Typically, what characteristics should a normal automotive shock absorber oil have, i.e viscosity, VI, mineral/synthetic, etc. Information on this subject seems to be very "elusive".

Have a look at https://www.amsoil.com/msds/stl.pdf

Thanks for the link Henry, it did help very much.

This is what I was able to determine so far. Apperantly there is no industry standard for shock absorber oil. Most guys seems to recommend Automatic Transmision Fluid. Some Companies does have a "Shock Absorber Oil". They all seem to have the following in common:

Synthetic Hydrocarbon with
High VI: 165 to 210
Low pour point: -36 to -48 degC
Viscosity: 32 to 35 cSt (for motorcycles and extreme temp. conditions this can be as low as 10 to 15 cSt)

I'm going to work with this information, unless there's anything that I've missed or something that anyone would like to add?
