Recommend an oil for GX550

How do you mean? I bet covering your back will make it harder to actually deny work or make it complicated.
I mean, whatever, not my problem. But there is A LOT of wishful thinking among folks owning this engine.

I don't own the engine and have no dog in the fight. I just fundamentally reject the idea that one should walk on eggshells begging and pleading for the warranty coverage you are rightly entitled to. It's one thing to deny warranty because someone modified a vehicle-- like these guys having warranty vehicles "tuned" and then when they blow their engines, the scramble to take it back to "stock" so they can defraud the OEM and claim warranty for their tuned engine that failed.


That's entirely different than having to prove every maintenance was done by only authorized persons using whatever oil in order to have warranty cover a known and well-publicized product issue.

Frankly I have more experience and skill than any young flunky who happens to be pulling oil change duties at the dealership. (You and I both know that ASE master techs aren't getting paid premium hourly wages to change oil; it's the least experienced, least qualified kid in the whole place who gets oil change duties).

And I doubt that the Toyota that swapped FRAMES out on Tacomas is going to not stand behind their TT V6 engines and the debris issue that has been documented.
 
I’d use a stout 0w-20 at 5K intervals between dealer oil changes, video the oil change with Toyota filter, and I’d go to the dealer every 10k given the known issue with the 3.4L Toyota engine. Another option is to pour your 5w-30 into your emptied 0w-20 jug during the video. ;) It annoys the hell out of me that these crooked companies give any excuse to deny coverage. The politicians should attach a stiff fine to any violation of the Magnusson-Moss act. But I personally would avoid have avoided buying that car for another 2 years until it is clear that the engine issue has been resolved. Only time will tell this.

Recommends but not required right? If you're not comfortable with 0w20 then just go with
5w30. They'd be hard pressed to prove which
grade is in the crankcase. Enjoy!

They'd ask for receipts showing what oil you bought/used. Some dealers may still give a hard time. Toyota is known for being difficult with warranty. I'd do a 1000 mile oil change at home then have them do every oil change from there.

SOME dealers will let you bring your own oil and have them do it and still count as protecting your butt. This is my plan for my wifes kia seltos. Some will even let you use a slightly thicker viscosity.

Those eggshells start at $63,000 and easily go over $100,000.

I don't think they care about your experience and skill. Considering the issues people have with Toyota dealerships, I would be hesitant to give them any excuse.

They swapped frames bcs. it was impossible to hide it. Remember, in 2017, they left owners of HL and Sequoia AWD in limbo over issues on 8speed. This is the same company that refuses warranties on Corolla GR if it was driven above 85mph or denies any warranty on GR86 over failed rod bearings if driven aggressively, although it is marketed as a track vehicle.
This is not a debris issue. This is a design issue. They claim they resolved problems, yet engines are still failing (among other things).
 
This is a design flaw no matter what Toyota claims. This will make itself clear as engines on 2024 and 2025 model years continue to fail. Or hopefully not.

It is clear that some 2024 and 2025 model years have failed. And yet Toyota has not yet expanded its recall. It is also clear that 2022-2023 Hybrids with the same engine have failed, but Toyota calling it a safety recall has not recalled the hybrid versions as you could potentially limp to safety on electric power. Time will tell how bad the issue is on the newer cars.

Should we trust Toyota?

Expsensive and not readily available. Plus I have doubts about it being any better than Mobil 1. ExxonMobil also makes base stocks so they have more cred.

Amsoil is readily available. If you can log onto BITOG and make the bolded mindless statement above, you just might be able to log onto the Amsoil website and place an order.

It's up to the mfg.to prove that the oil you used was the cause of the problem. Recommend vs required means that you are not bound to use that specific grade of oil.

Yea. Legal fees to fight it will cost more than an engine

If the sump oil is clean and full that's all the consumer needs plus a receipt I'd imagine.
Comes down to recommended not required.

While I agree, you could have dark oil half way through an OCI. I do my own OCI, and keep receipts and a physical log and a log in MYSUBARU app and carfax app.

I think that should suffice. But people quote M and M like it's infallible.

Yes, they have to prove you created an issue. But you have to sue for it to get to that point. And car manufacturers have more money than people do.

I don't believe it even gets that far. If the client has a cut and dried case it's not that complicated. The adjudicators are usually going to side with the little guy if he or she has a solid case. Cheers...

My GX550 is arriving very soon. I will be driving it to explore our beautiful country and it will be towing 6000 lbs(another vehicle, a Jeep TJ) and hauling around 800 lbs throughtout the journey. So it will be working very hard. Manual recommends 0w20 but I don't know if I can trust that. Nothing crazy, I just need something a little more shear proof as these turbo motors run hot. Thanks in advance!

I have this engine in my Tacoma. It does not run "hot". It actually runs cooler than the engine in my civic, both in coolant and oil temp.
