This is such a basic item that I can't believe I have gone this long not noticing that I have a fuel filter installed instead of an oil filter. The filter I have been using for an oil filter is the Baldwin BF940, which was on the boat when I got it and I have just blindly been replacing since then. I went to order a replacement and was surprised to see it listed as a fuel filter. It seems to be working, but I would guess that it's too fine compared to an actual oil filter. Or maybe not? What are others using for oil filters? Purolator PL14610 is one I have seen mentioned. This is for a Universal M18 engine (probably uses the same filter as the M25).
Thanks,
Doug
