I just put royal purple in mine ... simply cause its the only synthetic that I can easily obtain (NAPA or Orielly's).
I've read good things about Redline and Amsoil too. Basically, most people like the synthetics. However, I think adding a cooler is probably the best way to extend the life of the fluid, pump, and hydroboost.
