Hi

I have a 10 year old Ford Escort with 92,000 miles on the clock. It's
served me well but I need to get another 12 months/15,000 miles out of
it before I replace it. Over the last 10,000 miles the gearbox has
started to whine, nothing major but the frequency is particularly
annoying, especially at motorway speeds. Is there any additive that
would make an improvement or have I got to live with it? A friend
suggested "molyslip", anyone tried this?
Thanks
Mark
