Sorry but that's not an independent claim its a manufacturer claim which is basically useless.
sure CASTROL did the test at an independent lab, but the key her eis castrol did the test no one else.
Also did you have any issues with M1 why would you switch if you had no issues. Dont get me wrong if i had an issue i would switch but if i used something for years and it always worked i wouldnt even have a reason to look else wheres.
Just one last note that "test"
was done with 5w-30 a grade that should not be run in an S.
