What does your manual recommend, or what does the Dealer recommend? If you don't have a manual you need to buy one. That's where you need to start! There are Hydraulic fluids and there are Transmission/Hydraulic fluids. They are not the same. Determine which is required and go from there... Once you know what type of fluid then you can do some research yourself on the different brands that would meet the requirements. I have my favourite brands and others will have there's.
