I need to change the hydro oil in my Super Z. The manual states only 20w50 SL/SM rated motor oil. I don't remember it specifying synthetic, but I know other manufacturers that use the same pumps and wheel motors do. Do I go with conventional or synthetic? Is there anything special about hydro pumps and motors that require or can be adversly affected by certain additivies? This model does have a hydro oil cooler and electric fan.
Also, would anyone have a hydro filter recommendation. I can pick one up at the dealer, just didn't know if anyone has an idea for an improvement, if there is one, to the one Hustler sells.It's most likely from Stens or Rotary anyhow, not Hustler. I came up with a Wix 51551, Fleetguard HF6056/HF7608, Purolator H32010,and Donaldson P551551
Any insight would be appreciated.
