Mobil Gargoyle Arctic C Heavy and 300 products are high performance naphthenic mineral oils primarily intended for use in refrigeration compressors. They have low pour points and excellent fluidity at very low temperatures by virtue of being almost wax-free. Consequently, use of these Gargoyle Arctic oils ensures that evaporator tubes are kept clean to improve heat transfer and to reduce downtime for maintenance. They have good chemical stability and are suitable both for cylinder and bearing lubrication.

Gargoyle Arctic C Heavy and 300 are compatible with all refrigerants except sulphur dioxide. They are not recommended for use with HFC refrigerants. The moisture content of Gargoyle Arctic C Heavy and 300 oils is very low when the oils are packaged.
