It's important to note that just checking ZDDP levels is not enough. Lake Speed Jr talks about this in one of his videos. As I mentioned previously diesel oils may have good levels of ZDDP, but newer formulations have higher levels of detergents and dispersants to control soot which negatively affect flat tappet engines.
