Geely Vision uses engine oil with API quality grade: SL grade or above, SAE5W-30 (SAE10W-40 and above for tropical regions). More information about automotive engine oil is as follows: 1. Currently, engine oils on the market can be simply divided into two types based on their base oils: mineral oils and synthetic oils (vegetable oils are not considered due to their scarcity). Synthetic oils are further divided into: full synthetic and semi-synthetic. 2. The main differences between them are: synthetic oils can be used in a wider temperature range, have a longer service life, and are more expensive; for the same oil film requirements, synthetic oils can achieve the goal with lower viscosity, while mineral oils require higher viscosity compared to synthetic oils to meet the same requirements. In the same working environment, synthetic oils have a much longer service life than mineral oils, so they are more expensive, but after comparing the number of oil changes, they are not much more expensive than mineral oils.

I've been driving a Geely Vision for several years. Regarding engine oil, it's generally recommended to use 5W-30 fully synthetic or semi-synthetic oil with an API rating of SN or higher. The manual emphasizes that this type of oil is suitable for the Vision's engine, protecting components under various temperatures and reducing wear during cold starts. In terms of viscosity, 5W indicates good low-temperature fluidity, making it ideal for cold regions; for warmer southern climates, 10W-30 is also acceptable. I've used several brands like Great Wall or Mobil's fully synthetic oils, which offer strong durability and can extend oil change intervals to 8,000-10,000 kilometers. Regularly checking the oil level is crucial—don't wait until it's dirty to change it, as this can lead to increased engine noise and potentially affect fuel consumption. Overall, using this type of oil is the most worry-free option, protecting the car without breaking the bank. It's always safer to consult a professional mechanic during maintenance for advice.

As a frequent long-distance driver, I find that using 5W-30 engine oil for the Geely Vision works perfectly – it's affordable and performs well. Semi-synthetic oil is also a good choice, being cost-effective with each oil change costing around 200 yuan. The key is not to use the wrong oil grade, as it may cause engine overheating or increased fuel consumption. I always make sure to use API SN grade or higher oil, which has fewer impurities and better protects engine bearings. During hot summer months, oil with too low viscosity may become too thin, leading to wear, so checking oil pressure is crucial. Driving habits also influence oil selection: full synthetic oil is more wear-resistant for frequent highway driving, while regular oil suffices for city traffic with frequent stops. The recommended oil change interval is every 5,000 to 7,000 kilometers, and it's a good opportunity to check if the oil filter is clean, which can save significant repair costs. Remember this simple principle for smoother and safer driving.

I've driven the Vision under various road conditions and found that using 5W-30 or 10W-30 engine oil works best, depending on the regional climate. In cold northern areas, 5W-30 provides better protection, while 10W-30 is sufficient in the south. The API grade should be no lower than SN to ensure clean oil and reduce carbon deposits. Synthetic oil offers significant advantages, extending engine life, but it's slightly more expensive. If on a tight budget, mineral oil can be used. Oil change frequency varies by individual; aggressive driving shortens the interval. Choose reputable brands like Shell or KunLun, and always check the oil level after topping up—both too low and too high can harm the engine. In short, matching the oil to your vehicle is most important.
