I wish Amsoil would list the base stock in the > MSDS for their "100% synthetic" oils. I downloaded some information a year ago on Petro Canada Duron synthetic oils. The attached Safety Data Sheet says, Chemical name CAS-No. Concentration lubricating oils (petroleum) C20-50, hydrotreated 72623-87-1 70 - 90 % neutral oil-based lubricating oils (petroleum) C15-30, hydrotreated 72623-86-0 30 - 50 % neutral oil-based lubricating oils (petroleum) C20-50, hydrotreated 72623-85-9 30 - 50 % neutral oil-based, high viscosity Zinc alkyldithiophosphate 1 - 3 % What does that say about its performance? The SDS says, "It is suitable also for passenger car and light truck diesel engines, and spark ignition engines." Of course, where to get it is a problem ... Craig
