seems they export castrol oil to north america from their german branch only.
check www.castrol.at = www.castrol.com
the filling station is in the south of vienna/austria.thats where all 0W30 is produced.

On a cold start you have a light weight, thin oil that is easier for the oil pump to push it to all the critical parts of the engine and prevent damage ot all of the rotating components as well as making it easier on the starter.
As it gets hotter it starts to increase in viscosity to provide added protection for high loaded components.
Have you ever poured say straight 40 or 50 weight oil? It's not as bad as 90wt gear oil but it sure doesn't pour like 10-30 does.
Just my $.02

This is done by adding stuff to oil that is not oil and does not lubricate. So, the wider the range of viscosities advertised on the bottle the less oil you are buying.
So, there is a limit to how far you can go with multi-viscosity oil before the disadvantages outweight the advantages.
