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.

      Atlas,   Then following your logic we can't believe any story that the MSM produces? I mean it's documented they heavily donate to Democrat candidates. Vote Democrat in high percentages. Many MSM talents are married to Democrat politicians, Gov. employees. That goes for on-air and off, personalities and reporters. So they would all be biased and nothing they produce is to be believed in your mind?   Again the article simply was about ways AI can be used for pricing products. Nothing discounted current situations as a factor.    Again keep looking through your left/right lenses. I don't live my life that way.   And as a heads up this thread will be cleaned up again as much of this is off topic and is receiving

      So you're saying toss the baby out with the bathwater? @txab posted article was her take on how AI can be used to manipulate pricing as it already does and has been rebuked by the judiciasry in housing. How AI can be and is used to maximize refinery or even Amazon operations all of which are true but because she is who she is; that makes what she says about what is true, false? Is that something akin to Pre-justice aka prejudice?    Look, I'm first in line to approach all information with caution just because we live in a world where people like to lie about someone or something with such a straight face and in such volume that it makes digging to the truth wearisome. Meaning I understand the skepticisms but if I were to toss out everything a person is for a view they hold then my pool of people to draw wisdom from would be non-existent and I'd be forced to reinvent the wheel daily. Not practical.    "Be innocent as a dove but as cautious as a serpent."    Test each word. Every good lie is part truth or no one would believe it. Find the truth in it and reject what isn't.    On this one, AI is being used to do what has been done by hand for hundreds of years already but at such speed, the point of a computer, that it is more easily monetized. This one wasn't that hard a lift.    I wrote a few formulas in a Lotus 123 program decades ago, a series of linked Macros actually, that allowed a daily inventory to be turned into a running P&L and production plan. Something that took three departments a week to assemble now took the time it takes to input the 'daily changes' in inventory. Later that was ungraded to the more powerful Excel program an and integrated with bar code scanning, inventory to supply was done once per shift. It had a huge impact on production scheduling, Seamless interruption flexibility, inventory error reduction, raw materials cost effective utilization and scrap reduction. Huge improvement in the bottom line. I spent months on that and AI could have done it in minutes. So yes, it not only can be used, they would be foolish to not try. The legality, ethics and morality are not the domain of AI. Humans need to keep a reign on it.

      How to Tune 6L80 Silverado transmission

      By ballencd · Posted

      New to this forum.  Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap.  I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that.  Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus.  I am also from WNC but below you in Columbus.  Any helo would be greatly appreciated.
