Even without a combustion engine or routine oil changes, your 2025 Mercedes Benz EQS 450 requires precise, regular care to deliver its luxurious, cutting-edge performance. Don’t overlook the essential service needs of this advanced BEV — from brake fluid flushes, cabin air filter swaps, to thermal management system checks. Let Costa Oil’s find a Costa Oil near you tool help you keep your EQS 450 running flawlessly, so you can enjoy every drive worry-free.
What Oil Does a 2025 Mercedes Benz EQS 450 Take?
The 2025 Mercedes Benz EQS 450 is a fully electric vehicle and does not require traditional engine oil. Instead, critical regular fluid for your EQS 450 includes brake fluid and thermal management (coolant/antifreeze) fluid. Maintaining these is essential to protect your Mercedes-Benz’s high-voltage battery and regenerative braking system.
- Brake Fluid: Mercedes-Benz recommends a DOT 4+ brake fluid for the EQS 450. Always replace with OEM-spec fluid during brake system service or flushes.
- Coolant (Thermal Management Fluid): Use MB 325.6 approved coolant or equivalent for battery and inverter cooling circuits. Temperature extremes can require more frequent fluid checks — have fluid inspected before summer/winter seasons or every 2 years.
The right brake fluid and coolant ensure peak braking performance and protect critical battery components against overheating — crucial for EV longevity.
2025 Mercedes Benz EQS 450 Oil Capacity
Because the EQS 450 is a battery electric vehicle, it does not have an engine oil reservoir or capacity. However, the brake fluid reservoir typically holds around 1 quart, and your coolant system capacities vary (estimate: 5-7 quarts total across circuits).
Always have technicians inspect fill levels at every scheduled maintenance. Overfilling brake fluid can cause leaks and braking issues, while underfilling coolant may compromise the thermal management of your high-voltage battery. At Costa Oil, our expert team checks all fluid levels to manufacturer spec for every EV service.
How Often Should You Service the 2025 Mercedes Benz EQS 450?
While regular oil changes are not required for the 2025 Mercedes Benz EQS 450, routine EV maintenance is still vital:
- Brake Fluid Flush: Every 2 years, or sooner if fluid is dark or contaminated.
- Cabin Air Filter: Inspect every 15,000 miles or 1 year; replace as needed. Upgrade with a Costa Oil Cabin Air Filter for fresher cabin air.
- Coolant (Battery Fluid): Inspect at least every 2 years, change by 4 years/50,000 miles unless service indicator lights up sooner.
- Tire Rotation: Every 7,500 miles for even wear, crucial due to instant electric torque.
- Windshield Washer Fluid: Fill as needed.
If you drive in extreme climates, urban stop-and-go traffic, or notice warning lights or reduced range, visit Costa Oil sooner to stay ahead of issues. Our location finder can help you book a quick checkup nearby.
Oil Filter for the 2025 Mercedes Benz EQS 450
