At FJ i was talkin to Jim Weigel (hope i spelt it right) who is the owner of AMT USA and during the conversation we brought up byproducts from the combustion of turbine oil. It can accumulate on combustion chamber/turbine wheel and cause hot/out of balance situation. I remember him saying you could run the turbine at low power and mix a solution of some type of grease cutting agent (dawn or joy dishwashing detergent) and water to keep the turbine internals clean. Other coments are very welcome.....just a kid shooting off his mouth here. Happy landings.

P.S. Jim's Super Hornet was absolutely amazing at FJ. The run-up was aww inspiring, can't wait untill it flies. What a craftsman.
