The 2025 Mercedes Benz EQS 450 SUV is an advanced electric luxury SUV that demands care and precision—including for its oil and fluid maintenance needs. While the EQS 450 SUV uses a fully electric powertrain and does not have a traditional gasoline engine, certain maintenance items such as reduction gear oil may still need periodic checks and servicing. This guide offers a comprehensive overview of the recommended maintenance and oil change procedures specific to the 2025 Mercedes Benz EQS 450 SUV, ensuring your vehicle continues to deliver optimal performance. If you want trusted service, find a Costa Oil near you for a quick, quality oil change experience.

What Oil Does a 2025 Mercedes Benz EQS 450 SUV Take?

Although the 2025 EQS 450 SUV is a fully electric vehicle (EV), the manufacturer recommends regular checks and possible changes for the reduction gear oil, which requires a specific oil viscosity to protect the gear set. For other fluid checks throughout the drivetrain and to support accessory systems, Mercedes Benz recommends:

• 5W-30 (All Temperatures): This viscosity grade covers a wide range of operating temperatures, providing excellent protection for moving parts such as reduction gears or any residual lubrication points.

Mercedes opts for 5W-30 due to its balanced viscosity in both hot and cold climates, ensuring smooth performance year-round. Always confirm with your owner’s manual or technician, but 5W-30 is the default and most widely used option.

2025 Mercedes Benz EQS 450 SUV Oil Capacity

Unlike traditional internal combustion engines, the 2025 EQS 450 SUV does not have a crankcase oil capacity. However, if your service interval includes replacing or topping up the reduction gear oil, it’s essential to use the manufacturer-specified amount. Typically, the reduction gear oil capacity can range from 1 to 2 quarts, but always consult your Mercedes technician.

Always check fluid levels with the proper procedures—a Mercedes Benz specialist can help. Overfilling can cause excessive pressure and possible leaks, while underfilling can lead to inadequate protection. Your dipstick or measurement port should indicate the correct level.

How Often Should You Change the Oil on a 2025 Mercedes Benz EQS 450 SUV?

Electric vehicles like the 2025 Mercedes Benz EQS 450 SUV require less frequent oil maintenance since the main powertrain is electric. Mercedes typically recommends checking and, if necessary, changing reduction gear oil every 40,000 to 50,000 miles. If a synthetic lubricant is used, this interval may extend due to better long-term protection compared to conventional oils.

Signs you should consider an earlier oil change or check include:

• Abnormal noises from the reduction gear
• Visible leaks under your vehicle
• Drivetrain or system warning lights

Always follow your vehicle’s scheduled maintenance for best results and consult with your service advisor if you’re unsure.

Oil Filter for the 2025 Mercedes Benz EQS 450 SUV

While the EQS 450 SUV does not have a traditional engine oil filter, it may use a reduction gear oil filter or strainer. This component helps keep particulates and debris out of the lubrication system, preserving gear longevity and ensuring smooth, quiet operation.

Choosing an OEM-spec filter or equivalent high-quality option is critical for proper fitment and performance. Avoid generic filters that may not match Mercedes’ precise requirements. For premium protection, use certified filters like the Costa Oil Air Filter and OEM-specification cabin filters such as the Costa Oil Cabin Air Filter to maintain clean airflow inside your SUV.
