Synthetic steering fluid for better FE?

I am wondering if it would be worth the expense to change the standard power steering fluid with synthetic to improve FE.

The only place that I can see that it should help is in reducing friction in the vane type steering pump. Pressures would still be the same of course so energy would not be saved there.
