Forgot to mention there’s also a small engine version for portable generators and the like… in Cold Climate edition, no less. I just got some 5w40 for my generator. Also got some of the SXS series for the diffs, trans, and engine in my Polaris 450HO Sportsman!I don't see The hydrostatic Transmission fluid on the website, and yes I can call but, wondering why the website seems to not list all the products?
