Valvoline makes a great product, back in my "dino" days it was my oil of choice. That said, ever notice that everybody compares their synthetic to Mobil 1? Everyone says their synthetic is better at this or that versus Mobil 1. These companies all take shots at Mobil 1 because it is the established standard. Valvoline, Pennzoil, Royal Purple, Castrol, Amsoil...all great products but I don't buy they hype that they are all better than Mobil 1.
