Engine Oil!?

[tangmus05]

I just put this stuff in my mustang and it made the engine sound and run a lot smoother. You guys ever try it? If not, what do you guy use? My cousin told me to try it and I think I’m sold… Was a little more money but they sent it right to my house. This is the stuff I bought.

Please tell me you're new to the car seen if you never heard of AMSOIL?

Also, the OP linked to 10w30 oil. The recommended oil for a Mustang has typically been 5w20 as per the manuals (even though people will choose other based on environmental and usage conditions).
