Fuel economy

Not typical of my usual driving, but I set my cruise at 55 mph on the Natchez Trace Parkway (where the speed limit is 50 mph) and you can see from the photos what kind of gas mileage these trucks are actually capable of driving in this manner (with a generous mix of hills and flats). For that gas tank I averaged a little over 27 mpg.

 

The 2.7L engine must have had refinements over the years for fuel efficiency. Getting in the upper 20s in a mid sized truck is great.

 

Big changes to the 2.7 for the 2005 MY ( Went from 3RZ-FE to 2TR-FE). No big changes past that. Toyota changed the engine to have variable camshafts for both the intake and exhaust for the 2015 2.7, but I don't think that made too much of a difference, as the truck also gained hundreds of extra pounds. The big change for 2015 is the manual transmission got a lower 1st gear (very nice.)
In my 2009, I get between 20 and 26 mpg.
Winter and city driving, as well as speeds over 70mph drop my mileage noticeably.

 

On an 03 2.4 2WD MT I can get 27-28 on the highway and 23 mpg in mixed driving but then I drive like an old man and am proud of it.

I don’t know the rear axle ratio but for the type of towing and hauling I do it’s more than sufficient and probably at least a little better than the 2.7 with 4wd.

 

Interesting then my 2007 engine isn't very significantly different than a new one. 20-26 mpg is great, I'm on the lower side of that. I rarely exceed 70mph. I figured in a truck faster speeds would impact fuel economy more than a car of SUV.

The mileage you're getting is better than my 2.7 with 4wd, also manual. And old man driving here too, I guess if you don't exceed 70 mph on the highway you're in that category. I'm also proud of the driving style, it should help fuel economy at least a little bit. And the way fuel prices are now, that little bit can be significant.
