I was reviewing the motor oils that meet the BMW Longlife 01 spec. I found Valvoline Synpower 5W-30 on a BMW website list, but going to Valvoline website, it's only the Synpower MST 5W-30 that meets the spec. I searched this forum for Synpower MST and didn't come up with anything. I apologize if this has been discussed previously. Is the MST product only available outside the U.S.? Thank you.
