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.
Exactly what I think. I already do oil changes every 5K.
Since Mazda USA on Twitter wouldn’t respond, I did send the question via their support website. It is so old that it doesn’t have CX30, 50, or 90 as a selectable vehicle. I picked CX5 and explained myself in the body of the email.
I’m going to do synthetic, but I do want to understand why they recommend this.
