Oil filter Castrol or Mobil

Mobil 1 is the most consistently highest rated oil. Royal Purple's filters are probably the highest rated, but Mobil 1's filters are also highly rated and "Just use the OEM ones" comes in third.

I would go with 0w30 or 0w40. I changed my oil and filter at 1k with castrol 0w40 and it runs just fine. I did find a few metal flakes and slivers in my oil filter. Guess they were left overs from being built.

I'm not sure if the Mobil One Oil Filter is the best synthetic oil filter, but it is probably much better than the cheap Napa filter.

Mobil1 has been a 'gold standard' for a long time. I'd use it, along with a premium filter (Mobil1/etc.)

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.

5k Mobil 1 0W40 with Mobil 1 filter.

I have used the mobil one bigger passat filter for years, works great! more oil capacity.

I use the M1-301 as well, the added capacity from the oversized filter is just nice for peace of mind. It's a PITA to get in and out though.

i used mobil 1 301 filter in my passat for a year never has black oil oh ya my motor has over 200k on it with 15psi on it. mobil 1 is good stuff

My last car ran bosch filters and mobil 1 5w30. the guts were spotless. for my break in period on the new one i used mobil 1 filter. for probably longer than i should have. filtered very well. oil had very little specks in it.
