Another one of the 4 year old threads you brought back to life. Only problem with reviving these old threads is in some cases the oils being discussed are no longer made and - not to mention as of Oct. 2010 the new API SN standards were introduced.
I'm using MC in my 04 150 3V with a MC or P1 filter. Excellent results. I'm sticking w MC blend but if I couldn't get it I would readily grab PYB and feel just as protected.
