No, I went down to 5K oil changes. I used to run 25K miles on Amsoil. 12-15K on my trailblazer ss. I was an extended guy. I bought all in. I changed with cylinder deactivation. Then turbo charging. My Genesis dealer recommended running the extreme service schedule. I joined this website and people pointed out to me that these modern engines require more frequent maintenance. So if I spend an extra 100$ a year shorting me oil change intervals no big deal. Especially if I want to run 200K miles. Then you add people posting their oil analysis. It took me awhile to be convinced. I was giving the same argument as you 10 years ago. Oil is cheap and I’m not trading in before the warranty is up anymore so yeah I’m going extreme on maintenance.

If you have fuel dilution happening to the point where it significantly changes the viscosity-related properties of your oil, you are going to have a lot of other issues before you have lifter issues. But you aren't wrong per se.

Well you don't know what happens with higher-than-5k-mile oil changes if you don't go higher than 5k miles between changes.

Yikes how did you get it out as there is only enough space to pull the filter out, i usually rip a piece of the filter box cardboard and try and create a dam on the underside of the filter so stuff doesn't just fall past it once you pull the filter out. But to those with smells and you have never changed your filter? Give that a try, even better K&N makes them and are only double the price of a standard one, and of course it will be the only one you will ever need to buy again. Plus I here it helps with the flow of your cooling and heating system as like with a k&n air filter it is higher flowing then stock.

Hi curious if anyone with a ‘24 LTZ has swapped their center wheel caps for ones with the black bow tie. i see the part number for some is gm# 84267795 I have seen posts where some say it will and some say it won’t. Believe these were on the RST stock

It doesn’t take as expert to see that wasn’t a good move. If you were going down that hill and placed your wheels differently maybe if there was an emergency. If that was a high flow ditch that removed soft material maybe doable. I wouldn’t had chance it especially how sensitive environments can be.

My thoughts exactly. If the ZR2 does have more travel, etc why are new upper arms not included in either the TB or ZR2 kits. @AJMBLAZER, can you post the ZR2 part numbers? Might bite the bullet and just order them if they are not too pricey compared to aftermarket ones. Just to see if I can see any visual differences compared to the non-ZR2 arms.

I have started this project as I have had **some** free time. I've had the parts for some time sitting the garage. But finally able to get the Denali Seats installed into my 2021 Silverado LT along with the center console and rear heated seats. Driver seat memory is operational! Heat is retained, cooled not working (also waiting for WAMS for the release of BCM Programming). But being able to get power folding operational relies on Driver Memory Seat Module (MSM). Swapped out driver side and all but power fold worked. I can see the mirror trying to fold but limps in its attempt. Think these mirrors have junk motors in it. They are also Sierra mirrors and don't quite sit flush so I'll be on the lookout for Silverado mirrors. The door handle swap had some melted "rivet" type fasteners that I had to pop. So that sucked LOL. Passenger side - EXACTLY like @Rally6.2RST stated. So I'll be following his workaround for now to regain passenger window control. Key fob fold works, power mirrors adjust works, reverse tile, mirror memory, etc. works. Puddle lamps not working at the moment and don't know what drives the front spot light at the moment either. More to come. Thanks @Rally6.2RST for the support so far!

Well, as a onetime Amsoil dealer and user and extended user. I agree in some cases. With cylinder deactivation, turbo charging and DI engines. And a person called Grumpy and his posting. As well as my change in driving miles with retirement. 5K oil change intervals is my max. I might add. You’d be hard pressed to find an individual who has more experience with oil, oil brands than me. I sold equipment for 40 years. That may not make me an expert, but I’m experience.

Not going in, but perhaps coming out. Foaming has the same effect as starvation. Fuel dilution is a viscosity breaker, right? Fuel enhances foam. Just thinking out loud. When oil becomes compressible hydraulic function goes sideways.

I’m too old and broke dick for this.

Here’s my retirement maintenance volunteering. Operators drive me nuts. Decided to take 140m2 grader via a short cut on wet mountain road spring thaw. Hung up 644K and D6 being an unsupervised idiot.

Man's got'a eat, right?

I had a 2010 Tahoe Z71 (5.3l w/AFM) that I put 210k miles on. I changed the oil every 7500 miles with Mobil 1 5w-30. The new owner is a friend of mine so I can see the trucks future. It's at 225k now, still no issues. Before I got rid of it, it was experiencing what appeared to be a low oil pressure issue that (after two months of troubleshooting) turned out to be two bad sensors in a row - but during those two months the dealer opened up the engine because they thought it was the oil pump - and they were absolutely blown away by how perfect that thing was...they said the internals are like new. One tech and one service writer both asked what I would want for it - unfortunately I had already promised it to a friend. Based on the extensive data i've collected on the lifter issue, it has nothing to do with oil change intervals (obviously excluding negligently-long intervals). It's an oil-starvation problem, not an oil-quality problem.

Evan Williams Honey Whisky is mine. Margaritas when I play cards. Bloody Mary if I get hungry playing cards.

I was asking literally. The trucks oil and OCI not yours My daily lube is Evan WIlliams black label. My Sunday desert is Woodford Reserve Double Oaked.

I advised my brother in law not to buy a 2013 Tahoe with cylinder deactivation. He got a good deal and bought it. I advised him to change the oil no later than 5K miles. He runs at least 300K miles. He’s at 135K miles now. There’re going to rack up miles in the next 6 months before retirement. He wants to move back to Texas or Oklahoma. He’s currently in Slidell. It’s going to get interesting.

Buffalo Trace.... I did the Bourbon trail a couple of years ago and fell in love with it.

Along with eating crow, I was given a GOLD Malibu as a loaner.

I have two brothers. One went with our clearing business when we sold it in 1999. He and his son run many crews clearing and making new ROWs mostly for oil companies. My brother has been easing his son into more responsibility so he can slow down. He says he’ll never retire completely. He doesn’t need to. My other brother is doing the same with the remaining equipment business. I went with that business. I chose a clean break at 58. I still go to the shop to stay up on the latest with equipment and my favorite subject trucks. I’m too OCD to be just partly involved. I didn’t even want to consult or train. I’m not very politically correct or woke. I call it as I see it. I can just hang out and amuse myself. Perfectly happy to do nothing. There’s so much to take in and enjoy. I’m a firm believer in retirement as soon as you can and pursue your hobbies. I worked so much building our business I still have catching up to do. You only have so much time before the body makes you slow down. That’s a fact.

I would love to see a UOA at the time of failure when the failure 'naturally". (60-80K). All I'd like to see is the GC fuel, 100C viscosity and add package. Not part of a normal UOA but a foam sequence and 150 C HTHS viscosity would be enlightening. There are nuts to crack in that bag.

That fits. It seems like 20-30k miles for the "bad batch" trucks and 60-80k for the rest. The AFM trucks all seemed to go at 130-150k. Anyone think we should start a data collection sticky thread where we all post our mileage-at-failure and drivetrain info to start logging this?

Mind me asking about your oil choice and regiment?

There was a straight up Bourbon yesterday for sure.

Got in just under the wire too... My warranty expires at 100,009 OR 5/24.... Literally 5 days from now.
