Just curious as to what most TT members are using oil wise. I'm using Mobil 15-50 and have close to 24000 miles on my Z. I'm soon going to do a CMJ fuel system upgrade so didn't know if at that point it would be recommended to use another type.

 

mobil 1 15-50 is all i used on my stock engine. but everyone on here convinced me that i should run amsoil from now on.

 

Cool, hey phunk i sent you another pm in reply to your last one
