[DeTomaso] Steering rack adventures/ oil specs

[adin at frontier.net]

What do we think of the new trend (ok, not so new) of specifying water  
thin oil in transmissions?

Do we know more than the engineers?  If one were to use "better" (my  
term) lubricant, will it void the warranty?

Thoughts/opinions ok.

Verifiable scientific data more that welcome.
