Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 CLS450.
The 2019 Mercedes CLS450 is a luxury vehicle whose maintenance specifications merit close study, headlined by a 9.0-quart engine oil capacity and compatibility with 0W-20, 0W-30, and 0W-40 viscosity grades. The broad viscosity range affords technicians and owners flexibility across varying operating conditions, while the substantial oil volume reflects a powertrain with greater complexity and capacity than that of a typical passenger car. For researchers evaluating this model year within the CLS lineage, these demanding lubrication requirements signal that meticulous, spec-compliant maintenance is central to preserving long-term reliability.
