1. An operating-fluid container for a motor vehicle, comprising: a container body having at least two mutually complementary injection-moulded shells of thermoplastic material,wherein the at least two shells include a first shell and a second shell,wherein the first shell and the second shell are welded together in an encircling manner to form a substantially closed hollow body,wherein at least one of the first shell and the second shell has a first layer formed of a first thermoplastic material and a second thermoplastic material, wherein the first thermoplastic material is a different material from the second thermoplastic material,wherein the first thermoplastic material and second thermoplastic material are located in different regions of the first layer, such that the first thermoplastic material is located in a first thermoplastic material region of the first layer not including the second thermoplastic material and the second thermoplastic material is located in a second thermoplastic material region of the first layer not including the first thermoplastic material, and the first thermoplastic material and the second thermoplastic material are disposed lateral to one another in the first layer,wherein the second thermoplastic material includes a fibrous filling,wherein the first layer and the second layer are each injection-moulded. 2. The operating-fluid container according to claim 1, wherein the fibrous filling comprises at least one of glass fibres, carbon fibres, aramid fibres and polyamide fibres. 3. The operating-fluid container according to claim 1, wherein the second thermoplastic material comprises fibres of the fibrous filling embedded in polyethylene. 4. The operating-fluid container according to claim 3, wherein the polyethylene is HDPE. 5. The operating-fluid container according to claim 1, wherein at least one of the first shell and the second shell has a multi-layered wall construction. 6. The operating-fluid container according to claim 1, wherein the first thermoplastic material and the second thermoplastic material have different physical properties and/or different molecular structures. 7. The operating-fluid container according to claim 1, wherein the first layer is an outer layer of the container. 8. The operating-fluid container according to claim 1, wherein at least one of the first shell and the second shell has at least one integrally moulded-on retaining lug and/or retaining cleat. 9. The operating-fluid container according to claim 1, wherein the first layer including the second thermoplastic material is located on a bottom of the container. 10. The operating-fluid container according to claim 1, wherein the first thermoplastic material is an unfilled thermoplastic material. 11. The operating-fluid container according to claim 1, wherein the first layer including the second thermoplastic material is located in at least one corner region of the container. 12. The operating-fluid container according to claim 1, wherein at least one of the first thermoplastic material and the second thermoplastic material is formed of at least one of polyethylene, polypropylene, polyamide, ABS, PTFE, polycarbonate and POM.
