Hello,
I did interesting test with ACdelco supercharger oil and Mobil jet oil.
I know ACdelco supercharger oil is same with Benz OEM oil.
Anyway I will not use jet oil to supercharger.


ACdelco supercharger oil VS Mobil jet oil







After 5-days later...
The cup filled with jet oil was melted.
I think it can break oil sealing mechanism of supercharger.




Below is my personal opinion.
"The amount of Jet oil of airplane is checked before and after flight by mechanic. Supercharger is not jet engine.
Jet oil can be used at supercharger, but after long time use with heat, it may break oil sealing system of IHI supercharger as it melted plastic on my test.
So the amount of oil should be checked as mechanics of airplane do."


I have used jet oil for 7-years and 40,000 miles(Total 120,000 miles) and found oil leak in this year.
I changed all bearings and seals, but still leaks.
If I can buy supercharger which has no leak, will not use jet oil.
