10W-30 HYD replacement or substitute

XSKIER · May 5, 2019

An exhaustive Google search did not turn up much, so I thought I'd pose this question to y'all. Can I use AW68 in this application 50F-90F?

You mean a replacement oil for a Hydraulic system hat was spec’d to take 10-30 engine oil?
Jd Hydrau or Hydrau XR is designed to be such a replacement. I use it in my skid loader.

Because 10w30 is so hard to find?

Yes, wacker does specify 10W-30 in the hydraulic system. The term "engine-oil" is not in the spec, so there is where my confusion is. Do I use "oil" or "fluid"?

There is no industry standard separating the terms. If Wacker specifies 10w-30 oil that means engine oil. This is a fairly common recommendation for hydraulic and hydrostatic systems NOT containing clutch packs or wet brakes.

No. The issue according to JD is that engine oil specs are constantly changing ( CI, CJ, CK, etc). Also, zinc and other anti wear additives are being reduced because of potential harm to emission systems. JD said that they had to test and re certify every time a new motor oil spec would come out.
So they came out with “Hydrau” . JD owns the spec so it won’t change, and they are able to put the amount of zinc in that they want.

What does Deere have to do with a machine built by Wacker?

They have an oil that is designed to be a replacement hydraulic oil for equipment that specifies 10w30 motor oil.

I read the WACKER spec again yesterday. Anti-Wear Hydraulic Fluid 10W-30 in the hydraulic system. API rated SAE 10W-30 in the Briggs 16hp, and SAE 10W-30 in the exciter box.
