A hydraulic system in which hydraulic actuation is applied to move at least one part of a system by a circulating hydraulic fluid, comprising: a) an at least partial immiscibility zone which contains a first hydraulic fluid and a second hydraulic fluid under a condition sufficient for at least partial immiscibility of the first and second hydraulic fluids, the second hydraulic fluid is at least partially miscible with the first hydraulic fluid under a condition suitable for at least partial miscibility and under this miscibility condition the second hydraulic fluid changes a physical property of the first hydraulic fluid; b) at least one hydraulic actuator for providing hydraulic force to the part of the system; c) a mixing zone associated with the at least partial immiscibility zone, the mixing zone for containing the first and second hydraulic fluids which are in a state of at least partial miscibility when there is a condition for at least partial miscibility; and d) at least one pump for transferring the first and second hydraulic fluids which are in a state of at least partial miscibility from the mixing zone to the hydraulic actuator when a condition suitable for miscibility occurs.
