Are oils created equal?
Hello expert resource folks! I looked through several pages of past threads but couldn't quite find the answer to this. I found TriFlow aerosol at Mills Fleet Farm, (thank you MacyBaby) but not a TriFlow oil. I have 3-In-1 brand light machine oil and Singer sewing machine oil, both new (well probably from the 80's) and old that came with my 1947 Singer. Does machine oil go bad? Are all of these good for cleaning & de-gunking? I'm not up to refinishing with the naptha & linseed oil & all yet. I just want to not wreck my machines by cleaning. Dumb q's but ya gotta start somewhere. Thanks!
