Actually, no, Edge is a distinct product with completely different ratings than Syntec; and is currently available only in a couple of weights that are not usable in a Porsche. Castrol also has a “Pro Edge” product line in more compatible weights, currently unavailable in North America, that is getting very favorable reviews overseas…………
