and second place is just the first looser - credit to the late, great Dale Earnhardt.Remember: A tie is as good as a loss, and no one remembers second place.
GM aborting move to 0w-40
- Thread starter dbias
- Start date
Well, they were running out of 0w40 oils anyways…
GM got some bad parts- hence the bad engines. Going to cost them dearly. But at least I give credit for doing the right thing.
Sad part is, this won’t be the only issue they deal with concerning these trucks and SUVs……

GM has a long history of knowing they have a defective part, but deciding to use them in their cars anyway. The most recent that I can think of was the ignition switch fiasco. No, wait. Takata airbags. Then ignition switch. At least this latest one isn't resulting in lost lives.
Let’s be fair here, not just GM.
19 automobile makers, 34 brands
67 million airbags
And Honda brand was the most serious issue of all of them, the models below are labeled do not drive and they are not General Motors cars.
“Models flagged as being at an extreme risk are certain 2001 to 2003 Honda and Acura models containing so-called “alpha” airbags, and the 2006 Ford Ranger and Mazda B-Series pickup trucks. Also included are the 1999 BMW 323i and 328i.” NHTSA advises that owners not drive these vehicles and seek immediate repairs.

Agreed. But it isn't just the Takata airbags. I'm struggling to recall, but I know there was another similar issue before the ignition switch.
I’m not saying they haven’t had their issues
But most brands do have failures for certain models and being general motors sells more cars than anyone else in the country. Of course it’s gonna get more attention.
I’m not sticking up for them. It’s just that I have had a number of foreign cars from Honda, Subaru and Nissan and they all let me down in one way or another, some serious and costly
With the GM cars which I am now back to. In many decades I never had a major failure, sure the hardware might fall apart, but that’s minor stuff.
Of course I do agree 100% the V8 issue is huge and probably heartbreaking for many people.
If I had one of those V8 vehicles even if General Motors told me my particular engine was OK I wouldn’t trust it unless they were going to give me a extended warranty or something

This ...
I mentioned it a week or so ago in another thread.
The engine is certified with the 0w-20 for fuel economy purposes. If they didn't do all the tests to validate the 0w-40, I'm sure all Hades is breaking loose in terms of legal entanglements.
Not to mention that in this circumstance, it's a band-aid that's not gonna stop the hemorrhaging of metals anyway ...
NOTE: I didn't watch the full video, but at min 13:30, it specifically states and shows that 0w-20 is now the correct oil in the newly replaced engines. 0w-40 is no longer the recommended lube.

Wasn't that always the case? If the engine didn't have the code, you were to switch it to 0W-40, but if it did have a code, it got a new engine, and the new engine was still spec'd for 0W-20.
Correct. 40wt if it passed, new engine and same old 20wt if it was replaced. What a cluster for folks buying these on the used market.
I’m sure it wasn’t his idea, but it sure could have been… the bumper sticker that said “If you want to come in 2nd, follow me!”
Millions of vehicle been using 0W-20 for 20 yrs +- and its not been problem. My brother and I both had 2021 Sierra;s with 6.2L and no problems. I traded mine away last fall for a diesel and he traded this past Fed for another Sierra 6.2L.
I read the issue with 6.2L is from defective parts (crankshaft) from outside supplier.

... or the engine damage. Maybe GM will spec out using 20W-50 from now on.
I agree. One thing that does come to mind regarding the 0W20 oil, the 0W40 could very well be a better choice. However they might have had to stick with the 0w20 because of time constraints as you mentiond on all the testing and validations, along with the vanishing CAFE credits from bumping the two grades. Lose, lose for GM, and I'm sure they're smart enough to know when and how to cut their losses. If I owned one of the vehicles in question, I'd be dumping the 0W20 and filling the sump with 0W40 as soon as possible. GM's Band-Aid move already tells me 0W40 will work fine in that engine.
If anyone actually gets a new engine from this please chime in. Hopefully it won’t be another brother-in-law’s uncle story.
Sad!
First Toyota now GM! What's going on with the engineering and/or manufacturing of new engines?

What bearings would those be?
Likely nothing wrong with either engine.
It was the mass implementation of the 20wt experiment. 10cSt at peak operating temperature has always been the correct way.
