Mercedes-Benz S400 Hybrid Engine Oil Specs

The Mercedes-Benz S400 Hybrid was produced from 2010 to 2013. This model typically uses 5W-40 full synthetic engine oil — a specification common to most Mercedes-Benz S40-series vehicles.

Selecting the correct oil viscosity for your Mercedes-Benz S400 Hybrid is essential. Using a grade that is too thin reduces protection at operating temperature, while too thick an oil impairs cold-start flow and reduces fuel economy. Always match the exact grade shown for your specific model year.

The recommended oil change interval for the Mercedes-Benz S400 Hybrid is every 10,000 miles or 12 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.

When servicing your Mercedes-Benz S400 Hybrid, always replace the oil filter at every oil change. Using a premium filter — such as the Mann or Mahle filters specified for European engines — ensures proper oil pressure.

Oil change costs for the Mercedes-Benz S400 Hybrid at a US dealership or independent European specialist typically range from $120 to $200 for a full synthetic service. DIY oil changes cost approximately $30–$65 in parts (oil + filter) and take about 30 minutes with the right tools.

Always consult your vehicle's owner's manual to confirm the exact specification for your specific trim and engine variant, as some Mercedes-Benz S400 Hybrid configurations may have different requirements.
