Oil filter Bosch or AMSOIL

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 have experience with the long drain intervals from Amsoil. I have 2 dodge vehicles with 3.6L engines both at around 130,000 km and I use the signature series 5w20 with Amsoil filter and I go about 18,000 km before I change the oil.

I do this every time. I buy my amsoil and filter and the dealer only charges me labor

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.

I'm running the amsoil remote filter, it will help with your oil quality.

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.

Happened to me last winter with a Bosch oil filter -- not even an el cheapo aftermarket filter, either. It looked someone had wrung it out like a dishrag.
