would you guys say Motorcraft is the best oil for a Mustang? Like over Havoline... Mobil 1.... all the others? I'm using synthetic, and right now it's Havoline, but a good friend of mine, who's in the Auto industry says ''motorcraft is made by Ford, for Ford, and it's the only thing that goes in my Ford''... But I don't know. Does Motorcraft make the best motor oil for a Mustang? It is a racing car. Mobil 1 is a racing oil.... NASCAR shouldn't be all that wrong.
