1.5T Mondeo requires approximately 4 liters of engine oil, while the 2.0T Mondeo needs around 5.5 liters. Below are guidelines on how to determine the oil level and precautions for adding engine oil: How to Determine the Oil Level: The accurate amount of engine oil should be determined by the scale lines on the oil dipstick; check the oil level when the car is turned off and parked on a level surface. The oil level should not exceed the upper mark or fall below the lower mark on the dipstick. The optimal oil level is slightly below the upper mark. Precautions for Adding Engine Oil: Do not mix different brands or types of engine oil, as this can lead to the formation of impurities, clogging the vehicle's oil system. This may result in symptoms such as sluggish acceleration, unstable engine idle, difficulty starting, and in severe cases, it can affect the engine's lifespan.

I remember adding about 4.2 liters of oil when I last changed the oil for my Mondeo. The exact amount depends on the engine model and year—mine is the 2.0L version. I suggest you check the owner's manual for precise instructions to avoid underfilling or overfilling, which can cause engine wear. Changing oil is pretty straightforward, and regular maintenance can extend your car's lifespan—typically every 5,000 to 7,500 kilometers. I usually use synthetic oil, as long as the grade matches, like 5W-30. Don’t skimp on cheap oil—saving a few bucks might cost you thousands in repairs. If you’re doing it yourself, stay safe—find level ground and prepare the right tools. If unsure, it’s better to leave it to a professional shop.
