MPG did improve
 When I was shopping for trucks I was driving a Ford F-150 “2011”.  This is the first Toyota I have owned. The dealer did informed me that the Tundra was a nice truck, built well, but gas mileage was poor. When I drove the truck the impression I felt was this is a solid truck! For the first 3000 miles my average mileage was 12.7 mpg around 5000 miles the average is now 15.6. My hi-way mileage is around 17.8 mpg @ 70mph and is 15 mpg @ 85mph (live in Montana). I always receive a compliment about the ride a feel of the truck from my passengers.  I enjoy driving the truck and would not think twice about purchasing the truck again.
