The type of engine oil for a Vision car varies depending on different conditions: 1. In summer, use 20w50 or 15w40 engine oil; 2. In winter, use 10w30 or 5w30 engine oil. Taking the 2018 Geely Vision as an example, its body structure is a four-door, five-seater sedan with dimensions of 4599mm in length, 1747mm in width, 1482mm in height, and a wheelbase of 2615mm. The fuel tank capacity is 45 liters, and the curb weight is 1210kg. The 2018 Geely Vision features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 109ps, a maximum power of 80kW, and a maximum torque of 140Nm.

















The engine manual of the Vision clearly specifies the oil requirements, and it's essential to follow the standards for reliability. Generally, 5W-30 is recommended as its moderate viscosity ensures both high-temperature lubrication and smooth cold starts. Semi-synthetic oil is advised—it offers better protection than mineral oil and is more affordable than full synthetic. Pay attention to the API certification level on the oil container, with SN grade or higher being the most compatible. Brands like Shell, Mobil, and Castrol offer suitable products—purchase from reputable channels like JD.com's self-operated stores to avoid counterfeit goods. If you frequently drive long distances in summer, consider 5W-40 for better high-temperature stability.

My Vision has been running for over five years, and changing the engine oil is something that really requires attention. The 4S shop uses original semi-synthetic oil with a grade of 5W-30, and it's perfectly fine to change it every 8,000 kilometers or so. If you buy it yourself, pay attention to the ACEA A3/B4 or C3 standards, which are more suitable for direct injection engines. Last time, I bought Shell Helix Ultra online, and the engine noise was noticeably quieter. Of course, in extremely cold winter areas, it's better to use 0W-grade oil for better low-temperature fluidity. Turbocharged models need to be especially careful not to use inferior oil, as it can easily cause carbon buildup. Remember to replace the oil filter every time you change the oil—it only costs a few dozen yuan and isn't something to skimp on.

During , the technician told me the Geely Vision's engine is suitable for 5W-30 viscosity. According to SAE standards, the number 30 indicates high-temperature fluidity, while the number before W represents low-temperature performance. Friends in Northeast China recommend using 0W-30. Engine oils are divided into three categories: mineral oil needs replacement every 5,000 kilometers, semi-synthetic every 7,000-8,000 kilometers, and full synthetic can last up to 10,000 kilometers. Pay attention to the ILSAC certification mark on the oil container; those with GF-6 markings are more fuel-efficient. I've recorded fuel consumption data, and using full synthetic oil indeed saves 0.5 liters per 100 kilometers. Don't buy off-brand oil filters; Mann or Mahle brands are reliable in quality.

Auto repair shops often encounter cases of engine cylinder scuffing caused by using the wrong oil. For Vision owners, remember three key points when changing oil: First, always use 5W-30 oil that meets the VCC RBS0-2AE standard specified in the manual, with full synthetic being the best choice. Second, check the dipstick - the oil level should be slightly above the middle mark; overfilling increases crankshaft resistance. Finally, don't exceed the oil change interval of six months or 10,000 km, and change even sooner if you primarily drive short distances. For China VI emission standard vehicles, low-ash oil must be used to avoid clogging the GPF (Gasoline Particulate Filter). I've seen cases where using the wrong oil caused vehicles to fail annual emissions inspections.

Last month I changed the oil on my Vision by myself, and the process was quite straightforward. First, park the car on level ground and let the engine cool for ten minutes, then open the hood to locate the oil drain plug and oil filter. Use a 17mm wrench to drain the old oil (remember to place a pan underneath), and remove the old oil filter with a wrench. Apply a layer of new oil to the rubber seal of the new filter before tightening it. When pouring in the new oil, use a funnel to avoid spills. A four-cylinder engine typically takes around 3.5 liters of oil—check the dipstick to ensure it doesn’t exceed the maximum mark. When selecting oil, pay attention to certifications; for example, low-ash oils with ACEA C2/C3 certification are better suited for China-6 vehicles and also help protect the catalytic converter.
