I bought my truck & then drove about 200 miles of interstate to get home. I averaged 21-22 MPG, going 77 MPH, with an outside temp between 85-90 degrees.

Took ours on an 1800 mile round trip and got the same. Definitely better than our 99 5.4L Ford.

I think if I was a salesmen I would research the products I would be selling. I wouldn't like it if a customer came in knowing more than me.

Mine gets pretty bad mileage at 180 mph. Maybe I should get a bed cover.

This was taken last week when I filled up. So far I have put this many miles on the truck. Hopefully it stays like this. We will see.

Just traded in my 2014 silverado 5.3/6 speed with 3.42 for a 2015 6.2/8 speed with 3.23 In stock form, 2014 averaged 18.2 hand calculated at 75 cruise control for my weekly 350 mile trip. First trip with 6.2 at 75 cruise control was 20.8 hand calculated. Awesome truck and wish I had traded sooner. I added wheels/tires to my 14' and mileage dropped to 15. I'm still debating if I'll change wheels/tires on my 15.

A recent trip 150 mile round trip. I have the 5.3 crew cab. I have 24 inch rims and tires so I think this is good.

Yes it's an open trailer. The trailer it self is 2000 lbs and I had a 850 lb 4wheeler and 250 lb mower and probably anouther 100 lbs of stuff on it.

What is the max range you have seen?

 

 

 

 

 

 

That's easy to do if you reset the trip meters just before you head down a long pass!

 

Let's see your best averages!

Oh and I have a 6.2!

I would show my 400 mile average but I have been towing my camper in the last 400 so it's nothing exciting

But you really can't fake the 50 mile average! I got these numbers on my last trip to Denver and some of it was in rush hour traffic

So, how does the computer figure out the range? Are you saying it is using one of the trip meters? Great 6.2 results. You have a nice 3.1l in 4 mode.

 

This was a nice country road drive. (4.3l 4x4 AT tires)

36550

 

This is with my daily short all city commute. (This is pretty close to the hand calc.)

Range is simply average fuel economy times remaining fuel. The average fuel economy used is not based on the trip a or b unless you've not reset it in awhile.

Not sure that makes sense. Is there a hidden lifetime mpg? It would make sense if it used the last 400 mile average. It does seem to recalculate the number on the fly as you are running lower on gas. I did a highway trip a week ago with speeds around 80, so my mpg was below 20 and it seemed to change the range accordingly as fuel was running out. But, I may be mistaken.

 

Is there any info out there on how this is calculated.

The manual only says the fuel range estimate is based on the average of the vehicles fuel economy over recent driving history and the fuel remaining. It also says the range may not be reset.

My bet would be 25 or 50 mile fuel economy is used. Below 50dte I get low fuel warning.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
