it, happened while i was in neutral, light turned green and my clutch felt way light

i could not go in to gear, i started pumping to see if i could build enough pressure to get it to disengage so i can put it in gear and drive to a place to pull off the road but nothing improved,

i push my car in to the closest driveway so im not in traffic in a construction zone. i go get a master cylinder (fortunately the person whose drive way i used drove me there ( thanks random guy),

i put the master cylinder it in, pour Moter oil in (i forgot to the fluid at the store) i then was able to pump it up and get pressure to put it in gear,

but it would lose the pressure so i had to keep putting it in neutral to pump it to use the clutch, but i did make it home.

is it the slave cylinder or could it be the fact i used Moter oil, mabye its cause i didn't bleed the system, ill report back when i finddout. btw it was getting dark.
