Kenrico,

Mobile Jet II is an acceptable oil to use. From what I see when I service turbines running that oil is a very large amount of carbon build up and it takes a lot of work to clean them. The bearings are definitely coked up but not as bad as the Aeroshell 500. I'm sure you will see the performance drop off the closer you get to 25hrs. I would rate Mobil Jet II right above Aeroshell 500 but it does not do the damage like Aeroshell. If you have a way to get our oil to your country I would switch to the KingTech oil, you will have a much happier turbine that will continue to make the power you enjoy all the way to servicing.

Regards,
Dirk
