Hi all, I'm trying to find an over sized filter for my GM 3800 v6. Basically, I'm looking for more oil capacity/more filter media since I tend to do extended drains. The problem is that I have no idea how to cross reference filter specs to look for compatible filters. I don't know if there is a resource, or if could somebody educate me on how to do this myself? Or if someone already knows the compatibility for S3387A (most brands) or M-101 (mobil one) or whatever the Amsoil filter is they could just tell me :P. Long term, I would hope to get a bypass setup before the year is out, but I drive roughly 1000 miles a week and would like the benefits of more oil until I pony up for the bypass kit. Any help would be greatly appreciated!
