Can the Lynk & Co 03 Use 92 Octane Gasoline?
2 Answers
According to the official vehicle manual recommendation, the Lynk & Co 03 should use 95 octane gasoline. It is not suitable for 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, you can also find it indicated on the fuel tank cap of the Lynk & Co 03. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine 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 gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade. A high compression ratio can also be tuned to use lower octane gasoline, as 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 the Lynk & Co 03 occasionally uses the wrong gasoline grade, simply switching back to the correct grade after use is sufficient. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for low octane gasoline, using a higher octane grade will not cause damage, but the increase in octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, manifesting as poorer performance. For vehicles recommended for high octane gasoline, using a lower octane grade can cause engine knocking. A significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. Mild knocking only increases noise without obvious engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.
I've been driving for many years, especially sporty sedans like the Lynk & Co 03. Its engine is turbocharged with high octane requirements - 95 octane fuel is most suitable. 92 octane fuel has too low octane value, which may cause premature ignition in the engine, resulting in knocking phenomenon that sounds like rattling. Prolonged use can damage valves or pistons, leading to expensive repairs. I suggest checking the vehicle manual - it's clearly written in black and white to use 95 octane fuel. Don't risk saving a little on fuel costs - safety comes first when driving. With proper fuel, the engine runs smoother and fuel consumption remains more stable. If you've accidentally filled with 92, switch back to 95 as soon as possible. Short trips might be okay, but long-term use is absolutely not recommended.
