Here's some general information from http://www.underhoodservice.com/ac-oil- ... r-failure/

If simply replacing an A/C component, use this as a guideline for oil replacement:
Component Amount Of Lubricant To Add
Accumulator 2 oz.
Condenser 1 oz.
Evaporator 2 oz.
Filter Drier 1 oz.

In general, when replacing a compressor, the additional oil is added to that, and then the compressor (center part) spun by hand at least 10 times. But since you're replacing the accumulator and evaporator, I'd add about half the amount to each before bolting on. So from above information, at least 4 fluid oz. oil for you. The refrigerant will distribute the oil throughout the system, the oil does not settle in one place.

No special tools needed.
