Oil filter LIQUI MOLY or Wix

Liqui moly ....run engine get hot pour in a can of ligui moly let run 10 mins drain oil replace filter and oil run vehicle 2500 miles repeat process

Wix or the Black Mazda filters.

I would highly recommend Rock auto, there website is simple old school but they are no bs auto parts store and will only show what does fit. They often show the real part your buying (say for tie rod), I've bought thousands of $ of brakes and suspension components over the last 20 yrs and always correct, they often sell OEM parts or the direct suppliers version of OEM which is unique. It will take some time for most of the aftermarket parts for the CX50 but at this point WIX or OEM Mazda are going to be your best bet for oil filters

If you're going to go aftermarket, the Wix/Napa Gold filter is also designed to meet Mazda's specs.

If you want to go aftetmarket I recommand using WIX filter they are good stuff

In my stable: The Nissans get OEM Nissan oil filters. The VWs get Mann The Mazda gets OEM Mazda filters The Mercury, Triumph, and the Toyotas get WIX.

I've used the Fram filter for the first oil change at 8K miles and the car sounded very rough for 10 minutes each time the car was started. Used WIX filter for 2nd oil change. No issues.

The OEM filter does a damn good job for what it is. If you're looking for an upgrade go with a wix or similar quality. Check the micron ratings when looking them up cuz brands like mobile 1 are not as good as they used to be.

Nice post, been using pennzoil platinum 5w30 for a while now and after seeing your results with valvoline I'm going to give that a try. Also gonna be switching to the wix filter instead of the usual subaru black filter to see how it goes.

Valvoline all round pretty much with the wix filter, i never plan ahead enough to order the oe filter
