Hydrostatic Transmission Fluid Synthetic Blend SAE 20W-50

Especcially formulated to withstand the unique demands of hydrostatic transmissions in zero-turn, stand-on or ride-on mowers.

Hydrostatic drive is what makes this possible; the ability to apply variable torque to the left or right wheel. These systems require a versatile and robust hydraulic system and thus, an equally robust hydrostatic drive fluid. Lucas Oil has just the product for these mowers. This SAE 20W-50 multi-grade viscosity oil provides excellent protection against all lubricated parts, has added detergency, dispersancy and rust protection over motor oils, that are sometimes used in this application, and will not shear thin over time.

Additionally, Lucas Synthetic Blend Hydrostatic Drive Fluid contains a seal conditioner to discourage leaks, so the fluid stays in the mower, not on the grass. Together, these attributes result in a long-life fluid that truly holds up over time and extends equipment life. Recommended for all hydrostatic drive systems where the manufacturer recommends SAE 20W-50 fluid. Not recommended for engine crankcase.
