who is using synth. oil in procharger?

I'm looking for those who are using any type of synthetic oil (5w20) in their prochargers instead of the ATI oil. I'm sick and tired of my oily intercooler piping and the crappy seals of the p1sc. I heard that others are running synthetic to help stop the leaks and was wondering how they were holding up. Any info would be great.

I heard pros and cons with this method, but since paxtons and vortechs use this type of oil, I'm not worried.
