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.

    100% this.

    I’v had my civic for 8 years and I’v done 2 oil changes every year for the whole ownership. About 90% of the oil changes were made at costco (always synthetic). Never had ANYTHING happen to my engine; never had to do any repairs. Hope this can reassure OP.
