New Toro HYPR-OIL 500 high-performance hydro oil is specially formulated for use in all Toro landscape contractor equipment, including Toro Z Master commercial mowers, mid-size mowers, and new Toro Grand Stand stand-on mowers. When compared to other hydraulic oils, it reportedly offers greater thermal stability, higher shear resistance, and excellent wear protection for Toro's mowers. Unique formulation allows customers to double the service interval to 500 hours on 2009 model-year equipment, including the new Z Master G3 and Grand Stand mowers. When Toro hydro oil is used in prior-year Toro mower models, or is mixed with competitive hydraulic oils, customers should maintain the 250-hour, or annual, oil-change interval as recommended by the owner's manual.
