Simplex Supreme Tractor Hydraulic Fluid (THF) is blended with superior polyalphaolefin (PAO) synthetic oils, 100% paraffin base oils, a high viscosity index and a carefully balanced additive package. The unique formula allows Simplex Supreme to withstand higher temperatures (up to 250°F more) than conventional oils. Schaeffer's Simplex Supreme THF meets the performance requirements of a wide range of tractor and construction equipment manufacturer standards - including John Deere's J20C specification.
One measure of the protection given by the tractor hydraulic fluid is measured by an FZG wear test. Simplex Supreme surpasses this OEM requirement, providing higher levels of performance reserve.
Simplex Supreme exceeds the J20C requirement for pour point performance in lower temperatures. Formulated to maintain good viscosity, Simplex Supreme keeps equipment protected under a wide range of operating conditions.
