I doubt the oil from a leaking oil-sender unit is affecting your clutch.
Your description sounds like the beginnings of a clutch-system failure.
There are two hydraulic sections to your clutch system, the master cylinder located right above your left/clutch foot when seated in the car and the slave cylinder which is down in front in the engine bay, behind the radiator and beneath the plastic clover that obscures your clutch/flywheel and slave cylinder. There's a hose connecting the two.
Either cylinder can be failing or they can both be failing at the same time. A failure often starts manifesting via a soft pedal; sometimes the pedal action firms up after a few pumps but at some point, all the pumping in the world won't solve the problem of worn seals in either of the cylinders.
The hose can also start decaying to the point that it's seeping fluid but that's easier to spot, especially with a friend pumping the clutch while you gaze down upon the hose.
Do you see brake fluid anywhere along this circuit between the master and the slave? Or inside the car where fluid could be leaking out of the master cylinder?
Do you have any idea (maintenance records?) when the car last went through a clutch job? You could try bleeding the clutch system (lotsa information in the archives here) to see if you get better action back. And then see how long before the problem arises again.
Clutch jobs on these cars are pretty straight-forward and I prefer to just replace everything in there at the same time (transmission seal, new clutch disc, maybe new pressure plate, new seals in the slave cylinder and a new master cylinder and a new flywheel bearing) and then forget about it for five or eight years.
The oil-sender unit is pretty simple to replace (a 5-minute job) and is a universal part you can get from most auto supply retailers.
