Lake Speed Jr video - Ignore Factory oil specifications!

[Sienna dude]

Another exciting and interesting Tribology video by LSJr.
Edit added to comply with site copywrite and media rules:
I like his closing statement about how a 0W20 in different geographic and climatic conditions will effectively be different viscosities over a very broad range. I.E. in Alaska in winter it will be very thick compared to in Australia in summer.
In my personal case this is why I run 5W, 10W and even 15W or 25W (case specific), because where I live it is so hot they still perform as thinner oils than say the above 0W20 Alaska winter example.
I also like that he adds credibility to using thicker oils than 0W20 to potentially increase engine life (again on a case by case basis). In my opinion the best way to reduce the environmental impact of motor vehicles is to extend their usable lifespan, delaying the need for replacement as the resources required for manufacture of new vehicles are far greater than running and maintenance - irregardless of any small fuel economy gains from 0W20 or thinner oils.

This doesn't apply Toyotas. Toyota motors never failed due to oil viscosity. I am enjoying 0w20 right now but will turn to my stash of 0w16 in fall.

 

[Sienna dude]

He claims at the end that GM is using this viscosity change as a "band-aid". I disagree. These engines, and many others, should never have been spec'd for 0W-20.

Toyota's 5.7L Tundra hit a million miles on 0w20 and it was hauling stuff all over the country. Oil cannot fix crappy design. GM's problem is not 0w20. Don't buy their junk until they fix the root cause

The summary of this video, which I am deriving from members here, is “Duh.” He is unwatchable to me.

Don’t we already know this?

Honestly, I do not get the Fan-boyism from members here saying it was “exciting” and we should “listen to him.” He didn’t say anything we don’t already know.

I’m with you @Pablo about this click bait clown. The only thing surprising here is the cult following he seems to have, even right here on BITOG. Baffling to me.

There are a lot more people that know very little to nothing about the information he shared. It’s a good video for people that don’t know, which is probably most people.

The Toyota 5.7l is a beast of an engine. The 3.4TT engine, relatively speaking, doesn't live up to expectations..

I would be curious to try a good 5w30 in a couple of those Twin Turbo engines and see if it helps..

 

[MrStamper]

Can you imagine if you had to link a current headshot of yourself here as your profile pic...lol. I can only imagine the motley crew of oil nerds we would see.

Guarantee you LSJr is 95% better looking (even with his flappy lip) than 95% of the Bitog regulars.

Thickies here are making me want to try the delicious nectar, 0w8, this fall

 

[Dyess]

As I said before significantly better than FordBossMe, RATBLOG, Scotty, Project Farmer, Eben etc. I'll take LSJ's videos any day of the week over the other clowns.

He's also provided shear stability #'s for many Mobil 1 grades, using HPL's lab no less, and even got the inside scoop on VRP. Not sure why so many don't like him.

Eben is the absolute worst, I can’t stand his nonsense. “Better than brand new” gtfoh

Go for it. In the LSJ video he said during testing for GM, they had to reduce viscosity to increase bearing wear.

Thin around and find out.

Toyota's 3.4TT had some manufacturing defects, it has nothing to do with oil. They are giving new motors to folks. Toyota motors have had issues in the past too, none were related to oil viscosity.

My car is Toyota, not GM LSJ is gladly running 0w8 in his daughter's Toyota Corolla. He says her daughter intends to drive the thing till its wheels fall off

 

[MuzzleFlash40]

Has anyone here ever been denied a warranty claim from the manufacturer due to using an oil viscosity not listed in the owners manual?

Both of our daily drivers spec 20 weights 5.7 Hemi and 3.6 Pentastar. I’ve been kicking around the idea of using 5w30 in both. I know there are plenty of high mileage examples that have used 20 weights. But there’s no downside to using 5w30 either. My only concern is they are both still under warranty. Guessing it’s probably better safe than sorry to just wait until their warranty ends. Which isn’t too much longer.

 

[Danno]

Is this factually true? Loss of brain power?

Boeing would like to present itself as a case study on loss of brain power and the consequences.
Wouldn't be a stretch to say same is happening to many industries.

 

[4WD]

If you never got stung by design carelessness, yeah, it's not relevant and your sarcasm hits a mark.
If you're among the many who have been, you now have a new generation of company.

You bring up Vega - I think that’s not relevant …
(and I’m doing fine with GM) …
Then I get a warning …

Toyota isn’t perfect either. Their twin turbo V6 has suffered from early failures and a recall too.

Just as there is no advantage to a thinner oil either, except a marginal improvement in fuel economy. They aren't "better" for the engine. Increased HT/HS always reduces wear and in so many applications where fuel dilution is an issue it is entirely beneficial.

The use of the word "nectar" as you state is silly. It's not nectar. The engines have been designed to tolerate such oils under most circumstances without excessive wear. But it isn't as if it's a nectar to the engine.

 

[dnewton3]

Let's remember that the Toyota 3.4L TT in the Tundra, etc is built in the States.
But that same basic design was introduced in the LS500 in 2017 or so, IIRC. That LS engine is built in Japan, I believe.

So the same basic design survived several years on 0w-20 with no issues. The "problem" came from some change, challenge or process that was unique to the manufacturing in a different facility here. It had zilch to do with the viscosity of the lube.

PF's a clown. His oil tests have no technical merit whatsoever.

Project Farm is the best product review site on you tube. His oil testing segments are weak, I'll admit that, but they are also make up a very small part of the overall content. Hard to believe anyone who has watched his channel for any length of time calling him a "clown".

 

[OVERKILL]

This doesn't apply Toyotas. Toyota motors never failed due to oil viscosity. I am enjoying 0w20 right now but will turn to my stash of 0w16 in fall.

Toyota has had bore scoring, ring coking and oil consumption/engine failure due to their combination of poor oil drainback designs, lack of an iOLM and high volatility OE oil (TGMO). There are places other than bearings where oil selection plays a role. The old Car Care Nut has tons of Toyota tear-down videos that have shown some of this stuff.

 

[Hohn]

Debatable. Not yet proven. Speculation.

That said, so by saying that, he knowingly titles his threads with click-r-bate words. Some shreds of respect for the guy are wearing thin.

I'm trying to separate style from substance but I'm finding the style harder to get past to get to what is often quite good substance.

 

[gfh77665]

Problem being is that often his “data” is worthless, and subsequently so are the conclusions.

And that's just your personal "conclusion" on PF. Nothing more.
