quote:Do you want to run synthetic or mineral/conventional oil? What oil are you running now? How is consumption with this oil? Where are our Australia boys at? I don't know quite all what's available to you down there, but if this was my ride. Conventional - HDEO 15w-40, period! Synthetic - 5w-40 HDEO, or 15w-50 and 20w-50 PCEO's.
