For original vehicle owners who use a quality synthetic oil running conservative OCI’s - might Valvoline Restore and Protect be a solution looking for a problem ? I would fall into that category plus before Valvoline Restore and Protect came along I used Rislone R&P engine cleaner approx. every 3rd oil change . Still , I’d be willing to switch to Valvoline Restore and Protect - if I knew more about wear protection , ability to stay in grade , NOACK and other attributes of Valvoline Restore and Protect (outside of cleaning ability) .
