Letter from Lloyd's Register

Type Approval by Class for Hydraulic Oil Filtration System is not required. However, the surveyor may witness the installation and testing if it is part of the class item.

Letter from Land Transport Authority (Singapore)

As the FS Series bypass oil purifiner system is an add-on unit to remove contaminants from the oil (i.e. engine oil) through its filtration system in which improves the fuel consumption and engine efficiency, we are pleased to inform that we have no objection to its installation onto motor vehicles.
