New guy here...   Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.    Long post, so

When I was shopping in November, I had salesman tell me: -1500 diesel didn’t exist -it’s a duramax/Allison so it will last forever -It’s a 1500 but can pull like a 2500 with the diesel

I have been driving a Duramax Diesel for the last 15 years, 1st a 6.6 on a 2500HD and the last 3 years a Colorado with the 2.8L.

Outside putting Diesel and DEF fluid, there is no difference from a gasoline truck. I have never worried about regeneration and stopping. The truck does what it does when it needs to.

 

On all these years, I drove a combined 370,000 miles, only repairs so far, injectors (recall under warranty) a fuel pump, a water pump on the silverado and now the Colorado is asking for a DEF pump (under emission warranty). outside this, oil every 10k miles and that is it. 

 

Now I am looking at the 1500 with the 3.0, I love my Colorado, but it is getting small on me with the family. 

 

Hoping this thread goes back to its original track.

Read it here, you can’t stop during regen. That’s the only comment I made about that. I didn’t mention the cost replacing those emissions parts when they fail. That I’ve heard from owners who choose delete instead.

Point is that you can stop during regeneration.

 

Whoever told you otherwise was wrong.

WOW, this sh$t must really bother you. Boys and Girls do your research. Don’t just believe us. If you do short or moderate trips you could be forced to do a regen periodically from what I read. If you do long trips routinely your probably just fine. I don’t know why anyone would be against doing research. It wouldn’t be a fit for me. Most of my trips are 9 miles or less, except 3 times a year I round trip 3K miles.

If you research it, you will learn that indeed you CAN stop during regen, the truck will try to continue the regen next time it runs. If because your driving style it can not complete the regen after multiple tries, it will advice you and all you have to do is drive above 35mph for 20mins or so, btw it doesn't have to be a single drive, multiple drives above 35mph will complete the regen. Also there is a process to force a regen with the truck parked, but I have no experience with this. 

 

But honestly you should start another thread to discuss regen if you like, that is not what this one is for.

So the effect of regen shouldn’t be discussed in a diesel thread, ok. I was actually interested in one because of the mileage. The fact that I would make a special trip to regen probably shouldn’t be considered. Got it.

Thanks SkiDooNick700 for the videos'!!!

Could you please provide more of your towing specs?

I would like to know how much weight your towing and how your truck pulls at highway speed, i.e. down shifting, RPM at 65 MPH,

tow haul exhaust braking and anything else you could address.

Again Thanks!!!!

Drove another 150 miles this afternoon at speeds from 68-75 through rural highways with going through towns and about 40 miles on interstate. Had a really good head wind about half the time, I'd say around 25, and averaged 25.1 according to the computer when I got home. Didn't think that was to bad considering the wind.

Congrads on your new truck!!!

 

What color did you get, it looks different in the sun with blue sky than in the shade, I like it.

How is the 10 speed now that you have a few hundred miles on the truck?

Do you plan on towing with this truck??

 

Thanks

Truck is satin steel but definitely looks different on different light. Liking the 10 speed so far, amazing how smooth it is, can barely tell when it shifts under light acceleration. Don't plan on towing much, mainly just a pontoon or tractor a few times a year. Mainly bought for mileage as I put a lot of miles on going from job site to job site to check on my landscape crews. Just needed the longer box to haul materials around.

That’s not really added cost to owning a diesel though. 

 

I’m sure there’s going to be problems with the emissions junk at first (I had one in 7 years, 2 different trucks 200k km total) but that’ll get sorted. If you delete it before it’s out of warranty then you should know you’re assuming a lot of risk especially with a new generation. 

If you can find anyone to delete.  All the major players and reputable tuners are no longer offering delete tunes.  Only Joe in a  garage at the end of town might do it, if you are stupid enough to trust your investment to him and knowing that your vehicle will never go into a dealer again for anything.  The EPA is really cracking down on this stuff.  They will even get dealerships involved in reporting and even forcing the customer to pay to put the vehicle back into compliance.  Of the tuners that have offered delete tunes, it is rumored that EPA is wanting their invoices from these deletes so they can track VIN numbers and go after individuals.    PPEI, Banks, Bully Dog, PDI and EFI Live are all out of the delete game now.  EPA went on a major crackdown in the last few weeks.  PPEI was the last holdout to cave in. PDI got hit for 1.1 million dollars in fines.

Wow! That’s pretty interesting and I didn’t know that. I did research on deleting my last two truck (2011 LTZ duramax/2015 Denali duramax) but never took the plunge. Warranty to me on those diesels was more valuable.

Of course, California is really anal about this stuff.  It has been reported that they are now randomly stopping pickup trucks and look to see if SCR/DPF units have been deleted.  And as we all know, as goes California so goes the rest of the nation.   The Feds are the ones behind this, so it really doesn't matter where you live or whether you have state emisions testing if you think it will not affect you.  If one already has a deleted diesel, likely will never have an issue as long as the keep their fat mouth shut and not go around rolling coal and other nonsense. 

 

What we can hope for is that, according to Kory at PPEI, there will still be allowed performance tunes that keep things EPA compliant.  I still think that someone might slip in a section of code that turns off EGR which is the main culprit in soot production and in creating the majority of problems with the motor and downstream stuff.   So by all appearances, things will be in "compliance".   But I think it will not be for a while till some try to slip this kind of code in. The eyes of the EPA are on everyone right now. When the dust settles, maybe.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
