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.

It does give the weight and certifications. Nowhere does it say conventional, blend, or synthetic.

I have the turbo, 24 is coming in Monday.

They told me the original oil is a blend. It came out of a Mazda branded bottle. I don’t know who makes the oil for them. Synthetic oil changes are $20 more and they were adamant I should use the lower priced Mazda blend, since that is what it came from the factory with.
