What oil are you guys running in your /6?

Well I am just curious about what oil you guys are running in your /6's?


Brand: (Ex: Valvoline, Mobil 1, Amsoil, etc...)
Grade: (Ex: Conventional, Diesel, Synthetic, etc...)
Weight: (Ex: 10w30, 10w40, 20w50, etc...)

Here is what I recently used with my 66 Dart:

Brand: Castrol GTX
Grade: Conventional
Weight: 10w30

I would just like to see what everyone else is running. I just dont wanna be running the wrong kind/weight of oil in my /6.
