How many liters of engine oil should be added to the Changan CS75?

CS75's 1.5TGDI Blue Whale engine requires 3L of engine oil, while the 1.8T engine requires 4.5L of engine oil. Below is part of the introduction to gasoline filling: 1. After filling the gasoline, the oil level on the dipstick should be at the middle mark. The engine is factory-filled with multi-viscosity grade oil, which can be used in all seasons except in extreme climates. 2. If Changan-certified engine oil cannot be purchased locally, you should choose engine oil that meets the API/ACEA specifications with a quality grade of SN/GF-5 or above and a viscosity grade of 5W-30. However, using these oils may lead to extended engine start-up time, reduced performance, poorer fuel economy, and increased emissions.
I've been driving for over ten years, so I'm quite familiar with oil changes. For the Changan CS75, it depends on the specific engine displacement. The 1.5T engine requires about 4 liters of oil, and if you're replacing the oil filter, a standard 4-liter bottle will suffice. For the 1.8T engine, you'll need 4.5 liters, which means opening an additional small bottle to top up half a liter. The key is to check the oil dipstick. After adding oil, start the engine for a few minutes, then turn it off and check the oil level—it's safest when it's between the upper and lower marks. I've seen beginners add too much oil, causing the engine to feel sluggish. Too much oil increases piston resistance and fuel consumption, while too little is even worse for the engine. The maintenance manual recommends using 5W-30 oil, and I check the oil level with the dipstick every month. Remember, don’t use full synthetic oil before the second service—new cars should use mineral oil during the break-in period.
