Just been doing a bit of research on 'Marvel Mystery Oil' it appears to be a UCL (Upper Cylinder Lubricant) rather than a preservative/stabiliser, so I have also ordered a bottle of Stabil to go along with the Marvel. A good slug of each in a full tank, 5 mile blast to work it around the system and get the old girl up to temperature, and jobs a good un, then away she goes until March.
