    Anytime a compressor is replaced, the oil for each compressor within the manifold must be replaced. The scroll compressor uses Trane OIL00079 (one quart container) or OIL00080 (one gallon container) without substitution. Discoloration of the oil indicates that an abnormal condition has occurred.
