he also told me your car is shiny and lot of stuff done, lot of work.

Not sure if you experiencing it but I always see metal shave at my drain plug with valvoline and Castrol, Valvoline produced less. After switching to BP, I don't see it anymore. I do see wet at valve covers, but not sure if it's BP or the age of the gaskets. The good thing is the metal shave is gone, and also valve noice is much much less.
