Toyota Crown takes 0w8 oil

What's next, straight 0w?
Maybe ... Recently, I was made aware of Diamond Like Coatings which allow gearboxes, and maybe other parts, to run without oil. While I recall hearing that they've been used in a racing situation, I don't recall if it was just testing or in actual competition.

These coatings have many applications (and come in a variety of designer colors) The "coatings are environmentally friendly and can be used to reduce friction, wear, fretting, galling and corrosion."

I suspect, but do not know, that they are being at least considered for use in an engine. In any case, there is technology out there that will allow us to go in that direction.

Able to run without oil is one thing. Does it run better?

Plus oil does more than just lubricate.

DLC is applied to the compression and oil rings in the A25A-FXS engine
 
Nah, it'll be just OIL, no numbers etc...

Speaking of, I saw oil jugs with oil brand 7I0 in some Russian YT videos, was always wondering if it was just OIL upside down 🤣

My Mazda has DLC on various components in the motor from what I’ve read. I think it’s fairly common

I also have a knife with a DLC blade.

Do you know if the DLC is the same or similar to that used in the firearm industry?
 
Toyota, doing everything but trying to actually make fuel efficient engines.

Maybe I'm off base here, but who else engineers IC engines with as much development and advancements for general purpose commuter cars(aka for efficiency) than Toyota? Their latest 4cyl generation is getting very close to the theoretical limit of thermal efficiency for ICE using fairly novel intake flow pattern, with head design and con rod stroke angle IIRC. Also, designing an engine to work with ultra low viscosity oil(oil passages, bearing surfaces, pumping system, multi-stage cooling) in itself doesn't indicate effort in engineering a fuel efficient engine?

Maybe I'm not looking at all the angles here, but from what I've seen, Toyota is one of the few makers out there that actually try to engineer and develop high efficiency ICE engines. Rather than just haphazardly cobbling together 20 year old peripheral technologies like GDI, low tension rings etc then throwing on a lean as possible ECU tune.
