How many liters of engine oil should be added to a Mercedes-Benz C180?

For a Mercedes-Benz C180, approximately 7 liters of engine oil should be added. After adding the oil, you can check the oil level information. The oil level can be seen through the dipstick, and the optimal level is between the upper and lower marks. If there is too much oil, it can cause carbon buildup between the cylinders and pistons due to flame intrusion, significantly increasing the likelihood of engine knocking. Below are some considerations when selecting engine oil: 1. Choose engine oil based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, and lower-grade oil should not be used in engines with higher requirements. 2. Multi-grade oil is recommended as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker and have lower oil pressure compared to regular oil during use, which is normal.
I've changed the engine oil for my Mercedes-Benz C180 several times myself, and found that it generally requires about 6 liters, depending on the model year and engine type of your car. For example, my 2015 model with the M274 engine takes 6.3 liters. Choosing the right oil is crucial—a full synthetic 5W-40 oil is quite suitable as it effectively protects the engine and reduces wear. Before adding new oil, always check the dipstick to ensure the old oil is completely drained. After adding the new oil, run the engine for a while and measure the level again, keeping it between the min and max marks—too much can damage the seals, while too little can lead to poor cooling or even engine damage. I recommend checking the oil level every 5,000 kilometers yourself, rather than waiting for the warning light, which is too risky. Regularly replacing the oil filter and maintaining a clean oil tank can extend your car's lifespan. If any issues arise, it's safer to have it checked at a professional shop.
As someone who has driven a Mercedes for years, I place great importance on oil maintenance. The oil capacity for a C180 typically ranges between 5.5 to 7 liters, averaging around 6 liters. Using high-quality oil like the manufacturer-recommended 0W-30 can improve fuel efficiency and reduce noise. When adding oil, don't take shortcuts by pouring it all at once—add gradually while checking the dipstick to avoid errors. Insufficient oil can cause the engine to overheat and wear internal components, while too much oil can increase pressure and damage seals. I make it a habit to check the oil level every 3 months, especially before long trips. Remember, the manual is the authoritative guide—don't just rely on others' advice, as Mercedes models vary significantly. Always go to an authorized service center for oil changes to ensure peace of mind—don't risk major damage for minor savings. Regular maintenance is both more cost-effective and safer than emergency repairs.
