Mercedes-Benz GLC Engine Oil Guide — MB 229.51 vs 229.6 Malaysia
X253 GLC uses MB 229.51 (5W-30); X254 GLC (2022+) with M254 engine requires MB 229.6 (0W-20). Only fully synthetic oil meeting MB spec should be used — cheaper oils accelerate timing chain wear.
- X253 M274 (GLC 200/250/300): MB 229.51 — 5W-30 full synthetic
- X254 M254 (GLC 200/300 mild hybrid): MB 229.6 — 0W-20 full synthetic
Always verify the oil spec before topping up. The M254 in the X254 integrates a 48V starter-generator with the engine oil circuit — using any oil other than MB 229.6 risks lubrication incompatibility. Cost at 4M Car Care: RM 380–620 for full oil + filter change.
