Does anybody know how much pag oil to put into the ac compressor? or how much r-134 to put? This is going into a 93 es300.

take it to a shop. It might look more expensive at first, but if you put too much in of either, you can cause the compressor some serious damage.

besides, if you need to add refrigerant, there must be a leak somewhere in the system, best to get it professionally checked out.

The NAPA specs show that it came with R-12. Are you certain that it has been converted. If it has, are you certain that the problem that you are repairing might not have occured because of a less-than-thorough conversion job (that may still need to be fixed).
