I do the same thing to dilute the residual old oil in the pan. I can actually watch it turn from dark to light as the "flush" quart drains out.I'm sure this guy (Lake Speed Jr) is more intelligent than I am regarding many things. With that said, I watched one of his videos, and he poured a new quart of oil into the engine to flush the oil pan after draining the used oil out. I checked out and never went back.
I agree. PF is a singular version of the "user reviews" you see with many products, hotels, vehicles, etc. No "user review" or "customer review" has to be rigidly technical. I very much like these, and I trust them more than an "expert review" I might read. I am not implying the experts are wrong, but clearly PF is unbiased and he clearly is not sponsored by anyone.
“It’s not scientific!”
Yeah but that'a not due to oil viscosity
So your professional opinion is that the use of 2 to 3cSt base oils plays no role in any of these phenomena?
No it isn't. The "tests" he uses for motor oil are not for motor oil, are not performed in accordance with the proper test procedure, do not use the proper equipment and the results are not analyzed properly. They are equivalent to using any test that does not apply to any other product. Sort of like using a water quality test on a heart medication, it does not apply as it does not measure a relevant and meaningful property.
I don't think that is the correct way to look at it. Lake Speed's video clearly goes into the design, manufacturing and production issues that result in imperfect wear surfaces, which in turn result in friction. In the Government Motors, EV, DEI world, that may well have been inevitable. I could rant endlessly about the unreliability of GM products and their focus on EV's, refusal to build cars (which presents no challenge for Honda, Toyota, BMW, MB, Audi, Tesla, Lucid). The fact is that GM has lost their own plans on building V8 American Engines that would last hundreds of thousands of miles. Changing the oil spec and oil cap might be a good stopgap for GM, but is far from being a solution to the poor operational execution of the design and production of this engine.
That’s not true- that is a generalized twist
Is it a mechanical problem if my LT1 has bearing problems on 0W-8?
Is that is what is going on here?
None of that is. It seems like folks don't listen to the video and create new talking points.
He uses the same "seat of the pants, garage benchtop" methodology for everything just the same. He is what he is, and he does not hide it, in fact he openly discloses it. That's exactly why I like the guy.
Ok full circle. Read the video title
Which may be fine for knives and hammers. The dude is out of his league when using his tests for motor oil.
You already said you didn't even watch it.
Then feel free to ignore him, just like I ignore the paid shills some people trust on YT.
They did, but as do the other automakers the problem of damage comes in by using an oil with too little HT/HS or with perhaps something such as an improper ash level. This warning is appropriate but it makes it sound as though a -30 or -40 grade would cause the damage, which is incorrect.
Maybe a few, a whole lot probably not. Sounds like the perception of people trying to start a YT channel.
