Additive Corrosion

[Fast Eddie]

Finding that an oil adative is breaking down internal aluminum compressor parts creating a white material that is clogging the distributor tubes in the system. Any experience with this same issue.

How do you know that there is an additive in the oil that causes corrosion in aluminum?

What oil and refrigerant are you running? I seem to remember that R134a/polyolester oil can attack magnesium in compressor parts.
