Default Odd recommended oil viscosity

Has anyone noticed the manual states you should use 0W-16 oil? I actually did not know this was an option to buy. i had to do some research on it. Although it has only been available in the US since late 2017, It has been a standard oil choice for small economy engines in Japan since before 2000. Here is a direct quote from JXTG Nippon Oil & Energy.
"0W-16 oil was introduced in Japan before 2000. 0W-16 showed higher fuel economy than 0W-20 engine oil. It will also give you remarkable quick engine starts at cold temperatures. There are several concerns [about 0W-16 oils] due to their lower viscosity, like increased wear, increased oil consumption, and lower oil pressure. But our long history [with 0W-16] has addressed these concerns. The 0W- 16 project is just the beginning of what JXTG Nippon Oil is striving to do to offset carbon footprints. Actually, we are currently working on a 0W-8 oil"

As well, a quote about the concern of increased engine wear from very low viscosity
"Those were concerns with having such a low viscosity oil, but with more than 15 years of background in 0W-16 oil, we are able to address those issues and create a benefit of increasing fuel efficiency, when compared to 0W-20 oil."

Being with Lexus, this was a new one for me so I wanted to pass on some info for new owners. The company making the oil states changing from 0W-20 to 0W-16 improved fuel efficiency by 2%. The manual states you can use 0W-20 but it should be replaced on the next oil change. I added the page from the manual. Hope you guys are enjoying your new cars.​​​​​​​

Seems like a good way to get folks to bring their cars back to the dealer vice other facility.

Nah. You can get 0w16 at any automotive stores or even walmart. The Prius and other hybrids have been using 0w16 for some time now.

I remember the cries of fire and brimstone when 0W rated oil came out..."it's sewing machine oil".
Time will prove or disprove this approach but it would seem that synthetic oil should survive this trend also.
If I lived in Southwest USA I believe I would substitute 0W-20 anyway!

I do not remember this, was probably too young. I am interested now though. You are right, when new things come out, people look for only the worst.
