Best Oil filter for Mazda 3

I'd go with the OEM Mazda Oil Filters but any high quality synthetic 0w20 will work fine.

[The filter was this](https://m.autodoc.co.uk/bosch/11156545)

You could do another oil and filter change to see if it was that or if the oil was just a coincidence.

0w20 Mobil one synthetic and Mobil one filter since 50,000 km to now 205,000km on my 2014 mazda3. Engine runs great.

I do use Mazda filter rather than aftermarket.

I use Mobil 1 synthetic 0w20 with Mobil1 M1-209 screw-on filter for the 2012. I've been doing this for these cars since they were new. We don't put too many miles/year on these cars and so I change the oil every fall and every spring. Never had a problem.
