Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 AMG GT 43.
The 2021 Mercedes-AMG GT 43 presents a clearly defined maintenance profile, with engine oil capacity rated at 9.0 quarts and approved viscosity grades of 0W-20, 0W-30, or 0W-40 depending on operating conditions. This pairing of substantial oil volume and a flexible multi-grade viscosity allowance gives service technicians and researchers a precise baseline for evaluating fluid service intervals and long-term engine condition. As a model-year reference point, the 2021 specifications establish the factory-defined benchmarks against which reliability outcomes and service behavior are consistently measured for this generation of the AMG GT 43.
