Hi all, my husband was member of this forum. He enjoyed talking with you all. Unfortunately he passed away. Now I have 2 Roush mustangs. I have a 2008 P51A and a 2007 Stage 3 both with less than 3000 miles. I haven’t driven them much at all since his passing. He was the only one who maintained the cars. I really need to do an oil change and was wondering what is the best oil to use. He had purchased a couple of cases of Roush Valvoline 5w-50. Apparently they don’ make it anymore, What do you all suggest.
