How much engine oil should be added to a Mercedes-Benz S350L 6-cylinder engine?

Mercedes-Benz S350L 6-cylinder engine requires approximately 5.8 liters of engine oil. Oil dipstick markings: There are two marks on the oil dipstick, one is the maximum level and the other is the minimum level. The normal oil level should not exceed the maximum mark nor fall below the minimum mark. The oil level between these two marks is considered normal. Method for checking engine oil: After adding oil, start the vehicle and then check the oil level 3 minutes after turning off the engine. This is because when changing the engine oil, the oil filter also needs to be replaced. The new oil filter initially contains no oil, and starting the vehicle allows oil to flow into the filter. Waiting 3 minutes after turning off the engine ensures the oil has drained back into the oil pan, providing a more accurate reading. Remember not to check the oil level on a slope, as the tilted position of the vehicle causes the oil in the pan to tilt as well, resulting in an inaccurate measurement.
As a long-time owner, I've been driving my Mercedes-Benz S350L, a 6-cylinder car, for over a decade. The oil capacity is around 7 liters, but it's best to check the manual or model year for specifics. I make it a habit to perform regular maintenance, such as changing the oil every 10,000 kilometers. Each time, I personally check the dipstick to ensure the oil level is between the min and max marks. Too little oil can cause engine overheating and wear, while too much may lead to leaks or foaming, affecting lubrication. Using the right oil type is crucial—Mercedes recommends 0W-40 full synthetic oil with MB229.5 certification for its excellent temperature adaptability. During an oil change, first drain all the old oil, add 6.5 liters, start the engine for a minute to circulate the oil, then top it up to the perfect level. Safety first—I recommend getting this done at a 4S shop; don't skimp on this small expense to avoid major repairs later.
I pay great attention to car maintenance. For the Mercedes-Benz S350 with its 6-cylinder engine, the oil capacity usually falls within the range of 7 to 7.5 liters, but specifics should be checked in the owner's manual. For example, the M276 engine has a standard capacity of 7 liters, but the actual amount to add should account for residual oil in the filter. So, after adding 6.8 liters, run the engine to allow the oil to circulate evenly before checking the dipstick. Using the right oil is crucial—Mercedes-approved 5W-40 ensures proper lubrication and cleanliness. Never add oil based on guesswork; exceeding the upper limit can increase pressure and damage piston rings, leading to oil leaks. I check the oil level every six months on a flat surface, and measuring after the engine has cooled provides more accurate results. During daily driving, if the oil light comes on, stop immediately to inspect and prevent potential damage.
