I know there's always a debate about changing the oil filter every OCI vs every other OCI,but what about doing the oil and filter on their own specific change interval? I do 10k OCI's and so my 15k filters (FU and the like) don't coincide with OCI's. So it occurred to me doesn't it makes sense to just change the filter on it's own 15k schedule regardless of when the oil gets changed. Anyone do this? That seems to get the most out of everything and I won't be throwing away a FU with 1/3 of its life left. I expect a lot of folks might say they won't remember 2 different intervals, or that if they're under the car anyway they want to do both and get it out of the way, but aside from the doest it makes more sense mechanically speaking? FYI me the filters in my RAV4, Prius, and Soul easy to get to and take just a minute to replace so it's not a big deal to do it whenever.
I have to admit it feels weird to not use a new filter every OCI mainly because I think of that extra old oil I'm leaving in, but that's probably more my OCD than any engineering reality.
