So I’m fairly new around here, and need to do a rear tranny fuild change, so I searched a few threads that mention "chain case" lube as being a great choice instead of the Polaris stuff……plus I can probably find it a lot closer to home. But the folks at multiple auto-parts stores don’t know what it is.

So where can I find it, and what are the options? Are there different viscosity options, different brands, etc?? Thanks for whatever advice folks can provide. BTW, I have a 2012 Sportsman HO with EBS.
