But even if the car maintenance schedule calls for something less than 15K, you can use Mobil 1 Extended Performance for 15k. That's a pretty strong statement.
Way to throw M1 in there. He's asking about castrol edge. [/quote]
You do realize that I asked the original question? So if I brought XOM in on the OP, I brought it in on myself.
I brought XOM in because at the time Edge was introduced, my impression was that Edge and Mobil 1 Extended Performance were making the same 15K claim. Robenstein's post suggests that the 15K claims were different. You also might note my assertion in the op that the Edge claim was a competitive response to Mobil 1 Extended Performance. Whether they contiune to make a claim comparable to XOM was really sort of the point of the op.
