Should the Geely Xingrui use 92 or 95 octane gasoline?

Geely Xingrui should use 95 octane gasoline. Here are the relevant details: Introduction: The Geely Xingrui is built on the CMA platform, which is the first sedan model under this platform. The CMA is a global platform jointly developed by Geely and Volvo. Models built on this platform include the Volvo XC40 and the Lynk & Co series. The Geely Xingrui is positioned to focus on health, power, space, and comfort, and is equipped with a 2.0T engine across the entire lineup. Space: The space layout is very reasonable, and the trunk feels quite spacious. In daily life, the trunk space is sufficient, and the rear seats are also quite roomy. Adults sitting in the back won't feel crowded, and the interior storage compartments are well-designed and plentiful.

I've been driving the Xingrui for two years, and I'll give you the straight answer: you must use 95. The engine has a high compression ratio, and although the fuel cap says 92 is allowed, 95 delivers the best performance. I tried 92 before to save money, and I clearly felt more engine vibration during acceleration, with fuel consumption increasing by about 0.5 liters. Now, spending an extra 20-30 yuan per fill-up gives me smoother acceleration, and in the long run, it's worth it for the protection of the turbo and spark plugs. The anti-knock properties of 95-octane gasoline are better suited for turbocharged engines, especially when climbing hills with the AC on in summer—the engine noise is noticeably quieter.

Last week, I accompanied a friend to the Geely 4S store for a Starry maintenance and specifically asked the technician about refueling. They've encountered several cases in their workshop where the engine fault light came on due to long-term use of 92-octane gasoline. Although the car won't break down immediately, the knock sensor is prone to false alarms, and the onboard computer will automatically reduce power to protect the engine. Using 95-octane gasoline allows for more precise fuel injection and significantly reduces carbon deposits in the combustion chamber. Let's do the math: based on driving 15,000 kilometers a year with an average fuel consumption of 8 liters per 100 kilometers, switching from 92 to 95 octane costs about a thousand yuan more. However, the savings from avoiding carbon deposit cleaning during maintenance easily outweigh this extra cost.

After studying the technical documentation of Geely's 1.5T engine, its direct injection system operates at a pressure of 350bar, combined with a high compression ratio of 13:1. The fuel octane rating directly affects power output efficiency. When using 92-octane fuel, the peak torque RPM is delayed by about 200 revolutions, and turbo response is slightly slower. I've tested both fuel types: with 95-octane, cold starts show significantly less vibration, and idling with AC on at traffic lights doesn't cause RPM instability. Special reminder for frequent highway drivers: 95-octane reduces cylinder temperature by approximately 20 degrees, which is crucial for engine protection.
