Averaging around 15.5 - on a weekend trip with the mrs, we bumped it up to 19.4 ( as indicated by the overhead console)

I did not buy this truck for mileage, I bought it to do the things trucks do, do them well, and look good doing them. I tend to drive like a grandmother unless I get pole position at red lights. Usually though, cruise control is my friend.

 

On the way back from dallas I got just over 18 mpg on the highway. Thats going between 70 and 80 with a 3.92 rear end and 35's running 87 octane. Since I put the 35's on I get between 9 and 10 intown though lol.

 

You know, Ive tried to slow down but do you know how slow and how hard it is to keep the RPMs (in any gear) under 2000? My truck loves the 3k mark for some reason.

 

im getting 12.6 according to the overhead. and i rarely go over 3000rpms. i was at 13.1 when i was going to school.

 

when i run 89 I get 12.4-6 and when I run 87 in the thing I get 11.5 so it pays to use the 89 and when people claim 20+ thats ridiculous unless its highway almost no truck will get that and I would want to drive it myself to prove those numbers
