Can any of you tell me how long you're keeping your by-pass filters on without changing? I know that Amsoil says that I have to change it every other full flow change but since I'm only doing 8k OCI's at the most, I was thinking on keeping the filter on there for about 24k or so. I've read about some members here keeping them on this long without any problems and just touching it to make sure that oil was circulating completely.
