Mercedes-Benz E300 requires approximately 4.5L of engine oil. Functions of engine oil: The primary functions of engine oil are lubrication, cleaning, and heat dissipation. In fact, many parts of a vehicle use oil, but the oil that needs to be changed every 5000 kilometers refers to the engine oil. Most people generally use semi-synthetic or fully synthetic oil, while conventional oil is rarely used. Conventional oil is typically used in agricultural machinery, tricycles, and motorcycles. Engine oil change intervals: Conventional oil: 5000 kilometers, Semi-synthetic oil: 7500 kilometers, Fully synthetic oil: can go up to 10000 kilometers before the next maintenance.
As a long-time owner of a Mercedes-Benz E300, I've been using about 7 liters of engine oil for years, though the exact amount depends on the specific model. For my 2018 version, the maintenance manual recommends 6.5-7 liters per oil change. In practice, I always drain the old oil completely and wait half an hour before precisely measuring 6.5 liters with a graduated cylinder. After adding the oil, I start the engine and let it idle for a few minutes to circulate, then turn it off and wait five minutes to check that the dipstick level is between MIN and MAX. Too much oil can overload the engine and cause smoking, while too little leads to insufficient lubrication and accelerated wear - I've seen a friend damage his engine by improper filling, resulting in over 10,000 yuan in repairs. I change the oil every 8,000 kilometers using full synthetic 5W-40 to protect the engine, opting for higher viscosity oil during hot summers. I regularly check the oil level when parked on flat ground to catch issues early, saving money and ensuring peace of mind. Daily driving involves listening carefully to engine sounds - any unusual noise prompts immediate inspection. These small habits significantly extend a car's lifespan.
