How many liters of engine oil does the Cadillac XT4 require?

During maintenance, the Cadillac XT4 requires approximately 4 liters of engine oil for replacement. The recommended oil type is 5W40, using fully synthetic oil, with a replacement interval of one year or within 10,000 kilometers. To ensure normal engine performance and longevity, special attention must be paid to the engine oil in the Cadillac XT4. Additional notes on adding engine oil: Higher viscosity does not necessarily mean better engine protection: High-viscosity oil not only adversely affects overall fuel consumption but also fails to protect the engine adequately. Another function of engine oil is cooling and heat dissipation. Blindly using high-viscosity oil will inevitably weaken the engine oil's heat dissipation performance. Engine oils should not be mixed: The additive components in engine oils from different manufacturers are entirely different. The chemical compositions of these additives vary not only between brands but also within different product lines of the same brand. Mixing oils from two different brands can cause chemical reactions under the engine's high temperatures, such as the formation of flocculants in the oil or increased viscosity.
I've been driving the XT4 for almost three years and have done maintenance four or five times. This is something worth talking about in detail. The factory maintenance manual states that the 2.0T engine requires 5.7 liters of oil, but this figure includes the full capacity with the oil filter. In reality, during oil changes, the mechanics at the repair shop always pour in 5 liters first, then start the engine and let it run for a few minutes before shutting it off. After waiting a while, they check the dipstick. Usually, topping it up to the middle-to-upper mark on the dipstick is sufficient. From my personal experience, it only takes about 5.2 to 5.5 liters to reach that level. Veteran drivers suggest not relying solely on the liter measurement. The most accurate method is to check the dipstick position after the oil temperature normalizes, parking the car, shutting off the engine, and waiting for 5 minutes. Adding too much oil can actually damage the catalytic converter.
Girls, I just had a minor service done on my XT4! Adding engine oil to this car seems complicated, but there's actually a trick to it. The official manual states 5.7 liters, but in reality, you don't need that much. The mechanic told me it's impossible to drain 100% of the old oil—there's always some residue left at the bottom of the oil pan. So, they usually pour in 5 liters first, start the engine to circulate it, then turn it off and slowly top it up while checking the electronic dipstick. Last time, my car only needed 5.3 liters to reach the midpoint. Remember two things: you must check on level ground, and wait 15 minutes after turning off the engine to let the oil settle—only then will the dipstick give an accurate reading. Overfilling will make the engine lose power!
