Is it mandatory to use 95 octane fuel for the Xingrui?
2 Answers
Geely Xingrui is equipped with a 2.0T engine across the entire lineup, and the engine's operational conditions require 95 octane fuel. The manufacturer officially recommends using 95 octane gasoline for this vehicle. Although the price difference between 95 octane and 92 octane gasoline is not significant, 95 octane gasoline is more refined and burns more efficiently, which is beneficial for engine maintenance. More details about the Geely Xingrui are as follows: 1. Detail one: Geely Xingrui is a compact sedan under the Geely brand. The dimensions of this car are 4785 mm in length, 1869 mm in width, and 1469 mm in height, with a wheelbase of 2800 mm. The Xingrui is a four-door, five-seater sedan, and all models are powered by a 2.0-liter turbocharged four-cylinder engine. 2. Detail two: The 2.0-liter turbocharged engine in the Geely Xingrui delivers 190 horsepower. This engine can output its maximum power at 4700 rpm, with a maximum torque of 300 Nm available between 1400 and 4000 rpm. The engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. 3. Detail three: The use of an aluminum alloy cylinder head and block reduces the engine's weight, thereby improving the car's fuel economy and handling. The engine is paired with a 7-speed dual-clutch transmission, which enhances gear shifting speed and transmission efficiency. One clutch in the dual-clutch transmission controls the odd-numbered gears, while the other controls the even-numbered gears. 4. Detail four: The front suspension of the Geely Xingrui uses a MacPherson independent suspension, and the rear suspension employs a multi-link independent suspension. The multi-link suspension improves wheel traction, enhancing the car's handling and ride comfort. The multi-link suspension is an evolution of the double-wishbone suspension, where the two arms of the double-wishbone are replaced with separate links.
I've checked the Xingrui's specifications, and the official manual indeed recommends using 95-octane gasoline, which is specifically designed for its turbocharged engine. Lower-grade fuels like 92-octane don't have a high enough octane rating and are prone to causing knocking under high compression ratios, making the engine vibrate like a drum, potentially leading to sudden power drops and increased noise. Long-term use may also damage sensors and pistons, resulting in high repair costs and even affecting the warranty. As someone who's been driving for many years, I've seen quite a few owners trying to save money by using 92-octane, only to experience noticeable performance degradation. That said, it's fine to occasionally use half a tank of 92-octane in remote areas where 95-octane isn't available, but it's best to switch back to 95-octane as soon as possible to ensure smooth engine operation while checking fuel quality to avoid impurities. Regular maintenance of the fuel system during servicing can extend the car's lifespan.
