How could a 0W-8 have maximum engine protection. More like minimum engine longevity.
The oil is for Hybrid Electric Vehicles (H.E.V.) and Plug-in Hybrid Electric Vehicles (P.H.E.V.) fitted with newer gasoline engines. These engines don't run 100% of the time, and when they do run, they don't develop the heat typical of a regular ICE. Lower generated heat means that the oil runs cooler, and is, therefore, thicker, providing more protection. For that type of engine in an appropriate use cycle, the oil should do well. It's not designed for a small-block Chevy ...

This is BITOG, please don't use logic here. Only ill-conceived theories based on emotion are welcome.
 
It would be interesting to do a test, 0W-8 versus 5w30 on 2 identical cars, ran for 200,000 miles and then to do an engine teardown to examine engine wear (Perhaps 2 NY City taxi's would be ideal).
 
It would have to be in Europe as the Toyota Yaris actually specs grades from 0w-8 to 5w30 in the owners manual. Here's a thread about it https://bobistheoilguy.com/forums/threads/0w-8-in-the-new-non-us-yaris-hybrid.341590/
Interesting thread. Toyota is really going full speed ahead with specing nearly all their brand new cars for 0W-16, and the Yaris in Europe for 0W-8. I trust Toyota, as they are the most reliable car brand over the last 2 decades according to Consumer Reports.
But it will be interesting to see how many of these ultra low viscosity vehicles make it to 200,000 miles over the next decade.

True film thickness is a big contributor to wear protection and to pull it off you're going to have to create some very well formulated base stock and additive packages. So much so that I actually think it ends up being more expensive to formulate a 0w8 good enough to match a regular 0w-20 in wear that the fuel savings are probably not enough to justify it. There's a guy on here that bought 0w8 which was very expensive instead of just using the cheaper Mobil 1 Extended Performance 0w20 for 10-15k and most likely ended up spending more money on that thinner oil even with the miniscule fuel savings taken into account. At the end of the day it all trickles down to the cost effectiveness throughout the whole lifespan of ownership.

Even though I don’t trust 0w8 on its face, we have to realize no “performance” engine will likely spec this. Plus, remember Japanese domestic market has both displacement AND HP limits, meaning those engines are significantly different than what Americans are used to. When you consider that 600cc 3-cyls are the likely target market, and both bearing sizes and surfaces must be designed for 0w8, there is the possibility that this oil will provide a fine life of service, to its intended market.

It's a pretty specific application(s), no one is saying put it in your Shelby. These are cars that struggle to get anywhere near an operating temp...
