Stephen has given you a comprehensive list.
I would do some research before making rash statements:
Obviously I don't want to use inferior oils,grease etc on her. I have an old Castrol lubrication chart showing me all the various grease,oil points etc,but as you know most of, it not all lubricants won't be available no (sic).
Nothing could be further from the truth.
Almost everything is still available, perhaps not the specific Brands, but the types of lubricants are.
The reason being that lubricants and the items they lubricate are based on the technology of their original era.
Modern engine oils for example, designed for finer tolerances and component materials of the modern computer designed engine, have very different physical attributes to engines of 60+ years ago.
These days, to meet manufacturer's requirements, you have to get different Oil for a Ford from a GM or BMW, because the oil specification is part of the total engine design.
Put modern oil in and you are going to harm the engine.
Gear Oils are similarly era dependant.The materials and tolerances of a modern transmission system are far different to the pre1970s so use 'modern' lubricants at your peril.
Antifreeze/Coolant is also to a totally different technology, in fact there are about 5 different standards now, which are not compatible.
The materials used in a Minor Cooling system will not thank you for using Organic or Hybrid Coolant, it has to be 'Inorganic Additive Technology' or IAT, don't use OAT, HOAT, SiHOAT, PHOAT or any other combination.
Stick with what the Charts say.
