i have been usiing moose filters with no-toil oil, my stock filter has been used a half dozen times and now it is splitting at the gasket surface &%$#@!? shouldn't it last more than that? my moose filters have been used about the same, i see one of them is starting to split at the filter basket post, it will hit the dumpster pretty quick, what seems to be the best filter out there? am i wrong in wanting more life from a filter? maybe i'm too harsh when cleaning them?
