Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 S550.
The 2015 Mercedes-Benz S550 carries an engine oil capacity of 8.5 quarts, with the manufacturer approving three viscosity grades — 0W-30, 5W-30, or 0W-40 — for service refills. That fluid specification is the defining maintenance data point for the model year and frames the basic service footprint owners and technicians work within. For a researcher assembling a model-year reference, the 2015 S550's oil requirement represents the baseline lubrication standard against which surrounding years in the lineup can be measured.
