ZTR Hydro Oil

[Riches139]

I purchesed a Cub Comm. ZTR for my lawnservice in 2004.
Hydro pumps and motors call for regular 20w50 motor oil.
The system runs very hot in the summer months.
My question is, would 15w50 Mobil 1 reduce the running temp significantly due to the reduced friction?

Thanks to all who reply!

Mobil 1 would be ideal for that application.

How about Mobil 1 V-Twin 20W-50? Although, I don't think you could go wrong with Mobil 1 15w50 in that application.

IIRC, Exmark requires the use of Mobil 1 15W-50 in their mowers' hydrostatic pump systems. So I'm sure it will work fine in your new Cub Cadet.
