Thanks copperfieldkid.
The reason why I have enthusiasm with Jet oil is "Oil leak in my supercharger"
Not just scatter a little but sprayed a lot as below pic.
Also I found oil outside seal when I pulled out SC clutch.
Then I found it melts plastic cup so I suspected jet oil may melt rubber seal during long time use.
May the reason of leak is not caused by jet oil but in my experience and circumstances I have to doubt jet oil.
It's my personal opinion and I have no objection jet oil is good for turbine engine.
From now I will stop jet oil issue.^^ Thaks a lot.
