Clutch Fluid Cap

This may sound stupid but how do you remove the clutch fluid cap? I have a '94 SL and there's this metal bar "thing" that seems to be blocking my way and I can't get a good grip to turn it. Thanks guys.

you dont have to turn it, it pulls off but it is really tight

it has a strong grommet that holds it in from memory, they are always a bugger to get off

Is clutch fluid the same thing as gear oil or are they 2 different things?

Oh okay, I just got back from Kragen and they said clutch fluid is the same thing as brake fluid so I just added some of that. :)
