All hydrostatic oil is not the same. That’s why Wright engineers recommend that owners of Wright mowers use the same durable hydrostatic oil at changes that’s in the mower when it leaves the factory. Wright dealers make that easy by stocking genuine Wright hydro oil by the quart or case.
Wright has specified and is offering this synthetic 15W-50 hydro oil because it withstands higher temperatures and has better shear resistance properties than other off the shelf oils. And it protects the system for longer intervals between changes. Wright engineers recommend that the oil and filter be changed annually, or every 500 hours if the mower is used in cold or harsh weather conditions. They also recommend checking the owners manual for any oil change recommendations that may be specific to your model.
Wright dealers also sell hydro oil filters, which should be changed each time the hydro oil is changed.
