I'd deffinatley be inclined to believe that. I've seen vauge references in ford literature about using straight 50w motor oil instead of 90w gear oil in steering boxes... etc.. that tends to back up your info as well.
Like you say though.. kinda hard to compair a gear oil to a sae oil.. or a hyd fluid.. etc.
