everyone has quirks i guess
Well in your case i would stick with oils that do still have the zinc still in em like brad penn which has owned the old kendall oil faucets for the last little while
I used to be a big kendall fan buts its no longer the same oil these days as they were bought out and are repackaging ConocoPhillips products
It is harder and harder to find quality oils that are safe for older style engines
