Oil filter OEM Toyota or OEM Mazda

I prefer to buy Pennzoil Platinum (high mileage or ultra) 5w30 and use a WIX or Toyota filter, whichever is cheaper.

A change with that oil and an OEM toyota filter costs me a bit more than $23.

Oil and filter every 5k miles give or take a couple hundred. Air filter... when it gets dirty or once a year. Which ever is first. Most of the time it is the year.

every 5k miles for me to stave off the inevitable HG issue. 160k miles on a 3rd gen which is notorius for HG problems if you don't change your oil.

I’ve always used the OEM filter and Kirkland 0W-20 oil on my 2013 Skyactiv because I remember reading on the forums that due to the high compression of the engine the Mazda filter is specialized to handle that. Not sure if it’s true but no problems yet on 7.5k OCI.

This is normal. Funnily enough, a Toyota dealer is probably the cheapest place to get a 0w20 oil change (TGMO from Exxon-Mobil) and OE filter for your vehicle.

When I worked at Scarb.Lexus Toyota I remember the oil filters were definitely a different world of change from the filters you pick up in stores, everything from the seals to the inside filter paper were superior so I always get my filter from the dealer.

OEM for the engine oil filter.

Costco brand full synthetic w Toyota filter. Change every 5k or 6 months

The Miata is pretty easy to work on. But ironically, one of the simplest jobs is a major PITA, changing the oil filter The thing is buried underneath the intake manifold.
