So new user here. I have a 2016 Silverado 2500 with the 6.0. All other engines are covered,just not the 6.0. Is there a reason for that?

What's your question about the 6.0?

If it's because nobody is posting about it, then that's because it is an awesome engine and never breaks.  Only issue is mpg isn't the best.  :)

22' Thor CHEVROLET EXPRESS CUTAWAY VAN - 2014 3500  6.0L V8  blew up at relatively low ~40,000  miles, rod bearing failure , GM long block replaced under warranty but I was renting it out to a travel company and suspect drug cartels were using it to run smack around west US.  Suspect rental company did not change oil as requested. 

I sold it once engine repaired by Galles Chevrolet  in ABQ.

Are you referring to the engine not being covered warranty wise or there not being a lot of posts on here regarding the 6.0?

      first oil change - 2026 2500HD gas

      Good thing my wife doesn't frequent my automotive forums, she might get the idea of strapping me to a handtruck and leaving me curbside for the pickers day before garbage pickup!

      Valvoline R&P Fuel System Cleaner

      By Grumpy Bear · Posted

      Okay boys and girls I put a bottle of this in Dizzy the oil burning guineapig after a tank between the coil and plug service of the #3 hole and near the end of the first R&P 5W30 attempt. As a note I did a two R&P oil changes back in October of 2025 with little effect. Granted they were 1K mile a shot oil changes so.... Then followed by fourteen  1K mile changes of Mobil 1 Euro 5W30 FS. Also ineffective.    Anyone who has followed the adventures of Dizzy may remember that to put the oil on the full mark of the published nominal 5 quart change I withhold about a cup of oil. That over the last 50K miles the P0420 light has been a frequent flyer, sometimes three of four a day. And that even on 93 octane fuel she registers some KR even in moderate conditions on favorable days on slight inclines. Lastly when giving her a kick in the pants, something done about once a week, she looks like a diesel with the pump turned up. 😬   After one bottle and over the last 500 miles of a 3K mile OCI, of the first oil change I dropped the nastiest looking oil ever in her history. That's saying something as  you will recall I have used AutoRx, HP EC30/40 and a few other harsh solvents in her before including the GM top soak twice. This was syrup. Black stinky, inky syrup but the filter wasn't all that bad.    On the second fill I had to use the entire 5 quarts to reach the full mark. That was unexpected! The ignition KR is completely gone! Even at 99% engine load. MAP is much lower. Level road is now 9.8 instead of 12.5. Fuel economy is remarkably higher and for the first time since her earliest days she will spin to 6500, more than a thousand higher with out laying down dead. Yes, the coil and plug had something to do with that but remember the first 2500 miles after that repair on the first change it was same ole same ole Dizzy. Seems we have top rings that are somewhat functional again. P0420 code only comes on now if run in town for more than an hour of stop and go. On the open road it goes weeks without a incident. Perhaps it is cleaning the cat on the pass through?  Fuel Trims have improved as well. Nothing not to like.    To early to say about oil economy but the changes to date in the operational aspect is remarkable. I can't think of a worse case than Dizzy.... It's already paid for itself in a few tanks of fuel with the mpg improvement.    @OnTheReel, I'd say if the Jeep didn't respond perhaps there wasn't an issue to respond to.    I've run the Red Line SI-1, AMSOIL fuel cleaner, GUMOUT and Techron all in this SUV without any such results. Color me impressed. I'll be running out my supplies of the list mentioned and moving on to the Valvoline R&P Fuel System Cleaner.

      first oil change - 2026 2500HD gas

      By Homer1959 · Posted

      Hey Chuck !!Thanks for the all the info I'm an old fart and I have everything I need for the oil change at home,minus flexibility .... and I’ve been doing my own oil changes for 40 years. I just didn’t want to end up without a crush washer or with the wrong one in my stash and have to walk to the auto parts store, lol. I climbed under the truck to check the location, and man, it’s going to be the easiest oil change and filter swap in the last 40 years—right up there with my 2014 Mitsubishi Outlander 2.4. No mess, nothing to drip on—just perfect. I’ve got one more free oil change to use, and then that’s it with the dealership!

      2027 3.0l - ordered

      By Atlas · Posted

      I think this subforum was created for the new generation pickup trucks (2027-) with the 3.0 but I don't think it's a big deal either way. There are probably 2027 model-year specific changes for the SUV's too.   I was just curious if you had issues with your 2025 3.0. I'm still under 10k miles on mine and fingers crossed I don't have thrust bearing issues. I'm guessing not, since you're willing to buy another one! It's a good engine minus one or two manufacturing whoopsies.
