Depends what you mean by fine. It's a Resource Conserving oil designed for fuel economy. The good Castrol 30 weight is Edge SPT 0W-30 (aka German Castrol/GC) which meets Euro ACEA A3 specs for shear stability, it has the old API SL additive pack, and meets a whole slew of German manufacturer specs.
If you drive like an old lady then Castrol Edge 5W-30 is fine. Want an oil that meets Porsche, VW, Mercedes, and BMW specs, then go for German Castrol 0W-30.
