OE/HDO10 Civilian Version

[DarylB]

What's the civilian version of the OE/HDO10 for the power steering in a M923A2 and the best place to buy it? I understand it's hydraulic oil 10 weight, but whenever I see a thread about this, it goes into a discussion about changing to ATF or another rabbit hole . Thanks

So, for the next guy who needs this info...Hydraulic oils are rated on the ISO system and oils in the US are rated on the SAE system. So if you are looking for 10W hydraulic oil, you will need to look for ISO 32 hydraulic oil which is basically the same as 10W. Now that you know how it works, its a quick google search to cross reference and find what you need.

I flushed my PS system several years ago & have used standard power steering fluid from NAPA in it with what seems to be good results….no issues so far. (M931A2)
