The oil change requires approximately 5.4 liters. You can check the oil level with the dipstick after adding the oil. Here is some information about the dipstick: 1. Purpose of the dipstick: The dipstick is a simple liquid level gauge that directly displays the oil level in the oil pan. The dipstick is not only used to check the level of engine oil but also allows experienced drivers or mechanics to observe the engine's working dynamics. This helps in maintaining the engine, identifying the causes of faults or accidents promptly, preventing further damage, and making quick and accurate judgments. Proper use of the dipstick plays a crucial role in extending the engine's lifespan. 2. Meaning of the dipstick markings: The dipstick measures the static oil level, indicating whether the engine oil volume is within a reasonable range. A standard dipstick has clear upper and lower limits, and the oil level should be between these two marks. Ideally, the level should be around the middle. It's important to note that more oil is not necessarily better. A higher oil level increases engine resistance (since the crankshaft needs to constantly agitate the oil in the oil pan for splash lubrication). Ideally, the oil level should be slightly below the middle mark, as this minimizes engine resistance and fuel consumption while maintaining stable lubrication performance.

I used to drive a new Mondeo and did some research on oil capacity during maintenance. The 2.0T engine requires about 5 liters, while the 1.5T needs slightly less, approximately 4.5 liters. When changing oil, you should check the dipstick marks - the ideal level is in the middle. Too much oil can cause burning, and too little may lead to cylinder scoring. I usually prepare a 5-liter can of full synthetic oil in advance. The 4S shop technician said 5W-30 is most suitable. Remember to check every 7,000-8,000 kilometers - if the oil turns dark or contains impurities, it's time for a change. The oil filter must be replaced every time, otherwise the oil change is wasted. After parking, open the hood and touch the oil pan occasionally - if it's too hot, it indicates heavy engine load, so pay extra attention to oil levels.

The oil capacity for different engine displacements of the new Mondeo does vary. The manual usually specifies a range of 4.5-5.5 liters, but the actual amount needed also depends on how thoroughly the old oil is drained. I once used an oil extractor on my own car's 1.5T engine - after complete drainage, it took 4.7 liters to reach the midpoint on the dipstick. I recommend against using cheaper mineral oil; full synthetic flows better and is more suitable for turbocharged engines. After maintenance, monitor for a day or two - if you see blue smoke from the exhaust or rapid oil consumption, it might indicate seal aging and oil leakage. Also ensure the oil filter matches specifications, as using the wrong one can affect filtration efficiency.

Paying attention to the type of oil is more important than just focusing on the oil level. The new Mondeo recommends 5W-30 full synthetic oil, with approximately 4.5-5 liters required per oil change. The key is regular inspection—I make it a habit to check the oil level monthly by pulling out the dipstick after the car has been parked for half an hour, wiping it clean, reinserting it, and then checking. As long as the oil level is between the marked lines, it's safe. Overfilling the oil can increase fuel consumption and, in severe cases, damage the catalytic converter; too little oil may lead to camshaft wear. In northern winters, pay attention to low-temperature fluidity—0W oil starts faster and provides better engine protection. Remember, engine oil has a shelf life of only six months, so even if the mileage hasn't been reached, it should be replaced after that time.
