How much engine oil should be added to a Mercedes GLC?
3 Answers
Due to design reasons, the Mercedes GLC engine requires approximately 6 liters of engine oil. Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, and shock absorption for the engine. Performance of engine oil: The engine oil used in the Mercedes GLC consists of two components: base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while the additives compensate for and improve any deficiencies in the base oil's performance, providing certain new characteristics. Additives are an essential part of the lubricant. Mercedes GLC requires 6 liters of engine oil: Since the Mercedes GLC uses a 9-speed automatic transmission, which offers lower resistance loss and higher transmission efficiency, the engine oil pan is designed to be thicker, thus requiring approximately 6 liters of engine oil. Suitable engine oil for the Mercedes GLC: Choosing engine oil with a higher PAO content can help save fuel consumption while offering advantages in noise reduction and power performance.
The amount of engine oil to add for a Mercedes-Benz GLC mainly depends on the model and engine. Having driven a GLC for several years, I remember my 2.0T GLC300 required about 6.5 liters of oil during each maintenance service. Adding too much oil can lead to abnormal oil pressure or engine overheating, while too little may result in insufficient lubrication. In practice, it's best to first check the oil level using the dipstick, ensuring it's in the middle position. Before adding oil yourself, warm up the engine for a few minutes and measure the level after it cools down for accuracy. I recommend visiting a 4S shop or professional repair center, as they have the right tools and can also check for other issues like oil leaks or blockages, making it worry-free and safe. During regular maintenance, I always remind friends not to randomly add additives or non-branded engine oil to avoid affecting the car's lifespan.
The oil capacity of the Mercedes-Benz GLC typically ranges between 6 to 7 liters. Based on my experience servicing many of them, the GLC300 model requires a standard 6.5 liters, while older models may need slightly less. Before adding oil, ensure the engine is cool and use the dipstick to check the oil level, then gradually top up if it's low. Overfilling can cause foaming, reducing lubrication efficiency and leading to increased fuel consumption or carbon buildup, while insufficient oil accelerates part wear. It's best to use the manufacturer-recommended oil specifications, such as 0W-30, along with regular checks for oil quality changes. DIY oil changes can be error-prone, so it's advisable to have a reliable technician adjust it using professional tools. While driving, pay attention to unusual noises or oil warning lights and address them promptly to avoid major issues.
