Power Steering Fluid Type
Hi all, I normally hang in the 7.3 SD section, but have a friend with a 1993 f250 with the 351 in it.
My question, is what fluid does the power steering unit take on that truck? I know my SD diesel takes ATF, but have no idea on that one.
Thanks for any help, Tom

I got a chuckle out of this. Owner's manuals don't update themselves? 
I've looked up a couple dozen threads on the topic and responses are split pretty much 50/50 between regular ATF and Ford's Type F spec.

I always use universal synthetic ATF that covers Mercon V. Synthetic seems to be a bit quieter, although that may just be me convincing myself of that.

I'm always a bit nervous going to synthetic well north of 100k, but at least that probably addresses the 'better viscosity' concerns of using the proper stuff.

Being a ford tech, I can tell you that Mercon V doesn't make it any louder than type f from my own experience

You would know better than me. Do you know if ford changed the power steering pump design at all after this era of trucks? I noticed that's when they stopped saying to use type F.

EDIT: I would also just like to add that Ford PS pumps are just loud in general.

I don't believe they did, but they don't even use type F in dealerships anymore because everything is replaced by Mercon V or Mercon LV. There isn't much to change on a power steering pump other than pressure or pulley size conidering it is just a simple belt driven pump for hydraulic fluid
