of oil usually found in that component using one of the oils shown above. Here is a guide:<br />

● Compressor (same as amount removed from old compressor OR 75cc/2.4 oz. minimum)<br />

● Condensor 22cc/0.7 oz.<br />

● Evaporator 53cc/1.7 oz.<br />

● Accumulator/Dryer 95cc/3.0 oz.<br />

● Lines 22cc/ 0.7 oz
