CAM2 PROMAX Premium Universal Tractor Hydraulic Fluid. Any Good??

[timebak]

In my RK37SC, I've always used the Rural King Providence store brand of "Premium Trans-Hydraulic Oil, Multi-Trac Formula for Use In Most Applications" which meets the John Deere J20C spec, and costs about $15 per gallon. But they also sell "CAM2 PROMAX Premium Universal Tractor Hydraulic Fluid", which also meets the John Deere J20C spec, but costs around $9 per gallon. Is this CAM2 Hydraulic Fluid as good as the RK Providence Hydraulic Oil?
