W205 Oil Journey (1) - Major Oil Brands - Oil Finder Tools
I personally prefer to find recommended oils from the official websites of manufacturers located in the vehicle's country of origin.
For example, since the W205 is produced by Mercedes-Benz in Germany, I look for recommendations from prominent German oil manufacturers.
Before searching, visit LastVIN.com and enter your VIN to identify your specific model and engine version code.
(This will be very helpful when using the Oil Finder tools below.)

Oil Change Interval Planning
In Germany, engine oils are typically categorized into 15,000 km and 25,000 km drain intervals.
However, the maintenance intervals recommended in Taiwan are often only 2/3 of those abroad. If an oil is rated for 15,000 km in Europe, the local dealer might suggest a 10,000 km interval. Based on this ratio, a "long-life" oil rated for 25,000 km should be changed at approximately 16,600 km in Taiwan.
Conclusion: Considering that Taiwan's driving conditions and climate are among the harshest globally, a 15,000 km interval is a safe and recommended middle ground.
Approvals and TBN Metrics
You may notice that while some oil manufacturers suggest a 15,000 km interval for W205 using both MB 229.51 and 229.5 approvals, it is rare to see MB 229.51/229.52 approvals for the 25,000 km ultra-long intervals.
The main reason is the TBN (Total Base Number), which measures the oil's ability to neutralize acids:
| Approval Standard | TBN Value | Characteristics |
|---|---|---|
| MB 229.5 | ≥ 10 | High TBN, strong acid neutralization, suitable for long intervals. |
| MB 229.51 / .52 | ≈ 6 | Lower TBN, typically designed to protect emission systems (DPF). |
Therefore, oils intended for extended mileage usually feature a higher TBN to ensure long-term engine protection.
⚠️ Important Reminder: Extended drain intervals MUST be paired with "Long-Life" filters with increased capacity. Use generic filters at your own risk.
