Should the Lynk & Co 03 use 92 or 95 octane gasoline?
4 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, 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. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline, as other factors such as 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 wrong gasoline grade is occasionally used in the Lynk & Co 03, simply switch back to the correct grade after the tank is empty. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using a higher octane grade 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 recommended to use higher octane gasoline, using a lower octane grade can cause engine knocking. The 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 is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase 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, and in severe cases, cylinder scoring.
I've been driving a Lynk & Co 03, and the owner's manual clearly recommends using 95-octane gasoline because its turbocharged engine has a relatively high compression ratio. The lower octane rating of 92-octane gasoline can easily cause knocking and engine damage during high-speed driving. I tried using 92-octane once, and the car had obvious shaking and roughness during acceleration, along with increased fuel consumption. Now I always stick to 95-octane—even though it costs a few cents more per liter, it saves money in the long run by protecting the engine. It's best to check the label on the fuel cap before refueling to develop good habits and avoid choosing the wrong fuel in a hurry. At the same time, I’d like to remind everyone not to ruin a good car just to save a little money. As they say, engine health is the key to a car’s longevity, and choosing the right fuel ensures a smoother and safer driving experience.
From my perspective, the Lynk & Co 03 must use 95-octane gasoline. The turbocharged design of this car relies on high-octane fuel for stable combustion, while 92-octane fuel may cause premature ignition and engine wear issues. My friend made the mistake of using the wrong fuel and ended up spending a fortune on repairs. I recommend everyone follow the manual and not take risks—saving money isn’t a long-term solution. Also, during routine refueling, take the opportunity to check tire pressure and air filters; proper overall maintenance saves hassle and effort.
I have studied engine technology, and the Lynk & Co 03's turbo system requires 95-octane gasoline. Its high octane rating can prevent knocking under high pressure, which could damage the internals. Using 92-octane fuel increases the risk of performance fluctuations. Choosing the right fuel extends engine life.
