Toyota Crown takes 0w8 oil

[mva]

Consumer reports still ranks Toyota reliability excellent based on 2022, 2023 and 2024 models. This is after recently substantially refreshing almost every model.

I’m going to trust that Toyota engineering is still solid and I’m currently running the recommended 0W16 in my 2024 Prius with confidence.

They only got beat out by Subaru which has much simpler power-trains, no hybrids and no EV.

For the life of me I've never understood people's faith in CR. They are all paid off it sure seems.

And unless Subaru has finally figured out CVTs, oil leaks, and rattling exhaust heat shields I call BS.

Why don’t they just make a straight 0w and be done with it. Ridiculous

Because they like screwing us one little step at a time.

It would have to be either an "SAE 0" grade, or a "0W-0" multi-grade. No such thing as an "SAE xW" straight grade. I've never seen a straight SAE grade oil with any "W" rating indication anywhere on the bottle.

I've seen some very old Winter-only oils, like SAE 20W, but that was from long before API performance standards existed or were relevant. I think I posted a screenshot of one years back on here.

Probably before SAE J300 existed, as J300 wouldn't allow an oil to be marked as "SAE 20W" ... it would have to be marked either "SAE 20" or "xW-20" if it was sold as a multi-grade.

J300 has gone through a lot of revisions over the years (see: MRV update) so it's quite possible it was compliant with J300 at the time. The table does still show them as SAE viscosity grades (the Winter grades), they just lack any data for KV100 Max and HTHS. I haven't read the actual standard lately, so I assume what you state is now explicitly called out there? If that's the case, then I assume it wasn't back when these grades were relevant.

Edit, found it, and it was API SE!

^^^ I searched all over for any oil labeled as just "SAE 20W" or "SAE 30W" these days and found none, so probably not allowed. Wonder what that old SAE 20W can of oil you found would pan out to be if labeled as a milult-grade?

Yeah, would be really neat to see an analysis of it eh?

If it's not specifically prohibited under J300, it's probably allowed, but I don't see any reason to produce one with modern base oils, which is likely why we don't see them.

Looks like you can still buy a 20W-20. Can't find any modern oil sold as a "SAE 20W" single grade however. If someone did sell oil labeled "SAE 20W" it would probably confuse people, or they would think the "W" mean weight.

Found an OE reference to it (1955):

Here's another vintage can of it:

^^^

Below 32F, and used in something like that guess it wouldn't really matter what the KV100 grade was since it probably wouldn't get that hot and stay pretty good if KV100 was measured. No disputing that SAE 20W existed back in the day ... but doesn't seem to be around today. 20W-20 is as I linked earlier. Guess it could be labeled SAE 20W instead of simply SAE 20 if someone thought it was going to suitable for winter use.

Looks like you can get hydraulic oils in the straight Winter grades:

Check out this gem of a table from Indonesia:

^^^ Must get pretty cold in Indonesia. But does anyone actually make a straight grade SAE 20W these days for use in ICE? I can't find any, except for the hydraulic oil example not for ICE use.

I doubt it? But it's possible I guess

I'm not a thickie or a thiney . Anything below 0w20 is witchcraft.

I’m just waiting for some of that sweet, sweet 0W-0 to come out. It’s gonna be awesome!

What's next, straight 0w?

It already exists, it’s called Water.

Can you get it from your sink faucet???? LOL
