So just use OEM fluid. No need for MT90 or RP.

If you're on a budget just call to the local auto parts store and ask for a standard GL4 manual trans oil and stop trying to throw money away on hyped up brand name oil

Out of curiosity. Do ford dealers generally keep this on hand or is it easier to order online?

MT90 is more for track cars and feels notchy when cold. Just use Motorcraft XT-M5-QS.
