X235 Dear Sirs, We wish to recommend one of your oils for filling a hydraulic damper but are not certain whether any of your standard products are likely to have the correct viscosity. Will you please let us know which of the three oils - Gargoyle Mobiloil 'E' " " 'Arctic' " " 'A' has a viscosity curve which corresponds most closely to that which we enclose. Alternatively, willyou please let us know what oil you supply that can be obtained generally which has a viscosity curve of this nature. Yours faithfully, | ||
