What type of gasoline does the Porsche 718 use?
2 Answers
Porsche 718 uses 95-octane gasoline. This model is equipped with turbocharged engines across the entire lineup, so it requires a minimum of 95-octane gasoline. Gasolines with different octane ratings have varying levels of octane; the higher the octane rating, the greater the octane value, and the better the anti-knock performance of the gasoline. Turbocharged engines operate under high pressure and temperature within the cylinders, necessitating the use of higher-octane gasoline to prevent knocking. Otherwise, the engine is prone to knocking. Extended information: Knocking is an abnormal combustion phenomenon in the engine. When the piston is in the compression stroke, moving upward to compress the air-fuel mixture, the pressure and temperature of the mixture increase. If the gasoline's anti-knock properties are poor, the mixture may ignite prematurely. The burning mixture would then push the piston downward while it is moving upward, leading to reduced engine power and potential engine damage. Severe knocking can even cause connecting rod deformation or piston fracture. Therefore, when refueling, it is essential not only to choose reputable gas stations with high-quality fuel but also to select the correct gasoline octane rating. Avoid small, unreliable gas stations with inferior fuel quality to save money, as prolonged use of such gasoline can lead to increased carbon deposits in the engine. Excessive carbon buildup in the combustion chamber can also contribute to engine knocking.
I've been driving my Porsche 718 for several years, and it definitely requires premium fuel—98 octane unleaded gasoline. This sports car has a high engine compression ratio, and using regular 95 octane fuel can easily cause knocking, reducing performance or even damaging internal components, just like drinking low-quality alcohol can upset your stomach. I always fill up with 98 octane at trusted gas stations, and it feels like the acceleration is sharper, with more responsive throttle. If I'm in a remote area where only 95 octane is available, I opt for reputable brands to ensure quality or add an octane booster as an emergency measure. New drivers should remember to check the owner's manual—it clearly recommends using higher-octane fuel. During maintenance, the mechanic mentioned that long-term use of the wrong fuel can increase carbon buildup, leading to costly and troublesome repairs. In short, caring for your car is like raising a pet—giving it the right fuel keeps it lively.
