Just would like to see what everyone is getting on the highway for some research.

I made a 200 mile trip yesterday, pure highway and got 25.2 MPG hand calc.

 

Truck in signature. Running 65-70 on cruise 17-18 hand calculated.

 

Depending on all conditions I get from 19.5 to 23.

 

455 miles one way to include about 100-120 miles city driving 19.43 mpg.

 

I am assuming less than 20 - although I have seen short highway trips over 20, but the only time I have run through an entire tank on the highway alone, I have been pulling a trailer... so I cannot say for sure....

 

My best ever is 25mpg running between 60-65mph on the highway nonstop.
Smarty set to level 3.
My typical average is 21-22mpg highway @ 70mph.

All freeway best has been 23.3mpg at 68mph.

I normally get about 20-21 at 70 with my current mods with Quad at 100hp setting.

 

depends entirely on the load being hauled
running empty? I have an 06, with a 6 speed @ 60 mph i can get around 23-25 based on the OH readout..which i know is wrong...but i drove to vegas the other weekend and back on one tank from san diego which is around 700 miles

 

Seems like those 2wd boys are getting way better mpg....

 

The only time I got over 20 mpg was on a road trip to Arizona in March 07, on the local Hwy which I take a little bit to work, I ususally get around 17+ if I drive in a reasonable fashion.

Fun factor takes it down to 16+.

 

Cruise set @ 65mph I got 25 constantly.

 

Coming home from Seattle, going from Medford, OR to Redwood City, CA plus driving to work two days I got 22.05 hand calc driving 65 to 70 on the highway. Truck is stock '06 Bighorn Quad 4X4 long bed 2.73 Auto w/ARE hard tonneau (haven't figured out how to fill out my signature yet). Overhead read 18.9 mpg. I find my mileage to be speed dependent. On a trip to SD this summer I got from 17.5 to 19 mpg straight Interstate doing 75 to 82.

 

2.73 gears?

 

if i set it at 65 or under i get 25 ish hand calc. but as soon as i do 70 or more it drops to 20 or less.

 

2005 2wd Auto tran. the best I have done is 21mpg, totally stock. But that was with the criuse set at 78mph
