How many liters of engine oil does the Mercedes-Benz E300 require?

The Mercedes-Benz E300 requires 7 liters of engine oil. The new Mercedes-Benz E300 uses engine oil with the specification 5W40. If you want to change the oil during later maintenance, you can choose from brands like Shell, Castrol, Great Wall, Tongyi, or Tianshan. The viscosity of engine oil changes with temperature, so special attention must be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Mercedes-Benz E300 is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops dripping. Start the engine and let it run for about 30 seconds to allow the oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply some oil to the seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container. Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
I understand that the oil issue for the Mercedes-Benz E300 is quite important. Generally, depending on the model year and engine type, the oil capacity ranges from around 6 to 7 liters. For example, the common 2019 2.0T engine requires approximately 6.5 liters. However, I recommend first referring to the owner's manual for the official figures, as different displacements can affect this. Overfilling may cause foaming, leading to poor lubrication, while underfilling can result in engine overheating and faster wear. When changing the oil, add the new oil slowly and use the dipstick to check the oil level—midway is ideal. Also, choose Mercedes-certified oil types to ensure compatibility, and avoid using cheap, off-brand oils that could affect performance. Regularly confirming the correct oil level during maintenance is crucial for extending your car's lifespan.
