Hey guys, Since I've been reading different results on oil filters and the great info on this site, I have come up with a question. In non-extended drain intervals, what filter is the best option? For example, I have been running Amsoil Marine 10w30 oil and an Eao15 filter on my EFI Ford 302 Boat engine. I have changed the oil and drive fluid at the end of each season before I store it for the winter. I plan on continuing using the Amsoil Oil in it, but after seeing that the Mobil 1 filter may actually be better than the Amsoil filter, I am thinking about changing. I don't know what the mileage equivalent of a summer of boating is. Also, my "summer car" is a 06 Mitsu Eclipse 3.8l v6 that I have run Amsoil 0w30 and an Eao13 filter since it was new. I have about 23k on the car right now, and it would be LUCKY to ever see 10k on the oil. Again, same thing, I change the oil and filter before I store the car for the summer. Would I be better off using the PureONE filter (which I have read on this site that it seems to be an excellent filter) or even a Mobil 1 filter, or should I just stick with the Amsoil filter?
