what kind of mpg do you get?

Last summer I was getting 6.7-7.1 consistently between fill ups. One it got cold I dropped to 6.3-6.4 then got really cold and got 5.9-6.1. But now it's warming up a bit so I'm starting to improve. Also I drive a faster now than when I first got the truck.

 

Im getting around 4.5 to 5.0.........Then again,I dont really care either...

87' pete 362 pulling a 96' 48' flatbed ...Heavy hauls..Heavy Trailer... Wheels hopping and motors growling.. 350hp Cat 3406B

 

5.7 mpg after the valve adjustment. Was 5.1 mpg before exhaust rocker arm cracked.

 

I was just looking for someone that would agree with me and maybe tell me something I don't know. Yes, my "boost" and "pyro" gauge's are on the left, down low. I have thought about moving them to a better place. I have also thought about buying the scangauge because you can adjust the "avg mph" to make it closer to what your truck is actually doing. I am wondering if mine, on the display, can be adjusted in the ecm...hmmm?

 

Why don't you care about your fuel mileage? The better the fuel mileage the more money in your pocket.
