2024 Tundra engine OCI plan

[tired]

instead of wasting TGMO, just ran it for the first 3000 miles and replace with your boutique oil for the remaining 7000 miles.
rinse and repeat

They're not putting TGMO in. It's cheapest bulk swill they can find.

Going forward on my 24 Tundra. I’m going to siphon out dealer bulk oil for AMSOIL Signature Series 0w20. Granted it will be changed every 5K. The dealer will do the 10K per my maintenance plan up to 85K. I’ll do the 5K change. Both times the filter will be changed. After the 85K I’ll do a used oil analysis to see if it could be pushed further.

I would cancel the plan but it gives me documentation for warranty purposes till my 75K warranty is up.

I don't think the plan offers you anything extra above keeping the receipts from Amsoil, which will be easy because it's logged on their website and you will have emails.

I'd cancel the plan and get my money back if you're willing to do your own oil changes and just save receipts. You just need documentation of oil changes.

I’ve also been told it’s what ever oil they have in their barrels…not TGMO. Even then paperwork says bulk oil.

 

[ARB1977]

so you're only putting 5,000 miles on the Amsoil? not calling you nuts.. but why waste money.. are you also using the oem filter to keep the toyota warlocks happy?

Yes

This or even 2-3K

Is there a link about these engines failing randomly?

I did my first change at 1700 miles then 5000 miles…5K after that. Currently at 20K. Fingers crossed I’m one of the lucky ones.

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

 

[ARB1977]

Yes you’re nuts. You must use AMSOIL Signature Series 5w30.

It’ll be SS 0W20.

If you have a 2024, I don't think you're affected by the recall. Hopefully they have the issue sorted out.

I hate the idea of being forced to use the dealer to change oil for fear of being denied warranty coverage. I'd keep detailed records, save invoices for oil and filter purchases, and document my oil changes, then skip the dealership altogether. I did just that with both my Jeeps, one of which had two years of free oil changes and a lifetime of free NYS inspections. I told the dealer my plans and both Jeeps are still alive and well long after the warranty ran out on them. Having said that do what makes you sleep best.

 

[Wireman1987]

Yes

I don’t think the amsoil in 5k oci’s will stop or prevent an issue if it’s going to happen. You’re wasting money personally. That’s my 2 cents of crypto.

 

[Hohn]

Well, you are on BITOG, the odds of being a least a little nuts are elevated. We prefer to think of the less oil-obsessed as the crazy ones, though.

If it's a new engine then proper break in is important and helps set engine for rest of its life. I think first couple of OCIs are critical.

In a modern engine, the break in is mostly complete the first OCI and the last 10% or so is what you see in the wear metals up to 15k miles or so. So not all the first OCIs are that critical, it's really just the first. And less than the oil you use and the interval it sees is how the engine is loaded and operated to achieve the last bit of break in.

For the most part, though, there's very little run-in in a newer engine because the surface finishes and geometry are so much more tightly controlled than in the past. This is especially true of engines where lighter oils are specified, and fine surface finish is a big part of allowing the engines to function well on thinner oil films.

For example, many parts how might have a DLC coating on them-- cam roller follower pins, etc. There is absolutely zero break-in on a surface like that because it's mirror smooth and harder than glass.

My local store has Schaeffer barrels in the back...

Bulk is common. Why not ask management. I have one GM on dealer PM - have been assured it’s AC Delco full synthetic - their website advertises this - Foxtrot said it’s common for them to do this - and he’s a big P66 dealer. (makes ACD).
They should be able to say what it is.

I am a 1-2k max OCI on the factory fill. My peace of mind. I get wanting to eek out the most value from the "free" OCI's at the dealer. Not so sure I'd want to deal with the dealer and the likely way over-tightened filter and oil pan drain plug. But I see the why and if I were going that route, I would use the same TGMO oil the dealer is using until I've had enough and then I'd switch to the Amsoil or HP or Mibil 1 5-30 and likely run 7500k OCI's depending upon your driving style.

It’s not part of the recall but some are failing. If there is a failure it will get a short block not a full engine replacement.

Not affected by the recall, but they're still blowing up. There's no formula and is just so random. This is definitely a poor design on Toyota's part.

 

[ARB1977]

Thanks for the replies. The reason for 5K this gives me the opportunity to cut open the filter when I do it at home. So far with 20K no metal is present.

This is not the case with my Pilot with the J35Y8 engine. First OCI was just under 500 miles, and second was about 4k OCI. Tons of contaminants in the first OCI, but still elevated on the next 4k. Admittedly, the wear/1000 miles is but a fraction of the first OCI.

God willing and the creeks don't rise, I'll be changing the oil this weekend at close to 6k OCI on the latest run (most on a long trip my wife took. OLM at 50%), 10k total engine miles, and will be sending in a sample for UOA.
