People used to rave about how good German Castrol 5W30 was - is it still available in the USA - or did Castrol stop shipping or change the formulation ?
I ask because while Castrol has USA fans of Magnatec or EDGE , spec for spec the oils that Castrol ships over to the USA are really nothing special (especially base oils , percentage of VII's contained a other specs. one might wish to compare against SOPUS , Valvoline or even against some M1 synthetic products ... I'll stop there and say if you are a fan of Castrol - then by all means continue using - but there is little doubt that German Castrol 5W30 was a different , better oil than what Castrol ships to the USA today .
