I don't agree with that at all. If you or I had access to the motor oil buying habits of all Ford owners, I would be surprised if Motorcraft oils would be over 25 - 30% of their shopping lists. Reasons are a) the Motorcraft oil brand is a small percent of all oils at major retailers such as WalMart, AutoZone and other retailers where oil is purchased. B) It is not widely advertised and C) It is not on the lips of the average motor oil buyer. Even though I asked the question at the Ford dealership, I would bet, the typical person has been using Pennzoil, a WalMart Super Tech brand, or whatever was easy to get their hands on. If my wife were the buyer, she would wouldn't give what brand 5W20 she used, a second thought. So, if someone with a very high odometer mileage was using Pennzoil, Valvoline, or even Mobil 1, I would think that fact would enter the conversation - even at a Ford dealership.
