Any way to compare anything or all anicdotal other than UOA's. Have sent the synpower in for a UOA.
Like the moly & boron add in Ultra that synpower does not have.
3.5L Gm engine approx 9k miles (5k on synpower).
Know Ultra has longer tbn but anything else to look for? Synpower still looked great on the stick as it should for 5k, know could have went longer but not concerned with long OCI's as I save enough doing my own changes.
Regards,
