I asked Lexus and Toyota but they don't offer any discounts same thing with filters. Motul is pretty cheap at lordco at $48 for 4L (~$12/L), but im wondering if it's worth it cheaping out over the TGMO which has a pretty crazy additive package.
MOTUL HYBRID 0W-8 VOA or UOA?

I’ve been here a long time and have learned that there’s more than one means to an end when it comes to engine oil. I am absolutely not qualified to say if the Mobil 1 I’m going to use in my wife’s Corolla or Motul or Eneos is better or worse than TGMO just because TGMO has a “crazy additive package” that includes 800 ppm of moly (the type of which we don’t even know). I tend to think that Mobil 1 is ahead of the curve so I like to use it. Particularly when we really have no clue about the composition of the total package or the ability to interpret what it means.
Yeah it would just be nice to have more data is all. I might swing it and go for motul.
No, again its still the same combustion engine. ONLY EPA EMISSIONS CAFE whatever that regulates GLV-1 in USA and by extension Canada since source from Toyota corp. US. There is no technical changes/reasoning behind the restrictive oil choice/mandate.

I don't know where you got the spec sheet for the "2024 ux 300h" from, but it's completely wrong. Because the ux300h didn't exist until the 2025 model year...
Regardless oil specifications are explicitly changed in the owners manual, and even if engines were 100% IDENTICAL, it wouldn't matter because Toyota/Lexus specced 0W-8 and if you didn't use it they can legally void warranty. Try to argue with the engineers in court, they have actual data and part numbers to back up their claim, you have nothing to go on besides saying it's the same motor - and you don't even have comparison to how wear varies from oil to oil.
Not sure why you keep thinking you can outsmart the warranty situation, it's clearly written the car needs 0w-8 with jaso glv-1 requirements. So 0w-20 is out of the picture and 0w-16 is temporary at best. Any skilled lawyer would run circles around the counter examples you have posted, and all they would need is that one line from the owners manual stating you have to run 0w-8 and if you use 0w-16 you must replace it with 0w-8 at the next oil change.

Hmm yeah they show 250h figures for it.
4 EPA-estimated 43city/41hwy/42comb MPG rating for 2024 Lexus UX 250h FWD. Use for comparison purposes only. Your mileage will vary for many reasons, including your vehicle’s condition and how/where you drive. See www.fueleconomy.gov
Toyota US Corp not Toyota.
Not sure why you're using a dealers website which more often than not gets stuff wrong. Use data directly from the source aka lexus.ca or lexus.com. and you'll see the ux300h is brand new for 2025 and never existed before hand. The ux250h is also down 15-16 HP and a lot of torque.
Also when you're disputing warranty in court, pretty much what you're trying to argue is: "I know your engines better than you do Toyota, and therefore I can do whatever I want and if something goes wrong you still have to pay for it." Yeah no judge or jury will ever buy that, and you wouldn't be able to prove this vs. the mountains of testing data Toyota has. Despite that you do realize warranty is only there to effectively have Toyota put their money where their mouth is, I.e. back their own engineering decisions. "For example Toyota is effectively saying trust me 0w-8 is fine, and if it isn't don't worry about it I'll fix it for free". That is moot when you start fumbling around with different oil weights, and Toyota no longer has to back their reliability claims.
I don't care about your warranty. Its about you believing there is a reason beyond EPA/Toyota US for the specified oil in North America.
There isn't one.
Japanese ux300h manual.

You do realize I understand the reason why oils are getting thinner is for fuel economy/ emissions standards right? And it also helps hybrid activity where the engine stops for extended periods of time and has to immediately restart, you do realize a 30 and 40 weight can't tolerate that right? Imagine that occuring when it's -30C out and your 40 weight oil has to immediately flow and hit 5000 rpm, yeah that's definitely going to work out real well
But the whole point of my thread is picking an oil that still conforms to warranty requirements - something that actually matters to people with new cars, that's the only issue here that you don't seem to understand. You're the one coming in saying don't use 0w-8 just use any random crap and then throwing random irrelevant data from different countries and different cars that don't even help. The fact you keep circling back over and over with different arguments proves you really don't understand the entire point of this thread, and you are the actual one that is confused here.
Btw post the rest of that Japanese owners manual - because you seem to be very good at pull quoting to prove your point but leave out critical details or just out right post misinformation ( as you did with the "2024 ux300h" from some random dealer ship), im thinking they're using those 0w-16 symbols to show what API approved logos look like. But if you translate the portion talking about oil change intervals they're likely going to specify 0w-8 just like north America.
Rest of world has same warranty with table shown above. Stop talking mumbo jumbo.
You do realize the table is comparing operating temperatures of weights right? But the stipulation of oil choice is in the text?
Like I said before that is out of the scope of my thread - because I need warranty complaint oil for my car.
Use 0W8, never said you could not.
Any 0W will be fine for cold climate. If its -30'C the engine will be running 100% to heat the cabin.
As much worries with warranty issues as he has dealer service is the best bet. Dealer just gonna be using 16 or 20 grade anyway is my guess.
Thats what happens here (sometimes) and some customers will get mad that they don't use 0W8
No they do not. If you use a grade that causes damage then yes. No oil with a higher grade will cause damage, not from the grade alone. HT/HS protects, not the other way around.
But if you cannot understand that or are still fearful then use what the manual recommends.
No they cannot “legally void warranty. You have no evidence to support that claim. It simply isn’t true.

At the end of the day if you’re really super worried about any possible warranty issues then just get all of the oil changes done at the dealership until the warranty is up.
There’s a lot of misinformation here. First off warranty disputes go through arbitration at no cost to the customer. The dealer will have to convince arbitrators that your engine failure was oil related(which they won’t be able to). Oil related failures are beyond extremely rare. Neglect is the most common customer related cause of failure(simple pictures of clean engine internals will prove oil changes were done). Bad design is by far the leading failure of engines under warranty. Another misconception is a uoa on a catastrophic failure will show anything about the oil. Having been part of warranty disputes in the past, arbitrators rarely side with the dealer even when right. We lost to a customer who destroyed a transmission in a s10 blazer towing way over the limit.
