I have used that sinopec cheap walmart oil, i used it for a about a month in a highly watet logged hyd system with no wet clutches/brakes. It sucks for normal hyd oil. My 3pt and loader was very weak with this sinopec oil. It got dumped and i put TSC premium universal in. Better 3pt lift capacity and loader wil actualy move at idle. The sinopec oil was very light viscosity compaired to the TSC house brand stuff. I wont use it again unless i have a water logged system.
