What gas mileage does your ‘17 1500 get?

I have owned three of the 5.3 Ecotec3 engines prior to my current 6.2 ecotec all of which managed consistent low 20's for mpg with about 90% highway (completely stock). More specifically to answer what I think the original question was I never noticed any significant mpg improvements in any of my new trucks the mpg achieved over my first 5,000k was consistent though to ~50,000k

 

My guess is the mpg you are seeing now is what you will continue to see, dont expect the truck to drastically improve. 

 

 

Yup, unless changing driving habits dramatically your correct.....

my tires are at 35 psi.. the truck is completely stock.  i am confused.  i use cruise control on the hwy at 65mph.  so what am I doing wrong to get 17.5 mpg w conservative driving where you guys are getting 20?

Could depend on a number of things. Where do you live for one, are there a lot of hills and what elevation are you at, what fuel do you use?

i live in florida.  its flat for the most part.  i use 93.  could it be 6.2 vs 5.3?

i'm averaging 19.5 with remote starting it to warm it up in the mornin/evenings with 3.42 gears

I did a little experiment driving from work to home and then from home to work.

I tried to see if setting the cruise lower would really get better MPG. It didn't.

 

With the cruise set at 88, I averaged 19 mpg. Same distance with the cruise set at 77 and I'm averaging 16.5 mpg.

 

Shouldn't it be the other way around?

18.0 lifetime average including highway/city/all towing. Normally returns 22-23 on highway trips unless I run over 74 mph. Lowest it has been on a weekly work commute average is around 14.5 with remote start warmups/colder weather and winter fuel. Summer weekly work commute averages 18-19. 

This is just about exactly what I’ve been seeing on my 2017 CC 5.3 with just under 6,000 on it. Although I did hit a high of 25.3 on a 3 hour road trip. But I have definitely seen a big decrease now that winter is here.

Yep, my weekly commute has dropped to 16-17 average with cold temps/winter fuel. My garage is cleaned up now so no need for remote starts and all the fluids are warmer starting of a morning. I have seen about a 1 mpg difference average this week parking in the garage. I got 25.2 one trip down to Tennessee but I was following a friend towing who's vehicle lost speed up hill so I was slowing down up hill.

 

I wish I could just ignore MPG and say " I just put gas in when it needs it". Ha.

I love it when people hope for 18mpg out of a lifted truck. You are lucky to get that stock in reality unless your truck is for freeway cruising. I seem to get better mileage with my 6.2L on 33's than my 5.3L on 31's, probably because my foot is in the 5.3L trying to make it move like the other truck, combined with winter gas and winter idle times. I average 13.5L/100 (17.4 USMPG) with the 6.2L on 91octane and 15.5L/100 (15.2 USMPG) with the 5.3L on 87octane according to the computer. More like 15mpg and 13mpg in reality.

19.9 mpg on the dial 45K an absolute marvel of an engine and Trans for the most part!

 

Just because it is 8l90 8speed and the learning took forever!

I recalled that my tires were underinflated at 31 for about 1000 miles.  i took delivery that way and it never chimed so I never thought about it.  my average was understated because of it.

 

presently, I am averaging 21.x MPG on 300 miles after a reset with the proper pressure with the same factors I noted before.
