The 6.2 has a upf filter equivalent. I just used tne Amazon link to show the picture.
Prove it.
What is you point, you CLEARLY DO NOT UNDERSTAND.
Are you data logging these other engines? How do you know anything about them ? These other engines make peake torque lower. Why would they rev higher in the same operational conditions as a 6.2?
How am I the troll when im literally posting data anyone can look up? With specs that are real and not fabricated in my garage?
"Support" is not the correct wording. "Prolong" is .. there... I fixed it for you.....
GM has never been guilty of poor quality control before? Seriously? What about the 10 speed transmission recall that you wrote ad nauseam about? That is poor quality control on top of a mainly poor design. There are two strikes right there on something that should go 100K miles min, without even having to look at it. Best transmissions out there today? ZF's hands down. Also, there's a big coolant control valve issue on 3.0 Duramax's because the valve's internals are made of crappy plastic gears. Another case of poor design, poor execution and testing and save money by going to the lowest unsupervised supplier.

Why is this ai now? What else should we say?
For the record I want the information we gain to be relevant. This is a discussion it isnt personal. We all want to figure this out to the best of our ability. I want the data we get to be meaningful and informative. So even if we dont agree we can still move the discussion along positively.
Fine with that, I appreciate that.
This is not true, the engines are constantly changing, and the crankshaft is different, and even the connecting rod liners are different
Id imagine the reason for the oil is because they need some delay. They probably deep down know that there wont be many engines in the recall list that get a clean inspection.
I've already posted the information here. We separate the two cases. 1. This is an engine failure when running up to 5-7 thousand miles, this is most likely a poor build quality and a violation of temperature gaps.2. This is a failure on a run of 30 thousand miles or more. That's what makes it more interesting and confusing. The L87 engine has different connecting rod liners than the L86. The crankshaft, connecting rods, everything is the same. The inserts are different, both basic and connecting rod. The L87 liners have more clearance than the L86 liners. Further, with mileage, this gap also increases with the production of the liner metal, and creating crankshaft production. After that, chips and metal dust appear, which clog the oil channels. and at one point, the engine finds itself in oil starvation conditions. Switching to 0-40 oil should improve the oil film at the Liner-Crankshaft point. And theoretically, this will lead to a further reduction in damage to the crankshaft and liners, but my personal opinion is that if the crankshaft has already started to damage, then changing the oil to 0-40 will just delay the engine failure a little bit, so as to complete the warranty. It is impossible to switch to 0-40 oil in a normally running L87 engine, when switching to an index 30 or 40 oil, the problem of lifters will most likely return as on the L86 (we already have such cars with a 5.3 engine with a mileage of 50 and 65 thousand miles, driven on 5-30 oil). The oil pump in the L87 is set to run on 0-20 oil, filling in thicker oil, and without changing the pump operation, it will cause the pump to pump as if the oil were 0-20.What to do? Yes, I have already heard on this forum that 99.9% will not do this, of course, on this forum it is more convenient to write comments on many thousands of words about suffering than to take the car to the workshop, where it will be given an inexpensive revision.It is necessary to remove the engine pan and look into it from below. if there is a crankshaft drain, it means an easy overhaul of the engine with replacement or grinding of the crankshaft, if there is no crankshaft drain, just change the liners to liners from L86, they fit more tightly, without having a gap like liners from L87, they will work perfectly on 0-20 oil. and they have a stronger coating than the gray liners from L87. having done this work early, you will most likely forget about the problem.
Yes Yes Yes! You get it!
The bottom end rotating assembly of these engines is virtually identical going back to the LS days. Journal sizes have not been changed. The first oil spec for a truck based LS was 5w30. This is found via a simple google search.

No 'support' is the right word. As in reaction forces developed in an eccentric rotor and hydrodynamic bearing system.
ahhh yes. There it is.
different part numbers but dimensions aren't.

no, the sizes of the liners are different, the liners from L86 sit tightly on the crankshaft, and the liner from L87 sits with a gap of 0.15 mm. He has more freedom. Plus, the L86 liner has a red coating similar to rubber, which does not wear off, and the L87 liner erases the coating immediately increasing the gap. I personally held them in my hands and compared them when they assembled my engine.different part numbers but dimensions aren't.

L86 6.2L EcoTec3 Engine Specs: Performance, Bore & Stroke, Cylinder Heads, Cam Specs & More - OnAllCylinders
The L86 is a Gen. 5, 6.2L, small-block engine powering 2014-present GM trucks and SUVs. They are known as the EcoTec3 6.2L engines. These engines use a longer intake runner than its …
2.559, 2.11 journal diameters, and stroke is 3.6. Same connecting rod length of 6.098. Same deck height 9.24.
These are the core dimensions in configuring the engine bearings.
They are the same.
Original oil was 5w30 for trucks.
CAFE also plays a role here.
Corvette and Camaro have 0w40 as a spec because their sales numbers are rounding error compared to trucks and suvs.
So they don't have to get 0w20 to juice up the cafe numbers.
