Hydraulic Fluids

Comparing price and effiency for operating hydraulic systems what is the best weight fluid to operate systems on?
An Iso 46 or ISO 68 fluid would be the most sensible options:
1. These fluids are near the viscosity where hydraulic pumps are the most efficient.
2. Antiwear protection is not quite as good with thinner fluids.
Castrol offer a number of Multiviscosity fluids like Castrol dual range are more efficient over a wider temperature range than monograde fluids.
