Keep in mind that the reason for the developement of the synthetics is the
need to provide a lubricant that does not break down under high heat
conditions. The newer engines are designed to run hotter for better fuel
burn, and an appropriate lubricant for such heat is necessary. The
synthetics came from the racing world in the beginning and have worked
their way into the conventional market.

I wonder what oils will be like when the ceramic engines that can burn
nearly anything for fuel reach the market? Temps that would melt engine
metals can be achieved with ceramics. Ceramics are reaching into other
areas as well. The window tint industry is just now releasing some new
ceramic coated tint films to the market. Where is it all going?
