thanks, I found all the information in my shop manual after re-reading it again. My manual states when changing the evaporator to add 1.7 oz, condenser-1.7 oz and receiver 0.7 oz for a total of 4.1 oz. Denso stated the compressor is pre-charged with 2 oz of oil giving my system a total of 6.1 oz. At this point I plan to add the additional oil into the evaporator. The oil can then flow back to the compressor and be recirculated thru the system. I wanted to avoid adding to receiver as it may be absorbed by the desiccant and not allow a good evacuation.
thanks
