[Mgs] Shock Oil

They are hydraulic shocks, so use hydraulic oil.  Hydraulic jack oil 
is just a conveniently available package for hydraulic oil.  Most 
"generic" hydraulic oil, unless otherwise labled, is 20-weight or 
20W20 with some non-foaming addatives.  20-weight is as originally 
specified, and you should not deviate too far from this 
spec.  30-weight will make the shocks considerably stiffer, maybe 
undesireable for street use.  50-weight might seem like infinitely 
stiff and could result in broken internal parts.  I seem to recall 
that Peter Caldwell who rebuilds the shocks may use 20-weight motor oil.
