My advice: either use high zinc and phosphate concentration oil like the ones in the following list – or – if you buy oil randomly, add some zinc & phosphorus additives.
So if you’re buying oil from the shelf, which is still better in terms of the quality than 30yrs ago, but please make sure you add some ZDDP, a 4-ounce bottle to a five-quart oil change.
