OK, sure, it's just over a 25 mile range, but it's still the best I've seen in the 28k miles on the truck so far.  I'm not sure what changed, but recently my mpg just seems better. Overall, I'm still at 17.9. I'm curious what others have seen as their highest recorded mpg. I hit this 32mpg on my way home from work last week,  it's actually 110 miles round trip from home to the office and back, mostly on back roads and in sport mode, using cruise control at about 60mph most of the time.

Yeah i can only laugh at some of the estimate mileage ratings from people here and not a chance is either a 5.3 or 6.2 getting 30 mpg, not unless you are driving down a mountain.🤣

my best was 33.5 with 0% ethanol, so if your using E that is outstanding.

 

Wish I could get my GMC off 50 mile ave

I tried my best never to reset my 2nd trip meter for the life of my truck, half way in the dealer reset after some warranty repair... pissed me off but here's still a respectable number:

That would piss me off!

 

Did you have the information turned off in the information page selection list?

 

I've been using the information page selection list to 'turn off' trip 2, thinking it prevents accidental resets in service or by other drivers.

 

Since at least 2015, I've had no 'trip 2' resets. 

It still records even when not enabled for display, so if I want to see the data I turn it back on, read the data, then turn it back off. 

 

 

Anybody know if there are service procedures / updates that cause reset to the DIC data?

That was taken a couple year ago.. a long drive from Dana Point to LAX Airport. 130 miles roundtrip. Not a diesel either and this average was based on 50 miles so that wasn't too bad. CC was set at 60 mph and the speed limit ranged from 55 mph to 65 mph.

 

Pretty good for a 5.3 with 4x4 though...

You live in Dana Point? I have a house there, don't know if you've seen my truck around, it was a 2019 Cheyenne RST 4x4 with Mexican plates, it spent most of its time in Dana Point though.

I drive my wife’s car every Sunday to church. After I put gas in it. When I get in usually it says 19 miles per gallon as her weekly average. I baby it home anticipating the lights gentle on the gas pull in the garage at 25 mpg. It’s good for a laugh.

I remember my first 5.3 powered Chevy pickup 2001 Z71 ext cab. Back then we had to do mpg the hard way... Well the first time I penciled out 20mpg overall on a 200 mile trip, I hung the gas receipt with the miles and result on the fridge.

That’s pretty good. All the Z-71s I had came with 373 gears. My 02 avalanche at 70 gets 18 mpg with the same gear.

Mine was 3.55s  and that trip was a mix of 60 and 70 mph. Also mind you that was back before our gas went to sheet with our base gas still at 87 octane and one of additives being banned by epa

      2027 GMC Sierra: Official Discussion

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
