What brand is the original Mercedes-Benz transmission oil?
2 Answers
Mercedes-Benz original transmission oil is a DCT-specific oil imported from Germany, with the product part number A00198985309. Mercedes-Benz transmission oil is generally recommended to be replaced every 3 years or 60,000 kilometers, whichever comes first. Different models have different replacement cycles. Below are the replacement cycles for transmission oil: Manual transmission: Manual transmission oil is generally recommended to be replaced every 3 years or approximately 100,000 kilometers. Automatic transmission: Automatic transmission oil is generally recommended to be replaced every 2 years or approximately 40,000 kilometers. Continuously variable transmission (CVT): CVT oil is generally recommended to be replaced every 2 years or approximately 60,000 kilometers. The methods for replacing transmission oil are as follows: Unscrew the drain plug at the bottom of the transmission to drain the oil before refilling. Remove the transmission oil pan directly to drain and refill the oil: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: Dynamic oil replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.
I've been driving Mercedes-Benz cars for over a decade. The original transmission fluid is usually from Petronas, a brand that has a long-term partnership with Mercedes-Benz, providing custom-formulated fluids specifically for their transmissions. Every time I go for maintenance, the 4S dealership insists on using this brand. A single change can last about 70,000 to 80,000 kilometers, which is quite durable. If you try to save money by switching to a no-name brand, it may not only affect the smoothness of gear shifts but also accelerate wear on internal components. Repairs in such cases can cost several thousand dollars, making it really not worth it. Additionally, the color of the transmission fluid is a key indicator—fresh fluid is light red, and if it darkens or turns black, it's time for a check-up. I recommend having a professional mechanic inspect it regularly to ensure safe and smooth vehicle operation.
