Hello, I have read the oil thread with great interest. I have a 2014 Mustang GT track Pack. I will never race it, I drive pretty short trips, roughly 10 miles at a time. I drive pretty easy with occasional spirited driving getting on the freeway. I live in Dallas, TX and will put maybe 20k miles per year on the car. From what I have gathered I should use AMSOIL 5w-30 or maybe 10w30? I am not too sure. Thanks!
Mike
