I know that some of Ford and Lincoln-Mercury dealers are being approached by Valvoline to sell that product rather than Motorcraft....My opinion, stay with Motorcraft products..please.
If your dealer does not put Motorcraft oil/filters, either buy the product at your local Walmart,then tell them to install it, or tell them that you want Motorcraft only or you will take your business elsewhere.
That is what I said to my selling dealer, when the dealer put Valvoline Premium Conventional Oil, and a Motorcraft Filter on my Mustang. The invoice said that the dealer put Valvoline Durablend, but the number on the invoice indicated that it was from a 55 gallon barrel, and was Premium Conventional Oil.
I, will go to a Lincoln-Mercury dealer, here in Austin to get the Synthetic Blend Motorcraft Oil, and Air/Oil Filters.
I know they use Motorcraft products as they put those products in my 1995 Mercury Cougar, and 1991 Ford F-150. I slipped into the garage to quietly watch the mechanic working on my car and truck, and he put all Motorcraft products in the vehicles.
My car gets better miles per gallon from Motorcraft Synthethic Blend than from Valvoline Premium Conventional Oil. I saw a 10% drop in mileage as a result of the change.
I have checked my mpg since I bought the car and used

I will not put Valvoline Premium Conventional again in my car....period....
