Actually there are lots of them, even some monograde 40s in API SP per the API EOLCS. Amalie makes it.I don't even think there any any API certified monogrades anymore anyway.

No, but you just said API certified monogrades. Sorry I didn't see that you were referring to a 20-grade.20 grade?

Film strength? Where are you pulling that up?Pull up the film strength of a sae20 vs a 0w16 at say 250F, what do you get?
Mercedes-Benz is doing just that in some owner's manuals, specifying an approval with no grade recommendation although the approval allows for more than one grade.This is why I think the OEM's should not spec out a visc grade for use, but should rather just spec out a oil lube rating(s) as acceptable, and then perhaps highlight a oil grade that provides best fuel economy.
Pretty much. It says Arizona.
?? oil specs , that's where.Film strength? Where are you pulling that up?
I did specifically write "summer", and also "Phoenix". just sayin.I went through AIT in AZ during autumn and it was often below freezing in the morning, then 70F in the afternoon. Deserts get cold too...

A 0w16 running in a small hot engine when it's ~107-110F outside, looks like pee water.

How is this measured for motor oils??? oil specs , that's where.
Oils have film strength, some in psi, some in other SI units, etc. This # varies depending on oil makeup.
Viscosity does tell anything about how well the oil can protect from parts rubbing.
Smaller carbon footprint across the millions of vehicles using the 0w16. I get it, but that was not the context of my Q's.Your concerns about wear and durability are trumped by Toyota's requirement to meet CAFE standards in the US.
It's a very old subject here on BITOG. Check it out. To much words to quickly summarize here.How is this measured for motor oils?
Yeah, I know. But after doing oil for the last ~38yrs I kinda have an idea of my visual against what film strengths are.After changing oil in the hot summers of an oil change place way back when I can confidently say it all looks like pee water and spatters and burns. But looks might be deceptive as W16 and W20 oils rely less on VII polymers...
Lol now I know you don't know what you're talking about in regards to motor oils. You should stick to nuclear engineering I think.It's a very old subject here on BITOG. Check it out. To much words to quickly summarize here.
Oil Film Strength - Is higher better?
This was a film strength test run by 540 RAT over at Speedtalk.com. He used an oil load carrying capacity/film strength” tester to test 44 motor oils. The psi each oil supported was calculated, yielding the value of its load carrying capacity/film strength. All oils were tested at 230 degrees...www.bobistheoilguy.com
