But if you really believe that Polaris has their own factory somewhere to manufacture this 'proprietary fluid', then give us a call because we've got some cheap ocean-front property in Wyoming for sale. A company called Lube Tech is the lube supplier to many Powersports OEMs. They are a private label for any OEM that wants lubes to sell with their one name and brand on the bottle. In the case of Polaris, a firm called Hilliard is the manufacture of the front diff fluid for almost all Polaris machines, straight from a tech at Hilliard. That demand drive fluid is nothing more than fancy hydraulic fluid. Cub Cadet also uses Hilliard as the supplier for their self-branded differential oil. Don't believe us? Juxtapose the specs and requirements of the differential fluid brands and give them a side-by-side look. You'll see that everything is exactly the same.
