Why don't you just bleed it properly, drain the pipes into a temporary catch tank, and leave it on pre-mix for a 20 mile ride?
You'll soon see if it's working, as the (what shuld've been injected) oil will be in the catch tank.
As I've siad before, I've never personally seen one fail. Not to say they can't or haven't, but I've never seen it happen.
I'd personally do the same as Steve and Fontyyy, but it's up to you.
