What type of engine oil is suitable for the Geely Vision?

[DeCecilia]

First, for the Vision SUV, it is recommended to use engine oil with an API quality grade of SL or higher; SAE 5W-30 (for tropical regions, use SAE 10W-40 or higher). Below is an introduction to selecting engine oil for the Geely Vision SUV: 1. The choice of engine oil should be based on the requirements of the engine. There is no need to use high-grade oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. Multi-grade oil should be selected whenever possible. Multi-grade oil is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, which are normal.

I've been driving my Vision for over three years and found that 5W-30 full synthetic oil works best. This viscosity is factory-recommended, ensuring smooth cold starts even at -20°C in winter. Just make sure to choose SL grade or higher from reputable brands like Shell Helix Ultra or Great Wall Jijixing - the maintenance manual clearly states it must meet API SN standards. Last time I tried cheaper mineral oil, the engine noise noticeably increased after just 5,000 km. Now I stock up during online flagship store promotions, saving 50% compared to dealership prices. A tip for owners of older 1.5L engines: if you frequently drive on highways, consider switching to 5W-40 for better high-temperature protection.
