Oil filter Bosch or Castrol

I did Castrol Edge Euro Car 5W-40 with a Hengst oil filter, but if you want to spend a little extra most people recommend LiquidMoly

I used the Castrol once, and have been buying the assembled kit from ECS ever since. At 73K miles, now, and change it every 7-8K.

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.

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 Edge 0w 20 with the Dexos1 and an STP gold filter done at 2k.

7500 miles religiously, including filter every time. Full synthetic 5-30 Castrol.

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

Bosch filters are almost as bad a FRAM now.
