I switched from black *** old motor oil to straight synthetic motor oil and now my clutch feel maaaad soft, not loose, but a whole lot easier to push in, is this because i been unknowingly damaging my clutch, or does the switch in motor oil cause a difference? no tranny fluid, motor oil. I just bought the car 2 months ago so this is my first oil change and i notice a huge difference.

 

Changing your oil would not make your clutch peddle soft. I would recommend a bleed of your clutch lines (low point first, then high). Use good synthetic brake fluid, and get all the old fluid out, exmaine for leaks along your clutch line as well.
