A pretty simple and straightforward first step. I have a spin-on oil filter adapter and use a K&N HP-2009 Filter with a little under 7 quarts of Hick’s Oils Collector’s Choice 20W-50 motor oil. A fresh copper crush washer was used under the oil sump drain plug. The drain plug on my aluminum sump requires an 11/16″ wrench for removal.

I ordered the oil from Moss Motors and the filters directly from K&N. You don’t need a filter removal tool for the K&N filter as the canister comes complete with a 1″ wrench fitting!
