BREAKING: GM is officially recalling the L87

[undy]

I started watching the video and stopped it after the guy lost all credibility with me saying the 2018 Yukon Denali in the video had a L87 6.2L engine. Even us "lay-persons" that are familiar with this problem know a 2018 had/has a L86 in it. So much for this guy...

He explains that about midway through the video. Apologies for your short attention span

Additional News -- GM is helping to the tune of $50 per customer paid oil change, until they get the supply chain figured out for 0W-40 Oil. Your dealer should be applying this discount to any oil change invoices you have w/ 0W-40 until they stabilize the price. see attachment.

Potentially dumb question - how do I know if I received this discount or not? Just got an oil change yesterday at the dealer. My Tahoe got 0W-40 part number 19432866 at $12.63/quart. Dealer invoice doesn’t specify whether it was the supercar 0W-40 or the “new” cheaper 0W-40 that this bulletin talks about. However, based on the part number, it appears it was the supercar 0W-40.

Call your dealer - ask the service rep.

Interesting vid on the L87

0 weight oil on cold startups? But the sludge and shrapnel in that oil pan is really something. And I also notice the rod bearing clearances then checked were a bit over .002". That's old school clearance good with 10w40 oils back in the day. I ran 15w40 Rotella with that on the old small blocks.

On my oil changes it usually states that it's bulk oil, but that's standard 0w20 dexos.

Oh, that's cool. In the USA, they are following our path, and now they have reached the study of crankshaft hardness. The problem is that the hardness of the crankshafts of the L87, L84, L83, and L86 engines is exactly the same. Yes, the metal in the area of the connecting rod necks is not hardened, but it is the same hardness as it was, while the L86 drives without problems with such hardness, and the L87 is no longer there.

Off subject for the 6.2L but found another manufacturer Audi that is having multiple engine failures in their premium cars. Oil from he factory. 0-20W, on the Audi forum they are telling each other to switch to 5-30W or 5-40W for added protection.
Many owners have had engine failures. Cost of replacement engines is $30,000. Most seem to be in the 70,000 mile range at failure. It is not just GM pushing the EPA based MPG numbers with thin oils.
I was watching the Audi forum because my Porsche runs the same twin turbo engine and is subject to this possible failure. Years affected seem to be 2019 to 2025. Just an FYI, it is not just GM affected.

PS: I am aware that 0-20 oil did not cause the metal particles found in many 6.2L engines. That is a major cause of the failures, the oil weight is a separate issue.

Yet 10's, if not hundreds of millions of vehicles are out there running 0W20 or lighter oil for the last decade or more without any major issues....

It is not just GM pushing the EPA based MpG numbers with thin oils.

EVERY carmaker that sells ANY vehicle(s) in the continental U.S. is subject to CAFE MpG test scoring. Any oil 'thinner' than 5W30 exists to game the CAFE tests.

Stribeck curve ...
It's also true that in slightly subfreezing weather I can easily withstand up to an entire hour in nothing but a sweater jeans and flipflops,
so long as I get back inside before the hour's up, without suffering any PERMANENT issues. Just 'cause I CAN, does NOT mean I should have, ever.
(If I ever have any kids I will NEVER let them see me do it.)

Any engine that works or plays HARD, will be better off using 5w30 than anything thinner.
Engines that spec 0w20 in the continental U.S., spec 5w30 in most other countries.

I and many others willingly sacrifice 2MpG for better engine protection without hesitation.
If an engine fails to hit 200,000 miles SOMEBODY did SOMETHING WRONG.

ON THE OTHER HAND
IF ANY carmaker pinches pennies so hard, that their engines can only hit 150,000 miles with 0w40 / 5w40, that carmaker SHOULD lose customers' trust for decades.

I want to upset you)) but automakers all over the world do not live to pass this test in the United States)) for them, the US market is just one of the few, nothing more. And if 0-20 oil was used solely as part of the dough, then there would be a different specification in the U.S., and thicker oils would be available for the rest of the world. In fact, the 0-20 oil is normal, Volvo has been driving on it for more than 10 years, Honda if on liquid oil, Toyota generally switched to 0-16 oil, and this is not only for the USA, but for the whole world. My father has a Volvo V90cc, oil 0-20 with a mileage of 150 thousand miles, and he changes it according to the regulations, once every 13 thousand miles, and there are no problems at all, like other Volvo owners.

Does your Porsche call for 0w-20?

You want to upset, but you don't upset, you disappoint. Your translator needs upgrades. It has already misunderstood mistranslated me to you, and you to me.
Having said that ...
These other carmakers that are NOT GM are using tighter tolerances and clearances, so that 0W20 makes a little bit more sense for them, than for GM.
GM is still using Gen3 V8 tolerances and clearances on their Gen5 V8 while using 0W20.
If they had built their engines with better quality control, MAYBE they could get away with 0w20 like they did in the past, ok.
BUT
Clearly they tried to save too much money putting together the L87. Even 0w40 will not fix or protect mistakes as dumb as the L87 assembly errors.
There's literally swarf at the bottom of the oil pan. The proof of GM's penny pinching is literally sitting in the oil pan.

What I think he meant was that any vehicle sold here new must meet USA CAFE standards; regardless of where the manufacturer is based.

And also, that others have handled it better, Engine assembly wise. And it is proven that it CAN work in multiple world applications as well as in the US. So 0W-20 isn't "Poison".....

i cannot explain how a brand new engine has this much in the first drain.... GM is not cleaning... tooling shot... among other items.... it is terrible. i have seen it... 500 mile... yukon.

I’m surprised that the engine oil filter didn’t pick up more of what is visible in your photo.

What's sad is that all these engine blocks, etcetera should be power flushed. With filtered solvent. At high pressure. After machining. All passageways. Etcetera. They certainly know this. Somebody is asleep at the switch.
