The 2018 GLA 250 requires a synthetic engine oil that meets Mercedes-Benz MB 229.5 (and is compatible with 229.51). Typical viscosities you’ll see recommended are 0W-40 or 5W-40, and the engine’s oil capacity with a filter change is about 5 quarts (approximately 4.7 liters).
The question focuses on the lubrication needs of Mercedes’ compact SUV, which uses a 2.0-liter turbocharged four-cylinder. To protect the engine, maintain performance, and stay within warranty guidelines, you should use an MB-approved synthetic oil that complies with the 229.5 standard. Climate and driving style can influence the exact grade choice, so consult the owner’s manual or a Mercedes service advisor to confirm the correct specification for your vehicle’s VIN and region.
