Should the Lynk & Co 03 use 92 or 95 octane gasoline?
2 Answers
Lynk & Co 03 should use 95 octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, the Lynk & Co 03 also has this information labeled on the fuel tank cap. You can usually determine the required gasoline grade based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane. If the compression ratio is even higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot solely determine the gasoline grade. High compression ratio engines can also be tuned to use lower octane fuel, as other factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade for the Lynk & Co 03, simply switch back to the correct grade after the current tank is used up. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles designed for lower octane fuel, using higher octane gasoline will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher octane fuel, using lower octane gasoline can cause engine knocking. The significantly lower octane number lowers the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues. The vibrations not only affect driving stability but can also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in extreme cases.
For the Lynk & Co 03, I generally recommend using 95-octane gasoline. From an automotive design perspective, this car features a turbocharged engine with a high compression ratio. 95-octane fuel has better anti-knock properties, which helps prevent engine shaking or power loss caused by ignition knock. If you reluctantly use 92-octane fuel, there may be no immediate issues, but long-term use increases the risk of wear, such as piston damage or increased carbon deposits. The manufacturer's manual and the inside of the fuel tank cap clearly indicate a preference for 95-octane fuel. Don't try to save money only to spend more on repairs later. High-performance cars deserve high-quality fuel—safety is the top priority.
