My truck is getting Awesome gas mileage . Today we traveled 150 miles on secondary roads that were multiple changes in altitude and turns .My speeds were from 45-65 mph with about 14-16 starts and stops through small towns. We average 25.8 and I’m wondering how other drivers are doing with the 3.5 liter w/ 3.55 axle . Yesterday. It was 26.5 in about 80 miles. Looking for input

 

Just bought a 2023 F150 3.5 ecoboost with 3.31 axle, would like to know what MPG I can expect.

 

Under perfect conditions 60-65 mph I might get 22-23. When pulling a 7000lb travel trailer I get 9-11

 

So far I'm happy with performance and MPG, got a total of 7000+ miles now, accumulative avg showing on truck is at 22.3 MPG, including a little trailer pulling, less then 100 miles I'm guessing. Did some long distance trips on interstate that averaged 23-24 MPG, best was 25.1 on secondary Hwy.
