Frequently Asked Questions

Why is an oil change important for a 2018 Mercedes-Benz E-Class?

• Protects the turbocharged 3.0L V6: fresh oil lubricates bearings and turbocharger components, reducing wear on high‑temperature, high‑stress parts.
• Preserves engine performance: clean oil maintains hydraulic lifters, timing components and variable valve timing for responsive power and smooth operation.
• Improves fuel efficiency and emissions: clean oil reduces internal friction so the engine runs more efficiently and within emissions targets.
• Prevents sludge and deposits: scheduled oil changes remove contaminants that otherwise accelerate engine degradation and costly repairs.
• Protects your warranty and resale value: following manufacturer service intervals and having work recorded at a certified dealership helps maintain warranty coverage and vehicle history.

How long does a 2018 Mercedes-Benz E-Class oil change take?

• Typical service time: most dealer oil changes take 45–60 minutes for an express oil service when appointments are available.

• Certified dealership advantage: factory‑trained technicians follow a checklist and can complete inspections and software resets efficiently, often reducing return visits.

• Viscosity and selection: typical viscosities for modern Mercedes turbo V6 engines are 0W‑30 or 0W‑40, but your owner’s manual or dealer service advisor will confirm the correct viscosity for climate and driving style.
