How many liters of engine oil should be added to the Captiva?
2 Answers
The Captiva requires approximately 4.5 liters of engine oil. Engine oil is composed of base oil and additives. Base oils are categorized by quality into Group I, Group II, and Group III base oils, with Group I and II being mineral oils, and Group III being synthetic base oils. There are many types of additives, and the quantity and quality of additives directly affect the API quality grade of the lubricating oil. The functions of engine oil are: 1. To reduce friction and high temperatures; 2. To minimize gas leakage and prevent external contaminants; 3. To protect components from contact with water, air, and acidic harmful gases; 4. To cushion the pressure rise in the engine cylinder; 5. To clean away dirt generated on the working surfaces of components.
My Captiva is the 2.4L version, and I just had it serviced last week. The mechanic said it normally takes about 4.5 liters of 5W-30 oil for an oil change. In practice, it depends on whether the old oil has been completely drained. I always watch the mechanic operate, and after adding 4 liters, I start the engine and let it run for a few minutes, then turn it off and wait five minutes before checking the dipstick. If it's still near the minimum mark, I add another 0.3-0.5 liters until it reaches just above the middle of the dipstick. Never overfill—last time, an apprentice at the repair shop accidentally added half a liter too much, which made the engine feel sluggish and increased fuel consumption. I heard the 3.2L version requires about 5.7 liters, so it's best to check the manual to confirm.
