What's the difference?

Does anybody know the difference between the Valvoline Roush oil and regular Valvoline Synpower other than price? Is the Roush oil worth it? I have a 05 Mustang GT. Thanks

Stock engine? if so Motorcraft oil will allow your engine to outlast your ownership of the car.

Yeah..stock internals. I just have a tune, intake and exhaust. I heard M/C is a great oil. Right now I'm using PP.
