| Petrol models | |
| Unleaded gasoline no worse than AI-95/A-85, temporary use of unleaded gasoline no worse than AI-91/A-82.5 is possible. In this case, engine power will decrease slightly, with an increase in fuel consumption Do not use fuel additives. They may cause increased wear or engine damage | |
| Diesel models | |
| Summer and winter diesel fuel No.2 or No.1 according to ASTM D975 Do not use ship's (Marine Diesel Fuel), boiler and other diesel fuel. When using diesel fuel with a sulfur content of over 0.5%, change the engine oil every 7,500 km. Winter fuel ensures normal operation down to -20°C. Thanks to preheating the fuel when the vehicle's heating system is on, a vehicle running on winter diesel fuel can, as a rule, be operated without failure at outside temperatures down to -25°C. Do not mix gasoline with diesel fuel. When using summer diesel fuel, as well as at outside temperatures below -15°C, a certain amount of flow improver or kerosene, depending on the outside temperature, should be added to the fuel. Flow improvers can also be used in combination with kerosene. You can obtain a certificate of approved fluidity improving agents at any Mercedes-Benz service station. The proportion of additive, taking into account the outside air temperature, should be minimal. The proportion of kerosene in the mixture should not exceed 50%. Add the additive to diesel fuel until the diesel fuel loses its fluidity due to paraffin emission. Malfunctions due to paraffin emission can only be eliminated by heating the entire fuel system. Mix diesel fuel with kerosene only in the fuel tank. To do this, first pour kerosene into the tank, and then add diesel fuel. After this, the engine must run for some time so that the mixture is distributed throughout the fuel system. Caution! Kerosene additives reduce the flash point of diesel fuel. This increases the danger when handling the fuel mixture. Observe the relevant safety regulations! | |
