The Trumpchi GS3 uses 5W30 engine oil, which offers excellent low-temperature fluidity, can be used in various weather conditions, and provides superior lubrication. It is one of the most commonly used types of engine oil in the market. The viscosity of engine oil changes with temperature, so special attention must be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C. A higher value means the oil maintains its viscosity better at high temperatures, which can also be understood as providing better lubrication performance under high-temperature conditions. The steps for changing the oil in a Trumpchi GS3 are as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Then, start the engine for about 30 seconds to allow the oil in the main oil passage to drain out. Use a specialized wrench to remove the oil filter. Apply a small amount of oil to the seal of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap on the engine's valve cover. Typically, fill about three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.

I've been driving the Trumpchi GS3 for three years and always use 5W-30 full synthetic oil for . Big brands like Shell or Castrol work perfectly. Cold starts in winter are particularly smooth - it fires right up even at temperatures below -10°C. During summer highway driving, the engine sound remains stable after oil temperature rises. The manual states that either 5W-30 or 0W-30 can be used, with 0W recommended for extremely cold northern regions due to better low-temperature fluidity. Remember to change the oil filter with every oil change. I typically service it every 8,000 to 10,000 km, and regularly check the dipstick color under the hood - when it turns black, it's time for a change. Don't cheap out with no-name oils - a friend of mine used unknown brand oil and ended up with severe engine carbon buildup.

My GS3 is the 1.5T turbocharged version. The technician at the 4S shop said I must use SP-grade full synthetic oil, recommending 5W-30 viscosity. Turbo engines run at higher temperatures and faster speeds, so full synthetic oil better withstands heat and protects components. For naturally aspirated engines, semi-synthetic oil might suffice, but make sure it's at least SL-grade certified. Always check the API certification on the packaging to avoid counterfeit products. Before each maintenance, I check the oil level. If the oil consumption is too fast, it might indicate oil burning or leakage, which needs immediate repair. For new models, follow the manual's recommendations. Older cars with high mileage can try higher viscosity oils like 5W-40.

When selecting GS3 engine oil, viscosity is the key factor. The manual clearly recommends 5W-30. This grade has wide adaptability and can be used in temperatures ranging from -30°C to 40°C. The number 5 before the W represents low-temperature fluidity. Friends in southern regions can also use 10W, which is cheaper. Remember to replace the oil filter when changing the oil, as a dirty air filter can affect intake efficiency. I've compared different brands and found that as long as the oil meets ILSAC GF-6 or ACEA C2 standards, it's decent—no need to blindly trust expensive imported products. To save money after the warranty period, you can opt for semi-synthetic oil, but for turbocharged cars, it's better to stick with full synthetic.

The engine oil requirements for the GS3 vary slightly by year. For post-2022 models, it's recommended to use low-ash 0W-20 oil for better fuel efficiency and environmental friendliness. Older models are safest with 5W-30. Mechanics suggest an oil fill quantity of about 4 liters, not exceeding the MAX line. Some owners reported cold start noises, which improved significantly after switching to 0W oil. For frequent short trips, it's advised to shorten the oil change interval, while highway driving can extend it to 10,000 km. When changing oil yourself, ensure proper disposal of used oil to avoid environmental pollution.

According to 4S store data, Motor officially certifies Total or Idemitsu 5W-30 full synthetic oil. Pay attention to oil certification standards during maintenance - China VI vehicles must use low-sulfur, low-ash oil, look for C2/C3 or SN PLUS markings on the packaging. In extremely cold northern regions, 0W-grade oil is recommended as it significantly reduces cold start wear. I always purchase an extra liter during maintenance for backup, which allows timely top-up when oil burning occurs. For vehicles over three years old, check the valve stem seals as leaks here can also cause excessive oil consumption.
