I used Fram filters almost exclusively until I found the Castrol filter. I've never had difficulty with a Fram. I've had to return to Fram, since the only store that carried the Castrol, in my area, has been K-Mart. With their financial difficulty, they have sold out and will not re-stock. So, I'm back to Fram.
Just a note: I'm not familiar with the practice of filling the filter prior to installation. Interesting concept. What's the advantage, besides not starting the engine to get the oil flowing (which one usually does, to check for leaks, anyway) and then adding oil if necessary?
For a real "oil leak" experience, you should try leaving your drain plug a little loose. Sure makes for a helluva smoke screen on the Interstate.
