Anyone have issue with the distance to emyty reading ? Mine only reads 550k when if filed it up.

 

Only first tank but it should still read 800km

 

Never had a problem with my last 2 trucks

I'm at 800km now and it says 160km to empty.

Should have read 800km DTE to begin with

If it's anything like my truck it's going to use what the last 50 mile avg or the last 400 mile (sorry I don't know KM off hand) was for calculating distance to empty.

 

Like for me I only drive city for going to work and to the stores, most days are under 10 miles total. So you can figure that my fuel mileage is terrible and the winter mileage is worse. But say I want to go north to the cabin and I get around 22mpg on the freeway, when I fill up it's not going to say I can go 500+ miles until empty, it's going to say I'm going run out of gas at 300 miles because of my previous fuel mileage. Pretty much the whole time my distance to empty will stay around 300-320 miles until I hit around 200 miles in, then it starts to walk it way down.

 

Not saying that is your issue but that's how it works on my truck.

Not sure I understand what's wrong with that, or what you're thinking it should be.

 

What's the fuel gauge saying?

What do you think the range should be saying?

 

It's trying to estimate how much further you can go with the remaining fuel -- so is assuming that fuel consumption will remain similar.

 

If you've gone 800 km and it says 160 km remaining, then if you fill it it the the range screen should change to predict  950 - 1000 km remaining.

Fill this thing and it says 550kn to empty. Can get a hell of a lot farther then that

it's based off your average mpg. Not an indicator of something wrong with the truck, perhaps this one is juts used or driven differently (more idle time?) than the other 2 trucks you filled up.

 

we are also in winter fuel at this point and worse mileage is to be expected.

So far on first tank I'm at 800km. Says I have over 100km left

This DTE is screwed in the head.

See what it is when I fill it up. I'm going till after the fuel light comes on at least. Just want to see how far it can go on a tank.

By the way It's hwy 70% of the time

It is base on the actual averages the truck has been seeing/recording (not what GM or EPA thinks it should get), so if at time of delivery/first fill the mpg's recorded so far were crappy then it wouldn't give a very high estimate. 

 

I'd expect that when you fill it the estimated range will reflect the actual mileage you've been getting....900km/tank, or somewhere in that range.

Finally ran out of fuel today after 2 weeks. 901km

Filled it after. Now says 715km to empty

Maybe it will go up again after next fill

Do those trucks let you see the 25/50/400 miles averages or 40/80/640km?? (the KM values might wrong)

 

See what the last two say and that's a good idea of what it's basing it on.

They do, just like the K2 trucks. And I agree. It’s pretty close, too.

My 'metric' T1 truck uses set to metric shows 50km/100km/650km

When set to 'inch' units, it shows 31mi/62mi/404mi

 

iirc, the other GMC 'metric' vehicle in the driveway doesn't use these 'hard conversion' numbers.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Indeed a proper drain tap or drain valve with adapter that has a hose on it that opens up the valve as the adapter goes on is a slick setup and have that for certain highway tractors etc and other equipment that came from the factory with a tap but this L8T is pretty darned good other than me doing it on the floor and easy to touch hot exhaust and am not as agile as I used to be !. If I really want to pull a hot filter on an engine I will use an insulated set of thick neoprene gauntlet gloves but I am not in the hurry I used to need to be so things are done more relaxed and in theory somewhat safer ... I think LOL.    And as I mentioned the unique shape of the Amsoil 1 quart containers, while they might not work as well as an offset pour spout container for some awkward engine location applications, they are working a lot better with my Lisle funnel kit because of how they prop up on all four corners when upside down resting on the rim of the funnel where the typical quart container would never stay put without holding onto it.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      Well, I just hit 100K a few weeks back, and I can honestly say I have not had any major issues with my '21 5.3 Crew cab.  I have done most routine maintenance, oil changes, air filter, tire rotations, and a transmission drain and filter change (not even a full flush).  A couple of months ago, I started experiencing the dreaded CLUNK when coming to a stop, sometimes hard enough to literally push the truck forward! After researching here and in other forums/youtube videos, etc, I was thinking it's the slip yoke. I finally had a chance to take it to my local mechanic today, and he was not able to recreate the issue.  Amazing, since it does it nearly every time I drive.  He also said he can't simply grease my slip yoke/driveshaft splines, because I have a 1 piece driveshaft.  I am not sure what else I can do.  Has anyone else had this issue or have any idea what else it could be?

      This is where the Fumoto drain valve comes in handy.  No mess and able to change oil hot, like right off the interstate hot.  Flows nice and you can direct it into a container. As for the oil filter, I use an old dixie cup or plastic one from McDonalds. It contains the oil as you pull the filter down and not all over your hand.

      Which 2027 engine will you choose?

      By Black02Silverado · Posted

      Well, if it did change from lifters to rocker arms, at least it would be easier to fix as they fail.

      HighMileage oils or stay with Dexos 1 ?

      By Black02Silverado · Posted

      Doesn't hurt to try.  It's my understanding that you have to run it at least 4 or 5 oil changes for things to get clean.  Think about it, your engine didn't get dirty in just an oil change so over time it will slowly clean. It's the safest way to do it and not have seal issues.      I remember  a product that came out a long time ago, AutoRX, it was an additive you put in the oil and then drove for 3k miles. Some saw improvements and some didn't. It was suggested to use a non synthetic with it at the time. Same observation, use a couple oil changes and give it time to work. It also stated it worked best if you could drive on trips to keep the oil hot.  I'm sure if you ask AI it could tell you all about it.
