315 Simplex Supreme

Simplex Supreme is engineered to meet the widest possible range of equipment manufacturers’ performance requirements. Simplex Supreme 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. 

Simplex Supreme offers stable, balanced friction performance, which provides smoother, quieter and more efficient operation. Simplex Supreme is compatible with other fluids on the market, which eliminates the need to drain the system before using Simplex Supreme.

Simplex Supreme meets and exceeds the service make-up and refill requirements of transmissions, differentials, final drives, hydraulic, power steering and wet brake systems of this type of equipment, especially those that employ a common reservoir or sump.
