The Lynk & Co 03 can use 92 octane gasoline, but the manufacturer recommends using 95 octane or higher. Prolonged use of 92 octane gasoline may damage the engine, so it is advised against. Taking the 2021 Lynk & Co 03 as an example, it is a 4-door, 5-seat compact car with body dimensions of 4639mm in length, 1840mm in width, and 1472mm in height, with a wheelbase of 2730mm and a curb weight of 1395kg. The 2021 Lynk & Co 03 is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 156PS and a maximum power speed of 5000rpm, paired with a 6-speed manual transmission. The front suspension uses a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension.

About the Lynk & Co 03 using 92-octane gasoline, as someone who's repaired cars for over a decade, I'd still advise caution. This car's turbocharged engine was originally designed for 95-octane fuel - 92's octane rating isn't sufficient and can easily cause knocking. Knocking is no trivial matter; short-term you might notice louder engine noise and weaker acceleration, but long-term it could damage piston rings and valves. I've seen many owners opting for cheaper 92-octane, only to require major repairs after 20,000 km, costing thousands. Sure, you might save a few hundred on fuel, but the repair bills could cover three years' worth of 95-octane.

My friend recently picked up a Lynk & Co 03 and considered using 92-octane fuel to save some money. After trying half a tank, he immediately regretted it—the car shook noticeably during acceleration, and fuel consumption was nearly 1L/100km higher than with 95-octane. When he called the dealership, they bluntly warned that engine damage under such conditions wouldn’t be covered under warranty. He rushed to drain the remaining fuel and refilled with 95-octane, instantly restoring the car’s smooth performance. With fuel prices soaring, the potential cost of an engine repair makes sticking to 95-octane the wiser choice.

The fuel cap clearly states to use 95-octane gasoline, and this isn't just printed for fun. The Lynk & Co 03's engine has a high compression ratio, especially when the turbo kicks in, creating significant cylinder pressure. 92-octane fuel's anti-knock performance can't keep up, which may lead to uncontrolled ignition timing. Although the ECU will try to adapt, the power output curve will become less smooth. From my research on engine calibration, long-term use of lower-octane fuel also accelerates carbon buildup and may even clog the catalytic converter.

Some people think there's little difference between 92 and 95 octane fuel, but in reality, using 92 octane in a Lynk & Co 03 might actually cost more in the long run. While 92 octane is a few cents cheaper per liter, the reduced combustion efficiency due to engine knocking can increase fuel consumption by 0.5 to 1 liter per 100 kilometers. When you do the math, the cost per kilometer ends up being similar to 95 octane, plus you're unnecessarily damaging your engine. This is especially true for frequent highway driving - 95 octane keeps the turbo working more consistently, delivering power on demand. While an occasional emergency fill-up with 92 might be fine, don't make it a habit.

Last week, a car owner mistakenly refueled with 92-octane gasoline and drove to our shop. We advised him to avoid aggressive driving. It's generally fine for city driving, but he should stay away from high RPM ranges and not exceed 3,000 RPM. When the tank is down to a quarter, he should refill it with 95-octane fuel to dilute the mixture concentration. If the engine warning light comes on or knocking sounds are heard, he must stop the car immediately. Actually, gas stations now have error-proof designs, and the nozzle diameters are different, so paying attention can prevent misfueling.
