Changing Oil Every 2 Years?

The Car Care Nut suggests this same interval even for the new models.
Yes, he also suggests using only Toyota motor oil, as if its not made by Exxon Mobil...

Also your vehicle that specifies for 5k or 6 month, is most likely spec'd for 5w30, and using his Toyota motor oil only train of thought, it would make sense since Toyota 5w30 oil is conventional...and I wouldn't even run 5k OCI on conventional motor oil in Toyota engines, I have seen what that can do first hand, many many times.

running a good full synthetic oil (obviously depending on driving habits and engine application) should be able to do longer time intervals if the engine gets up to temperature often.

I like TCCN's DIY and diagnostic videos but his engine lubrication advice is lacking.

So what? It's manufactured / formulated to Toyota's specifications.

He also suggests using only Toyota Genuine Parts and these are made by all sorts of OE suppliers: Denso Aisin T.Rad etc etc.
 
Toyota calls for 12month or 10k mile oil changes. Only for "Special Operating Conditions" do they call for 6 month of 5k miles. And even if you do hit these conditions, they only apply if the majority of your driving falls under them.

most people fall into this category...especially during the colder months.

California is generally hot and a lot of people drive long distances there, not the rest of the US is that way.

exactly which specifications? Toyota literally requires the current year's API spec when printing the owner's manual, there is absolutely nothing special about Toyota motor oil.

Using genuine Toyota parts is totally different, Toyota and it's parts are known for reliability, Toyota owns Denso and Aisin. Also fitment is a big issue when using non-OEM parts.

Aftermarket parts and engine oil manufacturers do not have the same R & D budgets either, you can't compare apples to oranges, this is a bad comparison on your part.
 
Similar situation with a motorcycle that has been well under 1k miles / yr. since the mid 2010's. I WAS doing O&F (@ ~$120) spring and fall, then ~2018 just went to every spring. Now it been 2.5 years but only ~1,200 miles.

Maybe crazy; my biggest fear was actually the oil filter media (Being soaked in petroleum for >24 months) breaking down > spewing stuff downstream > blown engine.

Today, I am actually changing the filter, this will also require a top-off of 1 Qt.

FWIW: I only use OEM (Yamaha) filters and have been using Amsoil 20w-50 "V-twin" (Really, just because it was convenient)

I assume the exact formulation Toyota has specified is proprietary information. Sorry, you'll never know.

The fact that Toyota oil is made by Exxon/Mobil and not Toyota themselves (as if Toyota operates oil rigs) is meaningless - that was the point.

Toyota does not outright own Denso nor Aisin. Toyota is a shareholder in both Denso and Aisin (and mazda, and subaru, and ... and ...). They are a giant corporation.

again your comparing aftermarket parts, which can clearly have a quality and fitment difference to motor oils, that is an awful comparison, the fact that you are here on BITOG and haven't understood by now that using OEM labeled motor oils will NOT give you any sort of benefit is mind blowing to me.

Toyota is a majority shareholder...

I'm not sure what I said that leads you to believe that. I think you are trying to make an argument / debate where there isn't one.
 
If you are checking the oil level before use, I think 2 year OCIs are OK. I try to stick to the 1 year changes on my less driven vehicles and equipment, but schedules sometimes compete, so going over is not a source of anxiety.

Hate to break it to ya, but it's whatever oil company can give them the best contract and meets API spec. I seriously doubt there is any secret sauce in their motor oil. They slap the Toyota badge on it and charge a premium.. Apparently the marketing works.

Who said there was a secret sauce?

And they don't charge a premium at all. Have you ever purchased it? I've bought it multiple times per year, for barely over $3 per quart.
 
I cant say what you *should* do but what I can share is I have (5) crown vics in exellent shape. Being so many I cannot accumulate miles on all of them. I find that even when the oil is 3-4 years old, it still passes the UOA sent to blackstone. Becuase the engines are stable with regard to shedding metals, I am not concerned. What is important is to do that 2 hour road trip to get the oil up to temp and boil off any water / gas accumulation. If you cannot do this, then yes annually makes more sense.
 
I may be wrong, but I think, ( my 80's fried brain fog again, sorry ), I read somewhere that oil gets acidic laying around inside an engine from combustion ????? I don't think that would be too good for rings and seals. I would do an OCI 1X a year and a filter. Get it good and hot ( fans going off/on to get the moisture out), and dump it while it's still hot ( well, not that hot. You don't want to scald yourself ) You know what I mean :)
