The Truth about 0w20 vs 5w30 YouTube

I’m running 0W20 OEM in one only - I spike it with EC30 and come summer I change it to 5W30 via a Fumoto - and leave the dealers filter (they are numbered). Paid dearly for an extended warranty.
So, yeah - not a big 0W20 fan. The 2017 ran Mobil 1 0W20 for 60k - and after EC30 and Valvoline Restore and Protect - all I did was toss allot of pristine filters …
AI will ruin any credibility YouTube ever had ...
The GM L87 recall taught me one thing. The correct oil viscosity depends on the machining of the engine components. I think it's also depends on the age/wear which increases tolerances. You can't say one viscosity is always better than the other. The truth is it depends.
Good old tolerances that dictate/require an oil grade.
Take a single kernel of something close to truthish and grow an entire forest of weak trees of balsa.

That’s worth allot of cash!
Wait….. what!?
I have run all but about 15k miles(ow20) on my 2018 Tacoma with 95k with 5w30!or 0w40 in my 2018 v6 Toyota Tacoma. In the next week or so I will start running g valvoline restore and protect 0w20 in it. If I run it in the summer down the beach in 4x4 or tow hard with it I will go back to 5w30 or 0w40 or even 15w40 depending most likely bro 5w30 though I don’t consummate but want to do some passive maintenance.
I'm watching LSj's response to the Big Oil Secret video right now. He really comes down hard on it, as not only totally fake Ai lies, but absolutely destroys any conclusion that 5W-30 protects an engine better than 0W-20. At least in gas engines. His words, "100% fake news".
I seem to recall him saying it was engine/conditions dependent. He’s made recommendations to customers using his UOA service going both ways. No statistical difference in 129 used oil analysis with engines over 10k miles.
The wear studies I’ve read don’t use used oil analysis to measure wear. I believe used oil analysis are limited when comparing oils and not the best tool for the job.

That's a good point, one that Lake has also made in other videos. So it is interesting that in this video, he relied pretty heavily on UOA results to make his point. Could it be that comparing UOA between the two types of oil, while not the whole story, does give a usable comparison of engine wear, and thus how well the oil protects the engine.
Yeah, what I actually took away from Lake's video is that 0W20 can potentially be just as good, IF oil change intervals are kept short and the oil isn't allowed to shear out of grade. If you're doing 10k intervals 5W30 is still the safer bet.
In any case, these AI videos are out of control. I saw a stolen clip from one of my own videos in one of these AI videos!

Sadly on most any subject YT is turning into an AI sinkhole. Very unfortunate.
The truth about 0W-20 and 5W-20 oils bought at Walmart (or any OTC store) is that you better change them at 3,000 miles than 5,000, if you want good results.

I disagree. Under the right conditions there are a few 20 grade oils sold at Walmart that can go way more than 3-5k. Pennzoil Ultra Platinum, Mobil 1 ESP, Extended Performance and likely the new Advanced Clean too. Castrol EDGE Extended Performance can handle longer intervals too. In a port injected highway driven car like my Civic, it would be a total waste of money to change the oil every 3-5k. I prefer 9-10k (I drive 25k a year)
Those are exceptions. A hand full of oils that may do well at over 5,000 miles.
ESP and Edge are new oils that were not available in the US several years ago. And Advanced Clean came up a couple of months ago.
