2 Quart -50° Snow PLOW Hydraulic Oil Compatible with Meyer 15134 Fisher 28531 Western 49311

Bought oil for spare , Incase ! Didn't have much chance to use , but with winters seem to be getting colder , I'm going to do a hydraulic flush and replace with this oil along with my knew tank heater. I replace oil in tank regular , but had first time it was cold enough , had to put a little heat towards tank to get going. Only 4star because I haven't had a chance to use .
