Frequently Asked Questions

Why is an oil change important for a 2025 Mercedes-Benz G-Class?

• Maintains optimal lubrication for the twincharged 3.0L inline-6 engine, protecting moving parts and reducing wear under high performance and towing conditions.
• Preserves fuel efficiency and power delivery by preventing sludge and deposits that reduce engine responsiveness and economy.
• Helps manage engine temperature and supports the longevity of turbo and supercharger components that rely on clean, stable oil.
• Keeps emissions systems functioning properly and avoids costly repairs linked to neglected oil changes.
• Performed at Mercedes-Benz of Sudbury, an oil change includes a multi-point inspection and factory diagnostic checks to catch issues early and protect resale value and warranties.

How long does an 2025 Mercedes-Benz G-Class oil change take?

• Typical service time ranges from 45 minutes to 90 minutes, depending on appointment load and whether additional inspections or software maintenance are required.
• Routine oil and filter replacement is efficient, but factory diagnostic checks, brake and tire inspections, and maintenance light resets may extend total time.
• We offer convenient scheduling, and Mercedes-Benz of Sudbury can often provide same-day service or loaner/alternate transportation options to minimize disruption.
• Choosing dealership service ensures technicians use factory procedures and tools, so the job is done right the first time with no callbacks or repeated labor.

How much does an oil change cost for an 2025 Mercedes-Benz G-Class?

• Costs vary based on oil type, filter, and any additional inspections; typical dealership pricing for a premium full-synthetic service is competitive and generally ranges from $249 to $399 for this class of vehicle.
• Mercedes-Benz of Sudbury often costs less than independent shops when you factor in genuine parts, factory-trained technicians, thorough inspections, and bundled service packages that provide immediate and long-term savings.
• Dealership service reduces the risk of premature wear or improper oil selection, lowering future repair bills and protecting warranty eligibility for covered repairs.
• Any repairs or warranty-covered work must be performed at a certified dealership to maintain coverage; our service advisors will explain costs upfront and apply available service specials or coupons.

How often should you get an oil change?

• Mercedes-Benz commonly recommends oil service approximately every 10,000 miles or once a year under normal driving conditions for modern full-synthetic systems; follow the vehicle’s maintenance indicator and owner’s manual for exact intervals.
• Severe driving conditions—frequent short trips, heavy city traffic, towing, or extreme climates—can require more frequent changes, often around every 5,000 to 7,500 miles.
• Our certified technicians will review driving habits and calendar reminders to create a tailored maintenance plan that protects performance and long-term value.
• Keeping a consistent service record at Mercedes-Benz of Sudbury helps maintain warranty coverage and improves resale value by proving factory-trained maintenance history.

What type of oil does an 2025 Mercedes-Benz G-Class take?

• The 3.0L twincharged inline-6 requires high-performance, full-synthetic oil meeting Mercedes-Benz specifications (MB-approved oils). Using the correct specification supports the engine’s turbo and supercharger systems.
• Mercedes-Benz of Sudbury uses only factory-approved synthetic oils and genuine filters to ensure proper viscosity, shear stability, and long-term protection.
• Selecting the correct oil at a dealership avoids the risks of incorrect viscosity or non-approved formulations that can affect efficiency, emissions systems, and warranty coverage.
• Our technicians confirm the exact oil specification for your vehicle and document service to preserve warranty eligibility for any covered repairs.

How much oil does an 2025 Mercedes-Benz G-Class need?

• The 3.0L twincharged inline-6 typically requires approximately 9.5 liters (about 10.0 quarts) of oil when performing a full oil and filter change; actual fill volumes can vary slightly depending on service procedures.
• Mercedes-Benz of Sudbury measures and tops off oil to the precise factory specifications, checks levels after warm-up, and records the exact quantity used for service records.
• Filter replacement, system flushes, or additional maintenance tasks can alter total fluid volumes, so we recommend dealership verification rather than relying on rough estimates.
• Accurate filling by factory-trained technicians helps prevent under- or overfilling, both of which can lead to performance issues or engine damage and affect warranty claims.
