Is the napa high mileage 5w30 a syn blend like their regular/conventional oil is? I don’t see any indication of a syn blend on their site. I’m guessing it it if it’s made by valvoline but would like to make sure.
Id go with the full syn high mileage but they do not carry it at my neighborhood Napa.
