RPM, Hi, I have no oil filter fitted to my 1935 Mk1 Ruby engine and I use reasonable quality (Known brands) of multi grade oil 10/40 or 20/50. I do however change the oil regularly and work on the assumption that new clean oil is better than filtered oil. Oil is relatively cheap compared to an engine rebuild and is a lot easier and quicker to do.
