I ran my 1st one with Injex, and after 10k miles it looked kinda bad, I ran my SKS with Amsoil Interceptor, and looks brand new still! I will only run Amsoil unless I am in the boonies and no one has it. That plaque means it was snow-checked, Polaris use to give incentives, like specialized plaque for the buyer installed, and a jacket, L.E. Club for Liquid snowcheckers, Fan Club for Fanners along with free gear and stuff.
