Speakking of Steering Boxes . . .

[freewill2008]

For the Ross box in our FC, the book shows a list of approved oils
including one type of 'power steering fluid', a couple of ATF types,
and 2 or 3 motor oils.

While researching available synthetic oils, I found that hydraulic
oil parameters include base viscosity (like 30W), multi-viscosity
additives, and detergent additives (or not).

Because several types of oil are listed for the Ross, my conclusion
is that the recommended oils all have similar specifications for
viscosity and additives.
