Oil filter Bosch or STP

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 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.

Yes, the Bosch 3300 is correct for your car. I just used exactly that one for my oil change a few weeks ago.

I've been using Castrol high mileage 5w-30 lately with Bosch oil filters. I suspect I don't actually have the one I wanted, just the Bosch model fits my V. I think their premium line is supposed to be similar to the Filtech design. I added the appropriate amount of Marvel Mystery Oil to the pan about 100 miles ago. I haven't been calculating mpg, but notice the b20 engine runs smoother.

I use Mobil one and a Bosch filter on my 18 turbo. It's the same thing I use on every car I've ever owned.

Put some normal oil and an STP filter in it. Got it all back together, runs great. Ran around the block, noticed the oil light flashed when over 2500 RPM . Back in the drive way, let it cool down. This morning, put motor flush in, idle it for 5 minutes per instructions, and drained the oil and changed the filter. Looking at the filter, it seems collapsed. It doesn't seem horribly clogged - there is a bit of silt in the crevices, but that was expected. Is it just because of the cheap filter?

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.
