We have seen considerable confusion about the service products being used in the operation of the Unimog and would like to clear up this matter. Mercedes recommends full synthetic oil in the running gear in Unimog-type vehicles. Special attention is drawn to the fact that only GL4 oils are to be used in the transmission and GL5 in the axles.
Model: 405, 408, 418, 427, 437

Please note these details are also applicable on older models.
Multi-grade oil: Can be used all year round
Single-grade oil: To be used within the recommended temperature limits
If the sulfur content in the fuel is higher than 0.5 – 1.0% by weight, the oil change interval must be halved.
Warning!
Sheet 227.0/.1 is only approved for naturally aspirated engines. It is only to be used when none of the engine oils specified on sheet 228.0/.1/.2/.3/.5 are available.
Engine oils specified on sheet 228.5
Engine oils specified on sheet 228.5 were developed exclusively on DaimlerChrysler’s initiative. These oils represent the highest quality levels worldwide for diesel engines. These are low friction engine oils of SAE grades 10W-40, 5W 40 and 5W-30.
These oils are especially recommended by us as they have favorable effects on the engine’s wear characteristics, fuel consumption and exhaust gas emissions.
Oil fill on reconditioned assemblies
Model series 300/600
Similar to series production major assemblies, reconditioned engines are filled with initial operation engine oil. The first oil change must be carried out no more than 100 service hours later. |
