The best I've gotten is 415. I get between 375 and 400 on a regular basis though. 26 gallon tank by the way.

 

Combined city and highway driving I get about 480 miles to a 26 gal tank. Sound good?

 

sounds amazing, are you 2wd? ive got a 23 gal. tank i think and i get around 285 to a tank i believe. overhead reads 12.3 mpg.

 

I have a 34gal tank, and when I fill up, it’s usually at around 1/4 of a tank. So on 3/4 of a tank, I get around 350mi during the summer, and during winter it’s usually around 300mi.

 

Yea it's a 2wd with an Airaid CAI, 3.92 gears, and 20's. I drive it pretty easy unless I feel like hearing it roar.

 

i think around 550 with city driving and if i do only HW its around 650-700... 35gal tank and i like to sit behind truckers and draft, around here they go 75-80 in the 65 zones

 

good grief man!!! i wish the truckers here would go that fast!!!

 

i have a 23 gallon tank and I get tired of filling up every 250 mi. Anyone wanna trade me for a 35 gallon tank??

 

How are you driving/What are you doing to get as far as 450?
I too have the 35 Gal tank and cant get past 400.

 

In your case you have a lift kit and bigger tires am I correct? That lift kit will create a lot more drag for you and thus make the engine work harder. The tires are the same deal, especially if your gearing is less than 3.92. I always heard if you are going to get bigger than 33 inch tires then you should have at least 4.10.

-Keep your tachometer under 2200 RPM.
-Get a CAI and/or a tuner. I have an Airaid CAI.

I get about 450-480 miles on a 26 gal tank.
