Oil filter Castrol or STP

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 am running an STP filter on it.

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.

My filter looks just as I put it in after 5,000 miles, just dirty.

I have been using these since I bought the car (4 years ago) and they have filtered the oil fine, and also look just as the OEM ones did when it was time for an oil change.
