I would switch to a high grade 10w30 synthetic which ever brand you want. I like Redline oil, Amsoil, castrol syntec, mobil 1. Detergent is in oil to hold dirt and carbon etc. Unless you have done a fresh clean motor build and only race the car with light street driving and plan on 300mile oil changes get some "normal" oil in that motor. Also glad to hear you have hooked up the factory turbo how they intended it to be hooked up, off the head.

I run my GT4202 off the head, 300 some miles and going strong.
