Frequently Asked Questions

Why is an oil change important for a 2011 Mercedes-Benz S-Class?

• Improved efficiency and emissions: clean oil supports optimal combustion and emissions control, contributing to consistent city/highway mpg and longer component life.
• Protects expensive components: timely oil changes help avoid premature wear to turbos, bearings, and valvetrain, reducing long‑term ownership costs.
