2024 Tundra engine OCI plan

[Japanese]

They have been failing since 2018. Main bearings were failing in the LS600 when the engine was introduced in 2018.

"The cause of the recall was machining debris left in the engines during the production process, which was not a fundamental issue with the engine design. This debris can damage the engine crankshaft bearings, causing problems with the engine."

I just read that, not sure how accurate is. Often the publicly announced issue doesn't have anything to do with the real issue. It could be the material of the crankshaft bearings.

Yeah, I know what they have been saying.

Our local dealership uses Valvoline. Actually, Valvoline flag across whole garage wall.

His main reason is to change the oil every 5,000 miled, not 10K as per OEM manual. He probably chose Amsoil because the car brand new and is a bi-turbo.

The official version of why those engines fail is that some kind of debris (possibly metal shavings) were left inside the engine from the factory. But the random mileage failings tell me it might be something else than just metal debris that are easily caught by the oil filter.

Plus I’ve been using Amsoil about 90% of the time in all my vehicles since 2004.

So if you’re gonna run AMSOIL, what oil is the dealer gonna put in it?

probably some cheap Mobil crap or worse, as my dealer said they use oem oil, and found out its some low-end bulk Mobil, makes you wonder why the high prices they charge, for that you better off doing it yourself using Amsoil for same cost.

What my BiL did 400k with - Mobil super semi in bulk
Jobber filters …

Mobil 1 ESP 0w30 for 5k and dealer bulk for the next 5k if you wanna do it that way save the AMSOIL money for other vehicles

What does your invoice say?

When my cars are at the dealer for ToyotaCare maintenance, the invoice lists "002790W20101 - GTMO 0W20 BK SP WTY"

Just an FYI, they call any oil meeting API spec "GTMO" so I'm pretty sure you're getting bulk oil. FWIW.

I thought about that but wasn’t sure if going back forth between bulk and European speced oil would cause issues. Since I’m siphoning out the bulk oil it wouldn’t be an issue.

I saw a new Tundra yesterday with temp tags towing a massive boat...
I hope he changed out the factory fill...

If there are towing restrictions when new-it's in the owner's manual. Of course-you have to read it.......

Unfortunately most owners manuals lack common sense these days. Or maybe owners are lacking common sense…I guess that’s asking too much from the OEM. Probably doesn’t restrict track days or off roading during break in either. There was a time when detailed break in instructions were in the manual.

Most Euro oils also have an API license. Even if they didn’t you’re not going to cause an issue.

I know towing restrictions when new are probably in there. But you can't cover every instance when an owner will be an idiot. Like taking your new truck to track days. If you feel they should publish that and other absurd things-then we respectfully disagree.

It use to simply say keep engine at light load, fluctuate rpm, no prolonged high speed etc. to cover no severe service during break in. I’d hope most people would know this…but some don’t see it in the manual so they believe they’re good to go.

What is TGMO?

Guess..... Toyota Gas Motor Oil

There should be a sticky thread for acronyms for newbies.

Too many apostrophes.
