Everything I learned over the years about rebiulding turbos.. Is they prefer zink. And dont like detergants. I run any oil in my truck cause its just a NA gas motor. I run synthetic in the stock 1g find turbos like synthetic. But I run the sh!t out of my 2g with a diesel turbo so give it what I believe will take the most abuse and offer the best protection. And try to keep it conveniant and affordable since I change my 2g oil way more then I change my other vehicles oils.


But thats just me. And yes Royal purple is just an expansive name. Some would say the same for Amsoil.
