'morning,

Some years ago I read about modern oils lacking Zinc (ZDDP) due to modern cars catalytic converters. I bought some break-in additive with the intention of adding some at every oil change promptly forgetting about this after the first one.

I just saw something online about synthetic oils being even worse for old engines purely because of the lack of ZDDP, so synthetic oils are still better than mineral but only provided you add the break-in additive yourself.

So, does anyone here do that?
