I'd like to have this confirmed also. I've been hearing for some time now that Rotella no longer contains ZDDP. Maybe it's versions other than "T Triple Protection.

As for Walmart oil being good because it's Quaker State keep in mind these box stores are famous for inspiring confidence with a name brand but the item is made for them and based on a set price point.
