What kind of MPG can be expected with the Tundra? Some say it is horrible, some say not.

My GMC gets 15 city, 17 hwy and 9-10 towing the camper.

My Tundra was lifted with 305/55r20 AT tires and mileage wasn't any worse than others. I would get 17mpg hwy, 14mpg city and averaged 9.8mpg towing our 34' 7600lbs trailer. I could probably get better but tend to have a heavy foot on the highway. All hand calculated, even though the computer was pretty accurate. The 5.7l with 4.30 was a bulletproof tow beast. Pulled way better than my current truck.

The 2016 and newer Tundras have a 38gal tank.

Tundra hasn't changed the 5.7 or the tranny since 2007. The EPA ratings have consistently stayed around 13/17 to 14/18 depending on the year, and whether it was a 4x2 or 4x4.

We used to own a 2012 Tundra 5.7. Got 8-10 MPG towing a 7,000 lb. trailer. Under ideal conditions we got: true stop & go city 12-13 MPG; suburbs 14-15 MPG; interstate 17 MPG at 75-80 MPH.

A friend of mine has a 2015 F150 5.0 V8 with an EPA of 15/21. It consistently gets 2-3 better MPG's than our 5.7 Tundra under the same conditions. HP and torque numbers are very similar even though it's a smaller engine.

I've driven a number of F150 3.5 Ecoboosts. They each got the same MPG's our 5.7 Tundra did. Very interesting in light of the fact the Ecoboost's EPA ratings are 3-4 MPG's higher than the Tundra 5.7.

As I posted earlier, my numbers don't check with yours. My 3.5 EB gets a measured and calculated 17-18 for general driving. Very little is "city" driving. Although it has been to Denver a few times, most of my driving is rural and small city (15,000). My last fill was 29 gallons and 517 miles = 17.8 mpg. At 75-80 on the freeway it's 18-19. Not a huge difference, but slightly better than yours. I like that at 70 mph the engine is only turning 1800 rpm - barely cracks 2000 at 80.
