I have a Margalla GLX Powerpack 1998 model. I want to know what brand and type/grade of oil should I use for its power steering functionality? I would prefer a product from Caltex, Shell or any other major company with local presence.
Please also let me know how frequently (10,000 KM / 20,000 KM / 50,000 KM / etc.) it needs to be changed.
Note (if it matters): The car is used exclusively in the city and I seldom speed it to more than 120 KM/H.
Any help in this regard will be highly appreciated. Thanks.
