08 250 6speed question.

Hello every one, I have been trying to find what kind of fluid to run in my 6 speed manny, I've head every thing from 90wt gear oil to 10w 40. no one can seem to answer my question. What does Ford say to use in the trans?
Can I run RP Synchromax? Mercon 5? what is safe for me to use in it? Ford makes a Manual trans fluid at 20+ bucks a qt. I don't know about that.
Thanks guys.

What does your owners manual call for?
