I have used Castrol 20/50 on mine since purchase. I have used both the FL1HP and the K&N oil filters and see no major difference between them in the oil pressure. I have also always added a can of STP at each oil change. I would not use a FRAM filter on my lawnmower yet alone my car. Somewhere I read about adding a 2-cycle oil additive to boost the zinc levels in the oil, but I never have researched it any further. I think it was an STP 2 cycle oil additive for the zinc, but I’m not absolutely sure about that...I believe the secret is to change you oil and filter with frequency. I never go beyond 2000 miles between changes. I always change it before winter storage. I try to never start the car and not get it hot before parking it again because the fuel vapors and moisture will not have a chance to vaporize out of the oil if it is parked so quickly. One thing, oil, additive and filter selection topics are like political and religion discussions.....what ever works for you...
