While this is true... I hardly ever visit a form/subforum of a vehicle/MY I don't own. I've never really looked at ANY threads pre 2021 on here.... Without owning one, my perspective and experiences just don't logically transfer to that era unless we're talking about very generic auto related things that would apply to most any vehicle....
Does the company that did this analysis have a fleet average in their database for that engine?
Here, everything is very simple. Owners of old cars really want to amuse their vanity, and once again emphasize that they have an old car, not because they can't buy a new one, but because it is very reliable. But we know that this is not so. And such things should be treated indulgently
I recently took a ride in a Tahoe 900... oh... how much progress has come))
That is your opinion, so stick with it.
It's not going to last on 0W20. The bearing clearances between the old LS engines and the LT engines is the same as far as I can tell. My old, wore out, 5W30 oil has more viscosity in it than yours does new. My engine is humming along at 200K plus miles with excellent oil sample reports.
Exactly. I have gathered sooo much valuable info from other members, often on topics I was not even looking for. Jerry455 sounds a little agitated that someone dares to post something about a vehicle that is not specific to this sub topic. He might have a better day if he just moves along and skips posts that dont have information he is interested in.
And some of use own more than one vehicle, with vehicles spanning decades. At one point I owned vehicles that spanned 1971 to 2020. And not long ago I owned A gen 2, 2 gen 3's, and a 5th. As a result, some of us are all over these forums.Here, everything is very simple.

You write unsubstantiated nonsense. 4th generation engines drive well for many hundreds of thousands of miles on 0-20 oil
I change my oil every 3,000 miles. With synthetic oil.
You can change every 1000 miles, but why?
Alright Vladimir, keep posting those oil samples to 200K miles or more. I reckon you see no problem with those viscosity numbers. To each, his own.
What exactly caused you bewilderment in my posts?
That is why this Forum is so much different, and BETTER, than most other Forums. Folks here recognize the advantages of not being pigeonholed into only one box with blinders on. The act of sharing and learning new information makes us all more informed and better able to care for our trucks, regardless of the model year and style generation. It also builds a much broader Community for all members and fosters genuine discussion and collaboration.
Industry wide it’s well known 20weight is for mpg, not longevity. You defend 20 like it’s the holy grail. I almost forgot, your long oil change cycles. Yes, these positions puzzle me.
In what industry?) Who knows? Experts on forums? Are there any real studies confirming that 0-20 oil leads to a decrease in engine life? Are there any real studies that more frequent oil changes increase the life of the engine? Real research, not phrases from the series I do this, and my engine runs for a long time. And I drive on 0-20, already the second generation of GM, and my previous Chevrolet Tahoe with a 6.2 engine drove 100,000 miles without problems on 0-20 oil, which I also changed according to the regulations once every 7500 miles, driving on it just as hard with the pedal to the floor and driving on the highways at high speed. There are no such studies, so no industry knows about it, and it remains just words from the forums.
