- All posted Blackstone oil reports have shown decrease in bearing wear (when switching from 10W60 to 0W40).
- If cars like a GT3 and GTR's can run it, I don't see a problem with running it on S65 if oil pressure doesn't drastically change
- Not really a factor, but a bonus. It's $55 for 10qts of M1 at Walmart. I change every 5000 miles.
At the end of the day, it's up to you to decide if you want to switch or not. I don't think there will ever be a definitive answer as to what you should run because there are so many opinions. It also depends how you use your car too. If it's mostly street driven, then absolutely I would switch to M1. I've also taken it on mountain runs during hot days and it performed very well (car has never seen track time though).

Thanks for the information
I may consider switching it later.
