I was looking at my wife's MacBook which is the same model as yours. I think if you have a high quality refined clear lubricant such as 3in1 electric motor lubricant, or a tapping fluid, you can put a drop or two down the hinge. Do one hinge at a time with the computer open and resting on it's side. After the drops of oil, work the screen hinge, the more you use it the more the lube will work in.

Alternatively, if you think light petroleum products are not the answer, perhaps try graphite. I thought about soap, which make a good lubricant, but I would avoid it because it may gum up in the future.
