Until all the fuss here about ZDDP, I was using any oil in all my old vehicles. Nothing has happened to them, they continue to run normally. I think I will carry on doing the same.
I believe you need ZDDP on rebuilt engines for the break-in period.

From what I've been able to tell, the ZDDP issue was one of camshaft break-in on new or rebuilt engines with flat tappets. I have never found any evidence to the contrary and have never paid any attention to it. I have used all types of oil in my engine under the harshest conditions. But that's my preference and I certainly don't criticize others who feel more strongly about the ZDDP issue since it is easily addressed in various manners.
