Castro GTX 20/50wt extra Viscosity

[sagaboy]

I just got some Castro GTX 20/50wt dino oil and the packing said: Extra Viscosity - I am a bit confused, can they claim something like that?

That's funny. Castrol has got to be the undisputed champion of marketing BS. I mean no one else is even close...

I believe that their dino and blend oils do start off at a slightly higher viscosity than most other major brands, per their PDF files.

Sure its Extra VIS. if you compare it to 5w30, i agree with DAN more BS from Castrol , the biggest deciver in engine lubricants.
