Just a guess. Oil aeration. 

I have not heard of that yet.   Do you mean like too much oil in the crankcase, or like air getting into the pressurized oil system somehow ?

They did change the cylinder deactivation after 2014. And added it to the 6.2. Some of those failed before they left the lot. I haven’t had a problem with my new vehicles but one. It was covered under warranty. This is all for a couple miles per gallon in a controlled environment. 

How true !  I'm sure that my AFM didn't save even close to the $3500 that I spent to fix/delete the system.

Literally foaming. A crankcase is a hurricane in a tea cup. They all use some sort of anti foam, some are better than others.

Just went through a lifter failure on my parents truck. A 2016 with mileage in the 50,000+ range. Was driving around 45-50mph and went to accelerate with a little bit of force, it jumped out of V4 and went into power fine. On decel it went back into V4 mode and the next time it came out of it the lifter collapsed on cylinder 7 and had a hard misfire but still ran.

 

5 months out of powertrain warranty because of age and not mileage. I know a few people at a local shop that did the work because I just didn't have the time, it still cost a pretty penny to get it fixed. Literally drove it 2 miles to the dealership and traded it in on a new truck after the repair was done lol. As everyone knows the used truck market is crazy so may as well take advantage of it and get the most value on a trade right now. They got exactly what they paid for the truck 3 years prior, so it was a wash to own it for that time not including that last repair bill.

Is it my imagination or is it almost always #7.

If so that explains why V6's never fail

Just for the heck of it.

I had a 93 Silverado, 5.7 4 speed before my current 12 5.3 6 speed. Over 230 K miles on the 93, towed with it. 1 trans after 200+ K miles. No motor issues. 3 K mile oil changes. Trans serviced every 25 K miles. 

 

Brother in law bought a 1988 Silverado, standard cab, 8 foot box 3/4 ton at auction about 20 years ago. 5.7, 4 speed and 411 gears. It did have a new transmission. He paid $2K for it. I think it's mileage was in the low 100 K range. Truck was from a local Parks and Rec department. They traveled for over a year pulling a 30 foot trailer with it. Since then they have moved several times. He has pulled his loaded 10 K pound enclosed trailer for over 40 k miles and some other heavy towing. When he is towing heavy he run's straight 30 weight oil. He has used standard Fram oil filters. When not towing he used the recommended oil weight. 3 K mile OCI's. 25 K mile trans service. 

He still has the truck. Over 210+ K on it now. 

He has rebuilt the rear diff., the front end and a water pump.

 

Do they still build a solid truck?

I understand the frustration some have with the newer generation of trucks. Technology is great but the more there is the more problems it can cause. My 93 was so easy to maintain compared to the newer vehicles we own now. 

 

I think they still build a good product but you hear about the problems more due to the internet. I bet they had similar problems years ago.

 

As some of you know I'm a firm believer in above average service intervals. I believe it pays in the long run if you are going to keep your vehicle for an extended period. 

 

YMMV

    • 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.     
    • 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!
    • 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.
