2021 Mercedes GLA250

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 GLA250.

The 2021 Mercedes GLA250's routine lubrication service is defined by a 5.8-quart engine oil capacity and an approved viscosity range of 0W-20, 0W-30, or 0W-40, giving technicians a climate-calibrated selection while holding the fill volume constant. That 5.8-quart figure is the reference point for every drain-and-fill, and the multi-grade options mean the correct bottle depends on operating conditions rather than a single universal grade. Researchers and service writers should treat this combination as the fixed maintenance baseline for the model year.
