first small road trip. terrible MPG

I have every confidence the "Active Aero Shutters" will turn my beast into a 50mpg Prius....... And never jam with bugs or dirt or cause the engine to overheat........

Another questionable feature - cap-less fill - somebody needs to make a cap for that! Seems like I will open the door to find water, snow, ice or dirt in the recess for the gas nozzle............

I always get a kick when the internet speeding police come out of the woodwork.

The safest way to drive is with the flow of traffic. 75mph is about the flow of traffic on most major highways. It is without a doubt more dangerous to have some righteous law abiding citizen atitude and chug a long at the speed limit while disregarding everybody else passing you.

I agree. Even though I tend to keep it within 10 over the posted limit (I learned this early on to avoid getting pulled over in WI) When I travel though large metro areas- which for me are Milwaukee, Chicago, or Minneapolis- I disregard the posted speed and just follow the car in front of me for the most part.

That said, there are still some a-holes who want to drive recklessly and try to dart in and out of traffic causing others to slam on brakes. Those idiots should be removed from the road to make it safe for others.

My philosophy in the road is: I do not cause anyone else to hit the brakes for me. I merge in and get out of the way. I wish more people would do the same.

I always get a kick when Internet law breakers come out of the woodwork.

The safest way to drive is to abide by the law and drive the speed limit. Most major highways have a posted speed limit of 70 (although there are some exceptions...I think Texas has 80 or 85 in a very small area.) It is without a doubt more dangerous to have some unrighteous law breaking citizen travel passed the speed limit while disregarding the safety of everyone else.

These trucks are just slightly more aerodynamic than a brick. Are you really surprised you got bad mpg at 80mph? If you can even call over 16mph bad. My '98 Dakota with a 5.2 averaged 12mpg combined and I have a lifetime average of 16.1 on my '15 Sierra CC 5.3.

I get great mileage at 80mph, right about 20mpg.

My old tahoe really got bad around 70mph, this truck doesn't seem to mind much until low 80's.

Saturday I drove from mid CT to Portland Maine( 200 miles). On the way I set the cruise control around 78. I only was getting around 16.7 mpg. I used 3/4 of a tank getting up there. On the way back I set the cruise lower to around 75ish. I couldn't get more then 17mpg out of the truck. Truck is a 16 custom, 5.3 6 speed with the tow package. I kept an eye on the 4cyl and 8cyl switchover and the truck was constantly going back and forth. It would never stay in 4 cyl mode for more then a few seconds. The tuck has a kn air filter and besides that its stock. When I first bought the truck I was getting around 17 around town. I do have a 1.5 level kit in the front but I can see that killing my fuel economy that much. Anyone have the same issue?

16-18 mpg is about normal for me on the interstate. Sure wish my 5.3 could get the 24+ mpg the 6.2 guys get.
