any quality synthetic oil of the right weight will be enough as long as you keep a good OCI for turbo cars. T6 is good cause its cheap, heat resistant, and 5w-40 instead of 5w-30. the 40 weight is good for cars that are higher mileage and have increase clearances from wear, which is now most if not all turbo EJ motors. I put it in my EZ36 too. thats all the magic juice you will ever need.
