I happened to be on the Valvoline web site the other day, and noticed something that my interest those complaining about the changing oil formulations. Their 20-50 Racing oil specifically states: "Contains increased amounts of zinc for extra engine protection". Back in the day, I used this oil all the time in my AMX, and liked it a lot. Since then it seems to have picked up a "Not Street Legal" sticker, but I won't tell on anyone!
