A little searching around the "net will bright up all sorts of posts/arguments about lifter noise in those engines and what oil is best to use. Of course, Kohler says to use theirs. Linked below is ONE discussion on the subject. (I have NO connection to "Bob the oil guy.) Tick, tick, tick...   [Reply]  [No Email]

I have had more than one customer bring a mower in with that complaint, using automotive, water cooled engine oil. We changed oil, put command oil in, and lifter noise was no longer an issue.   [Reply]  [No Email]
