Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 GLB250.
The 2021 Mercedes GLB250 is a compact luxury crossover that sits between the GLA and GLC in the brand's SUV lineup, built on Mercedes' MFA platform and powered by a turbocharged four-cylinder engine, and it carries 5.8 quarts of engine oil with manufacturer-approved viscosity grades ranging from 0W-20 to 0W-30 to 0W-40 depending on operating conditions; as the second model year of this nameplate, the 2021 GLB250 benefited from the initial refinements made after the model's launch while remaining in the relatively early portion of its production run, which means it carries the typical reliability expectations for a new model introduction that had yet to accumulate the long-term track record that would emerge in subsequent years.
