Not sure what Valvoline patents for Restore and Protect are in play currently but with the significant popularity of Valvoline's Restore and Protect - you have to believe that Mobil and SOPUS would love to develop a similar oil with carbon cleaning abilities . I’m sure Mobil & SOPUS (and maybe Castrol) have already studied Valvoline Restore and Protect samples to study and reverse engineer . Again , not sure with what Valvoline parents may be in play for Valvoline Restore and Protect but safe to say Mobil & SOPUS will want to counter Valvoline with their own carbon cleaning new formulation oils and take some of that Valvoline Restore and Protect market share away . If or until that time comes , kudos to Valvoline for their success with the Valvoline Restore and Protect oil release .
