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.
