Our preferred oil is CPIs CP-4628-68 as it is a PAO but it will also resist O ring shrinkage. Grasso have approved this oil for use with their screw compressors on CO 2. Use of CP-4628-68 also means that we can put the same oil in the CO 2 compressors and ammonia compressors on a cascade plant.It would obviously be an advantage to use a miscible oil with CO 2 and we have some experience with POE which satisfies this requirement, but our tests were not conclusive.t is very important to specify Esso Zerice S type oil for the specified applications listed because Esso sell their mineral oil called Zerice, which is similar to Shell Clavus mineral oil. Zerice S type oil can be recognised because it is a clear, colourless liquid and does not have an oily appearance.
