just use honda mtf. you will need 2 bottles, 1 litre each. From dealerships or honda pit stops it cost rs1330 per bottle. Independent shops outside around rs1000 (make sure genuine).
Also its good practice to replace the crush washers. The drain bolt will use the same washer which is used for the oil drain bolt, 14mm size.
The fill bolt uses a 20mm washer. Part number 94109-20000.
