Is it necessary or worth it to change the manual gearbox oil?

    If you ask Ford, they say no. I tend to disagree, but you'll have to make your own decision.

    My preference is to change every 100k or so, but older oil will tend to 'wear out' earlier than decent modern stuff.

    The other factor is that the oil you have will be fairly old, and will have met the specs of that time and things have moved on, so oil today will be of a better overall standard than what was fitted to your car at the beginning of its life. My suspicion is that you will have the (odd) old-style fitting of auto transmission fluid, plus a friction modifier. I'd have expected your gearbox to be a bit baulky in cold weather, until it had a bit of a chance to warm up, but maybe you don't have a problem.
