Also also, I recently discovered an oil company based in Monteno, IL called High Performance Lubricants, and after studying a few things and talking with the guys there, this is the oil I'll be running from here on out. It uses a base oil of PAO, mPAO, Esters and Alkylated Naphthalene. This means really high quality base stocks and a killer additive package. I honestly think it's the best engine oil on the market right now.
