Oil filter OEM Subaru or Castrol

I use the black OEM filter and Pennzoil Ultra Platinum. The platinum and the Ultra Plat is the same formula now I’m pretty sure. I’d stick to the OEM filter too. It’s what my tuner recommends and I wouldn’t go against what he says unless it’s literally written in the stars

a 5qt Castrol edge 0w-20 container is $19. + $8 for a filter .. $30 every 5K miles is cheap imo..

I use factory filters and 0w40 Castrol (German one) when it’s on sale for $4.99 a qt. I too have 100k on my 2015 gsw 5MT and runs great I been using that oil since new.

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.

Buy a 1.8t Make sure to do a T-belt waterpump service. Then use oem oil filters and castrol syn. 5w40(syn. is optional for VW 1.8ts but I would personally only run syn in a turbo car). Also flush the coolant system. If you do that you will have a 1.8t that will a very nice running car and will not do you wrong.
