My machine shop recommended Brad Penn motor oil. Really?

The negative effects on the cat converters due to zinc and phosphorus in the engine oil only appear after high mileages of use with the oil. Unless you use some kind of "racing" oil with very high levels of those compounds, you should have no problem. Your engine was already using higher ZDDP oils from birth to 2010 when the API "SN" oils became the rule.

As John Sargent says, your main concern is the rod knock and how severe it may become.
