Back when I lived there wagner and guard BF was perfectly ok to use. I used to buy them in bulk.
Sieken and nissin branded fluids were sometimes for sale? These were khaipyaa items and I didnt care much for them.
Caltex DOT4 was pretty decent too. And the best part was that in old times you could buy it in contianers of 155 ml, 333 ml, 1litre and 4 litres. Dont know if its sold now.
