Im really not sure what to say about the latest Oasis ads.
Trying to position a fruit flavour drink which is pretty chocked full of sweetners and other stuff as a water substitute is a little strange.
Personally when I drink it the chemically taste makes me more thirsty...
Would you get away with positioning Pepsi Max as a substitute for water? I doubt it, yet thats what the new campaign seems to heading towards. The only possible difference I can see is that the acid in fizzy drinks hurts your teeth...but really, I find it quite close to Sunny Delight levels of dodgy positioning.
