2. A fluid reservoir system as claimed in claim 1 in which said one or more latches is separate from said self-sealing couplings; is biased to a locking position to thereby retain said container in fluidic communication with said vehicle engine fluid circulation system and is remotely operable to disconnect said container from said vehicle engine fluid circulation system.

3. A fluid reservoir system as claimed in claim 1 in which said self-sealing couplings comprise at least one latch of said one or more latches which is biased to a locking position to thereby retain said container in fluidic communication with said vehicle engine fluid circulation system and is remotely operable to disconnect said container from said vehicle engine fluid circulation system.

4. A fluid reservoir system as claimed in claim 3 which further comprises at least one further latch which is separate from said self-sealing couplings; is biased to a locking position to thereby retain said container in fluidic communication with said vehicle engine fluid circulating system and is remotely operable to disconnect said container from said vehicle engine fluid circulation system.

5. A fluid reservoir system as claimed in claim 1 in which said at least one actuator comprises an elongate actuator member which comprises first and second ends and extends between said first and second ends of said container; and said one or more latches comprises a collar which is operably connected to said first end of said elongate actuator member by a transverse actuator member.

6. A fluid reservoir system as claimed in claim 5 in which said at least one actuator comprises a single elongate actuator member extending from said first end of said container to said second end of said container; all of said one or more latches comprise a collar; and all of said collars are operably connected to said first end of said single elongate actuator member by a transverse actuator member.

7. A fluid reservoir system as claimed in claim 5 in which said actuator comprises a lever for operating said actuator, where the reservoir system comprises a handle for carrying the system and the lever is pivotably or slideably mounted on the handle.

8. A fluid reservoir system as claimed in claim 1 in which said actuator comprises at least one electromagnetic member that operates at least one latch of said one or more latches.

9. A fluid reservoir system as claimed in claim 1 in which said container comprises a filter for filtering fluid.

10. A fluid reservoir system as claimed in claim 1 in which at least one of said ports comprises a non-return valve.

11. A fluid reservoir system as claimed in claim 10 in which said at least one fluid outlet port comprises a non-return valve.

12. A fluid reservoir system as claimed in claim 1 in which said container contains engine lubricating oil composition.

13. A fluid reservoir system as claimed in claim 12 in which said engine lubricating oil composition is a lubricating oil composition for an internal combustion engine.

14. A fluid reservoir system as claimed in claim 12 in which the engine lubricating oil composition is a lubricating oil composition for an electric engine.

15. A fluid reservoir system as claimed in claim 1 in which said container contains a heat exchange fluid for an electric engine.

16. A fluid reservoir system as claimed in claim 1 when said container is in fluidic communication with the fluid circulation system of a vehicle engine.

17. A fluid reservoir system as claimed in claim 16 in which said corresponding ports on said vehicle engine are self-sealing ports.

18. A method of supplying fluid to a vehicle engine comprising a fluid circulation system, which method comprises connecting to said fluid circulation system, a fluid reservoir system as claimed in claim 12 .

19. A fluid reservoir system for an apparatus, which the apparatus comprises a fluid system, the reservoir system comprising a container for fluid, in which the container comprises at least one fluid port, and in which, said at least one port comprises a self-sealing coupling that connects to a corresponding coupling on the apparatus to thereby connect said container in fluidic communication with the fluid system of the apparatus and in which the reservoir system comprises one or more latches that retains said container in fluidic communication with said apparatus fluid system and is remotely operable to disconnect said container from said apparatus fluid system and in which the reservoir system comprises at least one actuator which is connected to said one or more latches and that operates said one or more latches; said container is elongate; said at least one port is located at a first end of said container; and said at least one actuator is operable at a second end of said container distal from said at least one port.

20. A fluid reservoir system as claimed in claim 6 in which movement of said at least one actuator in a direction perpendicular to said second end of said container causes said single elongate member to act through said transverse actuator member on each of said one or more latches thereby operating each of said one or more latches and disconnecting said container from said fluid circulation system.

21. A fluid reservoir system for an apparatus, which the apparatus comprises a fluid circulation system, the reservoir system comprising a container for fluid, in which the container comprises at least one fluid inlet port, at least one fluid outlet port and at least one vent port and in which, each of said ports comprises a self-sealing coupling that connects to a corresponding coupling on the vehicle engine to thereby connect said container in fluidic communication with the fluid circulation system of the engine and in which the reservoir system comprises one or more latches that retains said container in fluidic communication with said vehicle engine fluid circulation system and is remotely operable to disconnect said container from said vehicle engine fluid circulation system and in which the reservoir system comprises at least one actuator which is connected to said one or more latches and that operates said one or more latches; said container is elongate; said inlet, outlet and vent ports are located at a common first end of said container and extend from said first end of said container in a respective direction; said at least one actuator is operable at a second end of said container, distal from said ports; and said at least one actuator extends from said second end of said container to said first end of said container in a second direction that is parallel to the respective directions of said inlet, outlet, and vent ports.
