Advice on first oil change and beyond - Mazda CX-5 2.5 N/A

Stick with Kirkland excellent value oil. There are many things better for cheaper in the world, some of them are Costco engine oil, hotdog, and rotisserie chicken.
Don't waste your money on marketing cost of premium oil that cost 2x, but perform 0.9- 1.0009 better in most cases. Unlike you do racing or crazy stuff, PAO base oil may benefit you. Just do 5-10k miles interval and have 1 million miles good run.

There are various 508/509 oil that mainlyb group 3 these days like Ravenol VSH, 90% HC, but also PAO Ravenol VSE. Both are rated 20k miles, but PAO VSE was born first. Group 3 oil can be as good as PAO for certain application, including VW demands.

I had a 2016 CX-5 with the 2.5L SkyActive engine. Car got totaled at 155k but the engine was spotless and ran great. Used 0W-20 most of its life but switched to 5w30 at around 110k.

This engine is GDI and is a bit prone to fuel dilution, especially if you do short trips. My wife did and UOA's showed fuel dilution. If you tend to do short trips keep the OCI's short-ish. No more than 5k miles.

If I recall the owners manual stated 0W-20 for North America for fuel economy purposes only. For the rest of the world it recommended 5w30.

Any quality synthetic will be just fine for this motor. They aren't prone to deposits unless abused and neglected.

Start here: https://www.amsoil.com/p/amsoil-oe-0w-20-100-synthetic-motor-oil-oez/?zo=515729

Then after a couple OCI's, change to this: https://www.amsoil.com/p/amsoil-signature-series-0w-20-100-synthetic-motor-oil-asm/?zo=515729

Thanks!

Why start with OE and then transition to SS?

Short OCI, less cost, API

Why does API matter early but not later?

Very very improbable possible Infant mortality hassles which are not reality just moral support for the owner.

Lol "infant mortality" = early engine death?

So make sure to do your first oil change at 500 to 1000 miles (KM's?). This helps get break in contaminates out like gasket sealer stuff and break in metals. The Motor Oil Geek on YouTube goes over this on his daughters car. His oil analysis shows the first change contaminants. Just a good practice on a new car. I saw you posted your question about a month ago so now is probably your time! Then run maybe a 3k change. Then goto 5k changes if you want. Any off the shelf synthetic will work. Clean oil is better than dirty oil.

I would look in the owners guide and see what exact spec oil your new Mazda calls to run and i'm talking full spec (s) not just oil weight.
When I owned a Japan car ( Subaru ) I liked the OEM Japan made filters but shortly after buying my 2014 WRX Subaru changed the OEM filter supplier just in the USA market to Fram. I then changed to WIX but I made sure the bypass valve spec (PSI ) in the Wix filter was the exact same as the OEM but for the most part choosing a OEM filter is safe but I like to research and know who is making that OEM filter and I don't trust the parts store guy and his computer to get the right...

I research who makes the OEM filter and oil. When I owned my WRX the Subaru oil was not crazy expensive so I did buy my oil at Subaru but the filter was WIX so go figure? IMO as long as the oil and filter is the exact same spec as the book ( I search the net for any new book updates after it was printed )

As long as kirkland oil has the same exact spec as whats in the user guide I would use it or even Walmart Supertech as long as the #'s on the bottle and in the book match...

The only thing in the book is API certified oil. That's it. Since 2023 anyway. Earlier versions showed API SM.

Basically, Mazda says you can pretty much use any oil you want, as long as it has the API donut on it, which Kirkland and Supertech has (same oil, just a different bottle.)
