First time I’ve seen a dealer turn down money.
Is it okay to switch my CX-50 to full synthetic 5w30?
5w30 is what’s in it now, it is just Mazda oil (whoever makes it). I think it may be a blend, but no one has comfirmed.
MazdaUSA on Twitter hasn’t replied to me in a year, so I will try here.
Due to the recent flakiness around that engine in the CX-5, I would do exactly what the book says.
