~32.6")

To calculate actual MPG take your 35" tires actual diameter (from discount tire or tire rack specs) and find % difference from stock. Then use that to correct odometer reading (i.e. my tires are about 5% bigger so I multiply odometer reading by 1.05 to get actual miles traveled).

I see about 1 mpg estimated improvement over the dash reading when I apply this logic.

My 295/70-18 Nitto Recon Grapplers are "S" weight range vs "E" on most every 35" tire so are a little lighter and a little smaller. Showing 16-17 mpg on the dash in normal driving so likely about 17-18 mpg actual.

 

lol shows our tundra in the 2023 overview pic (middle one)

 

With forced air induction vehicles the more boost you use the less mpg you get. Ford named theirs correctly. Eco or Boost, your choice.

I read an article about why booted smaller displacement motors are capable of so much HP/TQ. Basically at 14.7 psi boost (equates to approx. twice atmospheric pressure) your volumetric capacity doubles.

A 2.7L turbo motor is now a 5.4L
A 2.3L is now 4.6L
Funny how Ford made them that way to match their V-8s at the time.

3.5L now equal 7.0L at that boost level. This is why they are worse on gas than their Naturally Aspirated counterparts at high boost. When not in or using very little boost you have small displacement and more mpg.

 

Ill take a boost boost motor, keep the eco, HA

 

At least the branch didn't get to the radiator behind it.

 

thats 0 fun dude, boost that bitch one in a while and let it eat, its fun

 

How many katahdin sheeps is it?

 

LOL, Your Lucky Day!! Haven’t noticed mine up front yet. Great App though.

 

Just in time for the Christmas Season, careful, you'll poke an eye out...

 

Natural selection at it’s peak lol

 

Humans poke themselves in the eyes at times too without ever realizing it.

 

Look, if you pinched the radiator and have about 4 rams in truck's bed, they can tow the truck to the dealer and get slayed to cover the parts+work. You can probably even get paid by Ford or GM for that show in front of Toyota dealership.

 

But there ain't no tow hooks to hitch the goats to

 

Oh sh*t, well planned, Toyota! They knew it could happen!

 

Most trips I’m averaging 16-17 with a 3 inch lift and 35s. If I do 50-55mph I’ve seen 18-20mpg on some drives. Tire size comparison tool showed me that stock vs the 34.5 diameter of the new tires it’s off by roughly 6.2% so after a correction on the dash readout I’m at 16.1 after a thousand miles, way better than the 11ish mpg on my 5.7 with similar mods

 

Can it be any better?

 

Well, technically since they are rams, they are likely to be best at pushing from behind anyway. See Wise Toyota.

 

It is nice to know folks haven't changed. This was a common compliant in the F150 forums when Ford put Ecoboosts in them in 2011.

My car isn't getting very good gas mileage. I only did a few mods....

 

And my front end shakes. Toyotas suck.
