If my warranty is voided so be it. Realistically Magnuson Moss act probably protects you.

Yeah. If you are out of the recall and your engine goes kaput, I would think Lexus could argue it may have been because of the "out of spec" oil, but I think they would have to show evidence of this link if you bring them to court. On top of lawyers, experts would be involved, and bills would quickly become astronomical.
Oh boy he is saying stick with ow20.
Interesting. He is pointing to the 0W-8 oil, technically. He also suggests that it might be fine to have oil that's marginally more viscous (the bottle adjacent to the one your car says to use), so still think it could be fine for 5w-30....maybe...?
Yes i saw he didnt technically point to 0w20 but the inference basically he is pointing out is to stick with manufacturer oil recommendations.
I think it's to avoid legal issue. If he's advising people on what oil to use and per Lexus, it's not the recommended weight. Even for his shop, he would need to follow the recommended weight because if s***s hits the fan, he could take blame for it.
He's a shop owner first and creator second. If the owner of car said hey use 5w30 on mine, I'm pretty sure he'll do it. He just won't recommend it because he can get sued if something goes wrong.

We need to get comfortable with the fact that we will never have a credible confirmation that 5w/30 is 100% OK on US spec vehicles. Nor will we ever get 100% confirmation that it’s not.
The video does bring up an interesting point on programming of the oil pump which is certainly worth incorporating into your preference between factory recommended and 5w/30. We had a cold snap up here in New England and I’m running 5w/30. Did have very high readings on oil pressure until engine reached operating temp. This may be identical in 0w30 but I don’t know.
As for viscosity vs design…..spoke with some folks who are more “in the know” than most.
Likely design. Exact causal factor unknown. Timeframe for long term change unknown.
I’m just going to drive and enjoy this rig with confidence knowing that the answer will come and Lexus will stand by it’s product.
I’ll also be switching back to factory recommended just to avoid any potential negative impact on qualification for replacement later reinforced by the knowledge that it’s not viscosity causing the failures.

Great insight.
Thanks.

The pump is 100% mechanical. It is chain driven off the crankshaft. This is directly from Toyota.
(a) The oil pump is combined with the timing chain cover assembly and operated by the chain.
(b) This oil pump uses an internal relief method which circulates relief oil to the suction passage of the oil pump. This aims to minimize oil level change in the oil pan sub-assembly, reduce friction, and reduce the air mixing rate in the oil.
(c) An oil pump rotor with a high efficiency shape is used. The oil pump rotor diameter is decreased in order to reduce friction.

Correct. The 3UR has tighter oil clearances than the V35A.
Here is what I posted on lexusclub (kinda dead over there). Some more of my thoughts.
I think they are asking too much for fuel economy Koolaid.
0w-20 oil with viscosity @ 100c cSt of 8.5 and 120hp per liter. Then very importantly stupid, add in programming that keeps it in a higher gear almost constantly when needing to accelerate, which exponentially increases load/boost/cylinder pressure (that eats bearings). Create those conditions at low rpm and you have a perfect storm of bearing destruction (research Stribeck Curve).
They possibly try to offset the wear by keeping it in too low of a gear with the converter locked while coasting. Basically little boost needed, this causes it to bump and rock. But you cant ‘offset’ bearing damage. Although this could be for fuel economy.
Oh then add in Auto stop/start and very low rpm idle.
Go woke, go broke.

Kudos to Joe for being one of first to bring up the oil issue. I dont recall reading anyone else mentioning oil issues in beginning.
Very good video

Yes nice he must be reading my comments on past videos.
I need to pull up the texts I sent the dealer at 16miles and screen shoot them for yall. Definitely a hydraulic or oiling issue present.
I think they need to include any vehicle in the recall up till they revised the 26 manual. You can’t just reverse bearing damage.
