Amsoil seems to be great oil and doesnt sheer at high temp. I ran ss 5w30 in my 5.0 for 8k with over 30 passes at the track. Sent a sample off to blackstone and they said it was perfect, could have even put another 4k on it.
Anyway i couldnt wait... About to put my car on a lift and see if my 12 has the cooler on it
