I know this has probably been posted to some degree, but I'm curious what the consensus is on what oil is comparable to others, that one can typically find at WalMart?
i.e.
1) top - Castrol Edge gold = Mobil1 EP = Pennzoil Plat ULTRA
2) high-mid - Castrol Edge Black = Mobil 1 = Pennzoil Plat = Valvoline Full Syn
etc. etc.
I like what I'm reading about Pennzoil Platinum ULTRA, but seeing as I haven't seen that stocked very often, I wonder if Castrol Edge Gold would be equal.
