I would advise that you buy the OEM fluid , Other ones can damage the seals and the pumps ,I dont know how it damages it but some of them do , You wont see the damage now , but eventually it does . I had to replace my pumps for that exact reason , the pumps wont break they will leak , after I switched back to the OEM fluid , Iv never had a problem .
Its not so expensive , About R50 i think or more a bottle .
