Damn! We've all been here. Is it synthetic? Look, this is rocket science to us Opti owners. The point is that Opti's do work different from most other 2 strokes and therefore it is wise to use their oil. Regular synthetic Quicksilver oil is OK to use in emergencies, and it's interesting to note that it's no longer called Quicksilver Optimax Oil, just generic Quicksilver 2 stroke. The answer, I guess is that for a once off, it would be OK, but I'm not the owner. To be honest, I would probably go for any other make except the Shell if you can get it, (remember what their petrol did when it was first released?) but at a push, any high quality 2 stroke oil is probably the same. Is it designed for injection or mixing? This is important I would guess. There must be some wise engineers out there who know - it is a huge problem even on the Solent. You try and buy Optimax (Quicksilver Synthetic) oil in Cowes for example.
