No, you cannot.
On a 1993 Ford Explorer : None , unless it has been converted from R12
R12 ( unless it has already been retrofitted )
R12 unless it has been retrofitted for R134.

R12 was used up until 1992. R134 Is what is used now, and you can even check to see if yours was converted from R12 To R134A
r12 but get a 134 kit and change it over for about 35.00 (wallmart) you have to be a regesterd mecanic to get r12
