I also have a 95 4/4 Zetec with very low mileage. I get it serviced by Mike Duncan at Hartlebury and asked him recently (when it had its annual service) whether the gearbox oil should be changed and saying I preferred to err on the side of caution. He suggested leaving it. I was slightly surprised but he knows more about Morgans than I will ever know. But I thought oil degraded with time so was surprised. Interested in comments.
