Using the correct oil standard is essential to prevent engine damage.
- Suitable Oil Viscosity
Oil viscosity depends on weather conditions and engine type. Mercedes-Benz generally recommends the following viscosities:
- 0W-40: Ideal for colder climates.
- 5W-30: Ensures optimal performance in moderate climates.
- 10W-40: Best suited for older engines and warmer regions.
- Recommended Brands
Several reputable global brands produce oils that meet Mercedes-Benz specifications. These include:
- Mobil 1: Compliant with MB 229.5 and MB 229.51.
- Castrol EDGE: High-performance oil for advanced engines.
- Shell Helix Ultra: Fully synthetic and suitable for both gasoline and diesel engines.

- Oil Quantities for Various Mercedes-Benz Models
The required oil quantity varies depending on the model and engine type. The table below provides approximate amounts:
| Model | Engine Type | Oil Quantity (Liters) |
| C-Class (C180, C200) | 4-cylinder gasoline/diesel | 5.5 – 6 |
| E-Class (E300, E350) | 6-cylinder gasoline/diesel | 6.5 – 7.5 |
| S-Class (S500, S63 AMG) | 8-cylinder gasoline | 8 – 9.5 |
| GLC (GLC300) | 4-cylinder gasoline/diesel | 5.5 – 6 |
| AMG (C63, G63) | 8-cylinder turbocharged | 8.5 – 9.5 |
For precise measurements, always consult the car manual or a professional technician.
- Oil Replacement Schedule
The frequency of oil changes depends on the engine type and driving conditions. General guidelines are as follows:
- Standard gasoline engines: Every 10,000 to 15,000 kilometers or annually.
- Diesel engines with DPF: Every 10,000 kilometers or annually.
- AMG models: Every 7,000 to 10,000 kilometers for optimal protection.
- Harsh conditions (urban driving, extreme temperatures): Shorter intervals (around 8,000 kilometers).
- Steps for Changing Engine Oil
Follow these steps for a successful oil change:
- a) Preparation
- Tools required:
- Suitable engine oil
- New oil filter
- Drain plug washer (if needed)
- Container for used oil
- Warm the engine for a few minutes to facilitate oil flow (avoid overheating).
- b) Draining Old Oil
- Unscrew the oil drain plug and collect the oil in a container.
- Remove the old oil filter and replace it with a new one.
- c) Adding New Oil
- Pour the new oil slowly.
- Check the oil level using the dipstick.
- d) Final Check
- Start the engine and recheck the oil level.
- Ensure there are no leaks around the drain plug and filter.
- Key Tips for Oil Changes
- Digital Oil Monitoring System: Newer models have a digital display to provide accurate information about oil levels and condition.
- Using ASSYST PLUS Software: This system in modern cars indicates the appropriate time for an oil change.
- Authorized Dealerships: If unsure, have the oil changed at authorized Mercedes-Benz service centers.
- Recycling Used Oil
Used oil should be taken to certified recycling centers to prevent environmental pollution.
- Conclusion
Choosing the right engine oil and adhering to replacement schedules are vital for the performance and longevity of Mercedes-Benz vehicles. By following the recommendations outlined in this guide, you can ensure optimal car performance while minimizing maintenance costs. For detailed information, always refer to the car manual or consult an authorized dealership.
I believe that using the appropriate oil at the correct mileage intervals increases the engine’s lifespan and enhances its efficiency.
