They are good quality oils. Very good for cleaning due to the inherent nature of the type of lube it is. OCI depends on too many factors so I can't answer that one for you. It should serve you well through 7.5k+ based on UOA's.
Thanks, just not familiar with their oils. The Chrysler dealer sells it in the parts department and was curious about it. On the OCIs I was wondering if it was capable of longer I intervals like PU, Amsoil, and M1 EP if conditions were right.
