Toyota Crown takes 0w8 oil

[kschachn]

What exactly is the reason for such, to understate it, dumb solution? If this is the only way to squeeze out bit of mpg, then it will be interesting ride.

Dumb is an understatement. More like deliberate engineering malfeasance, a class-action lawyer's dream.

These arguments about how and why thinner oils are required get goofier and goofier. Now we have the oil pump having a design that can starve the engine.

I am having a feeling they will be back at Munich asking for more engines.

Not in the maintenance manual.

Unlike the maintenance manual, Toyota doesn't specify what it means. (HiHy shown).

If Toyota was worried about thicker oil causing issues (the operation of the oil pump, etc) or engine damage, they wouldn't put that statement about using a higher viscosiy oil being "better suited" for higher speeds and load conditions. It's their way of saying they understand that thicker oil protects the engine better under some situations.

Something tells me that they put that statement in all of their owners manuals, by default. I have not seen that statement in the service manual.

What does the service manual specifically say about oil viscosity?

Next time I do a TIS subscription, I'll put a screenshot in this thread. But IIRC, it only lists the specified grade and nothing else.

If it doesn't say anything about the grade being "required" or that the warranty is "void" if not used, then it's just another recommend viscosity specification.

So. Toyota decided to bring back the Crown.

Clever.

Not made in Indiana....

If it comes with 0W-8.. I guess 0W-16 is sooooooo like today's 20W-50.

I'm guessing wider bearings, like constantly referenced with newer engines designed to take the thinner oil.. not sure if this one is made in Japan still ? If Toyota says 0W-8 (for more than just break-in oil??!!) then one must assume they know that they are doing.

Fast forwarding to those that will be putting in 10W-30 after warranty.

Let's hope there is a large sump capacity[/i] and maybe a large cooling system as well.. I have always said, the cooling system plays a HUGE role in keeping the engine cool, some say a motor oil's primary directive is to transfer heat, some say it is to provide lubrication.. it heats up faster in the summer, as well.

Your thoughts on this 0W-8? (I'm thinking it must be pretty resilient stuff if they can spec it for the engine and actual, real use.)

0W-16 for Severe Service, anyone?

 

[PimTac]

0W-8 is not a problem except for availability which should get better as more automobiles use this grade.

Japan has been using it for a decade now. No news of engines blowing up.

Too many trips to Victoria Secrets perhaps, lol.

That would be Victoria's Secret ... sheerly you knew that.

"Secrets" is when you go to more than one.

But, where is there an unrestricted speed on a road of in the US highway system?

2) Do you expect Crown owners to be towing heavy loads? Probably not. They would have a real truck instead for towing duties.

Maybe Toyota thinks 80-85 MPH is high speeds ... plus, while doing that in hot Texas and Utah weather. Fact is, they made the statement in the OM. If it didn't matter to them, they wouldn't even put that statement in the OM.

What does the OM say about towing with it? And on top of that, what's the max allowed load with people and cargo?

Where does Toyota think 80-85 mph is high speed? Maybe that's what you think.

There can be typos in the manual. It is reviewed by humans after all.


It's more of a throwaway paragraph. Because if it did matter, Toyota would go into more detail on what constitutes high speed and extreme loads, like they how they defined "Special Operation Conditions" in the maintenance manual.

The GVWR is 5020 lbs (XLE & Limited) minus curb weight of 3980 lbs, which is only 1000 lbs of cargo and passengers. Toyota does not specify a tow capacity, but it won't stop people from installing a hitch if the aftermarket makes a hitch for it.

Lol nobody is going to tow with a Toyota Crown.

Not the owners manual but Car and Driver listed the specs and under towing they have NA.

I’m not sure anyone would want to tow anything with a Crown.

What makes you think Toyota doesn't think it is, just because you don't think it is, lol? Driving at a sustained 85-90 MPH in hot weather is going to get the oil hotter and thinner than driving at a sustained 55-60 MPH in cold weather.

The same statement "typo" in every Toyota OM? Doubt that.

In any case, Toyota knows that thicker oil can protect better under more extreme use conditions. They can't put other recommended viscosities in the OM in the USA like they can in other countries because of CAFE. So all they can do is make a general statement that higher viscosity is "better suited" for better engine protection under more exteme use conditions. They are correct, it does.

Death Valley is where automakers tend to do their extreme hot weather testing, and the speed limits around DV is not 85-90 mph, and you probably missed about how an ECU controlled variable discharge oil pump works.

If toyota really cared about that statement, then they would further define what it is to the same level of detail like "Special Operating Conditions".

Know what's funny? The Tundra with the i-Force MAX engine makes no mention of this. Guess Toyota doesn't expect extreme loading on their full-size truck like they would expect a senior citizen driving a Crown.

 

[0W-16]

A 4,000 pound car (Toyota Crown) speced for 0W-8. HTHS probably < 2.0.
I don't think I'll ever want to buy a new Toyota (as nearly all of their new model's are speced for 0W-16 or 0W-8).
And they use the variable electric oil pumps which makes sure engine oil pressure is always at low end of what's adequate
to save tiny fractions of gasoline. I doubt any of these new Toyota's will make it to 200k miles.

They do NOT use an electrically powered oil pump. These new Toyotas will outlast whatever POS your are currently driving.

It’s amusing how the discussion has moved from essentially “the engine is designed for the oil and might be damaged by a higher grade” to “the (electric) oil pump might starve the engine with a higher grade” to “the US doesn’t drive at high speed” as the moving target of silly justifications.

It helps when you understand that there is no technical reason. It gets you off this merry-go-round.
