Oil filter Bosch or OEM BMW

That's the filter I've been using on my 2015 mazda 3, I've been getting them from Rock auto. So far no issues that I can see, took one filter apart after use and it seemed good.

Yes, absolutely can use Bosch and they were fantastic.

I pay 220 for M2 Comp. 7 quarts of oil and filter. Yeah it may be a high but I prefer peace of mind from a reputable Indy shop.

A good oil filter (I say BMW as I found they fit the tightest, best seal compared to even the MANN/MAHL filters specific to my N20)

Honestly I just use whatever BMW certified oil I can find at a good price. Used Motul this time, had Castrol before that. Bosch oil filter.

Castrol 5w-30-M with Bosch filter.

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

OEM Mahle/Mann are best. Next best is the higher end Bosch filters.

I'm perfect fine running this filter at my shop, Bosch can pay for the new engine and my time to put it in and my customer now has an engine with 300k less miles. Thanks bosh for your crappy quality control.

My mechanic said that a small amount of metal flakes in the engine oil filter is normal, but the amount here is significant and shows theres a something going wrong.
