We have to clean the oil of Hydraulic System for the submarine where special oil is used. it is refered as PIGCAL - ( OR PIGCOL - 89 )Probably it is manufactured by Chevron.
Has any one any idea about this oil and its specifications ? Will it be comatibal with standards seals used in the filtration trolley ? Of course if the specifications are available I can easily check with filter system manufacturer.
