Ok, here's my deal. I'm getting tired of trying to figure out which blend is best, and I don't want to pay synthetic oil prices. I don't want to rely on a sale because I want to stick with one brand. Basically, I want to use a conventional, one brand, and stick with it and change on a 3-4k OCI.
Of these (Valvoline, QS, Pennz, Havoline, Mobil Clean, Castrol GTX,) which one would you think is fine for 3-4k. I've always like Vavloline, but some have told me that Valvoline doesn’t seem to hold up as well in this mileage.
