Walker Hydro Oil !

[Mowman]

How do you drain the oil out of the reservoir? Then what type of 20w do you put back in ? Can Mobil 1 be used in the reservoir ? Thanks for your input. Mowman

Mowman,

If you are talking about the resevoir on the hydro unit, there is a plug on the bottom of the unit. Take that off to drain. Most of the oil in the resevoir should drain, but the rest can be sopped up with a clean rag. Yes you can use Mobil 1. Walker recommends 5w-30w.
