I would wonder if even though its a FORD dealer they use Motorcraft oil. I dont know anyone that works for a Ford garage. But my one friend works for a GM garage and he told me they use Bulk Pennzoil 10w30. Simply because there is a Pennzoil terminal nearby that sells them the oil, not GM goodwrench oil. I know another friend that works a Dodge garage and he told me they use Bulk 10w30 Carquest oil by the drums, which he says is Valvoline. Which we know is Valvoline with a weaker ad pack. Dealers I am sure are trying to make money too and as long as the specs of the oil meet the manufactures specs, I cant see why they would not use a oil locally at a better price. Since I have seen no big Motorcraft oil tanker trucks. The best way to find out is "wonder" back into the garage area and see what the drums say. I think most will pleasantly surprised to see 10w30 is going into about everything, regardless of the manufactures specs. I have seen this at a couple of dealerships and about every quick lube. If you price the oil by the drum at a supplier, the 10w30 is "alot" cheaper, which is probably why alot of them go this route, its not a considerable savings for us, but on a 100+ cars it would be.
