I know this horse has been beat to death, but I got a flyer in the mail today from Advance Auto Parts advertizing Quaker State Defy high mileage motor oil. it says "Boosted zinc for extra protection onhigh-wear surfaces"
I was not happy with Valvoline Racing oil with zddp,so I think I'll try the QS. $3.00 per qt.
