What Type of Engine Oil Should the Vision Car Use?
4 Answers
Vision car engine oil requirements vary by season: 1. In summer, use 20W50 or 15W40 API SJ/SL multigrade oil; 2. In winter, use 10W30 or 5W30 API SJ/SL oil. Engine oil, also known as motor lubricant, serves the following purposes: 1. Lubrication and anti-wear; 2. Auxiliary cooling; 3. Cleaning; 4. Sealing and leak prevention; 5. Rust and corrosion protection; 6. Shock absorption. The Vision is a compact SUV under Geely. Taking the Vision X6 as an example, its body dimensions are: length 4546mm, width 1834mm, height 1715mm, with a wheelbase of 2661mm.
I've been driving this Geely Vision for six years and have a lot of experience with oil changes. The official manual recommends 5W-30 synthetic oil as the most suitable, and the engine runs particularly smooth when climbing hills with AC on in summer. Last week's maintenance included a switch to Shell Helix Ultra 5W-30, and the idle noise has noticeably reduced. Don't use oil that's too viscous—40 viscosity might be cheaper but increases fuel consumption by half a liter, which isn't worth it. Remember to change the oil filter at the same time, as roadside shops often skip this step. If temperatures drop below freezing in winter, it's advisable to switch to 0W-30 for quicker cold starts and better protection. For those who enjoy aggressive driving or frequently drive on highways, full synthetic oil offers better high-temperature resistance.
My neighbor, a car mechanic, told me that Geely Vision owners only need to focus on two key points when choosing engine oil: select the viscosity grade 5W-30 and the API service level SP or above. I personally use semi-synthetic oil, which is perfect for a maintenance interval of 7,000 to 8,000 kilometers and costs one-third less than full synthetic oil. Last time, I bought Castrol Magnatec on JD.com for just over 200 yuan, and after changing it, the throttle response became noticeably smoother. Be careful not to buy counterfeit products—always scan the anti-counterfeit code on the oil container to verify authenticity. If your car is over eight years old or burns oil, you can appropriately increase the viscosity to 5W-40. Check the oil dipstick monthly; the ideal oil level is at the midpoint.
Last week during the maintenance at the 4S shop, the technician showed me the engine oil container and explained: The number before the W indicates low-temperature fluidity, and 5W can handle temperatures as low as -30 degrees Celsius. The number 30 is particularly suitable for small-displacement engines like the Vision. The original fully synthetic oil they use comes in gray containers, and after changing it, I noticed much quicker throttle response when driving in the city. If you often drive in dusty areas, remember to shorten the oil change interval. Once I forgot to change it and drove for 12,000 kilometers, and the engine sounded like a tractor. If you notice the oil color darkening or smell a burnt odor, change it immediately.
