Sorry, but my research shows that there is only 130ml of oil in the S/c12. I could be wrong, but this is what I have read.
Also, I have read about using oil thats made for air conditioner pumps. And a guy from a performance shop stated he uses 2-stroke oil??? Holden informed me today that there super chargers are feed by the main engine oil whilst running ??? Again, this is only what I have read and been told.
I to am in the same position and am not sure which oil to use, before I put my GZE into my AE92 sedan. Here's hoping what ever oil I use, doesn't stuff it. Let me know if you find out for sure. Cheers, Kevin
