i did that![]()
Well my gm supercharger oil has worked for 150,000 miles so I am going to stick with that.
GM S/C oil.
That's it.
Nothing else.
There are plenty of oils that may work, but GM SC oil has been engineered and proven to work. I doubt any of the people running other oils have done any significant testing (measuring temperature, bearing wear, etc). If other oils don't work as well, they won't know it until their SC fails. IMHO, I'd pay a little extra to know it'll work instead of hope it'll work.
