Super S SuperTrac 303 Tractor Hydraulic Fluid, 5 gal. is rated 2.6667 out of 5 by 9.
Rated 5 out of 5 by from I have been using it in my compact tractor to put out round bales in the winter and move snow. I have never had an issue with it. I have about 800 hours on the tractor using this fluid. The loader is a little sluggish for the first couple minutes at -10 F but so is everything else.

Rated 4 out of 5 by from Great lubricant for lapidary saws My boss uses this product in his lapidary saws, cutting rocks with diamond blade saws. It keeps all the equipment and the rocks lubricated, cool-so it does not ruin the diamond edge saw blades; prevents rust, and it settles out pretty fast when placed in paper sack on top of a wire basket turned upside down inside a 5 gallon bucket. Strains out in a few days and is ready for more work!

Rated 5 out of 5 by from Use the correct product and your equipment work Xtreme Pure-Flo is a good economy product. It is just that. It meets very old specifications. If you have something newer than 1965, you should be using products that meet J20C like Xtreme Universal THF (white pail). Your cold weather performance will be fine with the J20C formula. This product is not a cold weather formula but will work better than most due to the base stock the manufacturer uses (lower point point base oil).

Rated 2 out of 5 by from Not for Cold Weather Changed fluid when I split the tractor last year on a Clutch replacement. I refilled with this fluid and installed a new filter. Have had poor hydraulics ever since. Cold weather operation is almost not existent. Must let system warm up for extended time to run lift or loader. Never had this problem with New Holland or Wallyworld universal oil. Changing out as soon as weather warms up if I can make it that long. I wouldn't recommend this for use in a tractor.
