AND if you look further down the rabbit hole you will see all these cars aren't loaded up with tons of miles either. I could buy JDM spec DOHC vtec engines with low miles for cheap. They dont allow all that high mileage stuff over there so they sell it over here. At a certain mileage/age parameter set by the "man" they have a inspection that is so rigerous that its not worth keeping it. I'd like to see some of these 16 and 12w's survive a 18 year old in Japan where the best aftermarket parts are made. Especially with boost! I dont think or know of any 0w20 that is HTO-6 spec'd but if there is which there could be...I dont see a 0w16 surviving 10k oci with DI and Forced Induction going 200k or more. I dont see it going even 100k after people add bigger exhausts and various HP/TQ increase parts. To even make a 16 remotely feasible it would need a 5 qt capacity and a oil cooler to get high mileage on one. Someone on this forum has stated they use oil wt recommended overseas for same car. Unless I live in Hinton,Alberta or Yellowknife I would do the same thing he is.
I hope I am wrong and 16W makes it but I doubt in my lifetime it will be as mainstream as 5w30.
I think that I both agree and disagree with the various points you are making. Keeping it simple, I think that something as sedate as a Toyota Camry will probably do just fine using 0w-16 on American roads for 200k miles. Boosted vehicles, turbos, direct injection or turbocharged direct injection? 5w-30 sounds better to me under those circumstances. Presently I am off the reservation, testing 5w-30 M1 EP in my son's 2016 Accord with the 2.4 liter Earth Dreams DI engine that is spec'd for 0w-20. We should have 10k on that oil by mid November.
OTOH - there is this 2017 Prius V, not in my signature for lack of personal work on it, that I am tempted to try a 0w-16 in...
