718 Porsche requires 95-octane gasoline. Different grades of gasoline have varying octane ratings, with higher-grade gasoline having higher octane values. Gasoline with higher octane ratings offers better anti-knock performance. The entire Porsche 718 lineup is equipped with turbocharged engines. During operation, the pressure and temperature inside the cylinders of turbocharged engines are relatively high, which is why these engines require higher-octane gasoline. Otherwise, the engine is prone to knocking. The Porsche 718 is Porsche's entry-level sports car, available in two models: the sports coupe Porsche Cayman and the convertible sports car Porsche Boxster. According to Porsche, the vehicle's total weight will be controlled at 1,200 kilograms, 100 kilograms lighter than the previous Boxster model, and it also features a reduction in power.

I've been driving a 718 Boxster for two years and always use 98-octane gasoline. Porsche engines have high fuel requirements, and turbocharged engines need high-octane gasoline to deliver full performance. Once during a business trip, I filled up with 95-octane at a small gas station and immediately noticed slight shaking during acceleration, along with significantly higher fuel consumption. Now, I only refuel at major stations like Sinopec or Shell, and the car runs much smoother. The manual clearly states a minimum of 95-octane, with 98-octane recommended. Long-term use of lower-octane fuel can lead to carbon buildup. Although 98-octane is more expensive, it’s better for engine protection in the long run—repair costs are much higher than fuel savings. For daily commuting, a full tank gives me around 500 kilometers of range.

As an automotive engineer, I believe there are two key points to consider when choosing gasoline for the 718: octane rating and cleanliness. Its horizontally opposed engine has a compression ratio of 11:1, so 98-octane fuel is a must to prevent knocking. The fuel cap has clear labeling inside—just follow that and you can't go wrong. While 95-octane fuel in China is barely acceptable, it will reduce performance, and 91-octane should never be used. Sinopec's 98-octane fuel actually has a higher octane rating than some private companies' 95-octane fuel. A special reminder: don't be fooled by gas stations pushing additives—the best combination is factory-recommended engine oil paired with high-quality gasoline. During each maintenance session, I make it a habit to check the spark plugs' combustion condition. Using the right fuel significantly reduces carbon buildup.

What Causes Excessive Engine Noise in Cars?

Excessive engine noise in cars can be attributed to the following reasons: 1. Insufficient engine oil; 2. Aging engine mounts; 3. Increased carbon buildup in the engine; 4. Deteriorated soundproofing seals. Engine maintenance methods include: 1. Using high-quality engine oil; 2. Using qualified coolant; 3. Regularly cleaning radiator scale; 4. Periodically removing carbon deposits from the engine; 5. Timely replacement of the vehicle's air filter, oil filter, and fuel filter; 6. Checking for damaged spark plugs. The function of an engine is to convert the thermal energy of gasoline into mechanical energy by burning the fuel in a sealed cylinder, causing gas expansion that pushes the piston to perform work.

Can Car Windshield Washer Fluid Freeze?

Car windshield washer fluid can freeze. Once frozen, it can easily cause the reservoir and hoses to crack. Continuously pulling the washer lever to spray the fluid may also lead to motor burnout. Solutions for frozen washer fluid include: 1. Park the car in the sun to use solar radiation to raise the temperature and thaw the fluid; 2. Add some warm water to the reservoir to melt the frozen fluid—avoid using boiling water as it can damage the hoses; 3. Start the car engine, as the heat from the engine can help dissolve the frozen fluid; 4. After the regular washer fluid thaws, replace it with an antifreeze-type washer fluid.

What Causes a Low Clutch?

Clutch engagement being too low is due to air in the clutch system or leaks in the clutch master or slave cylinders. Below are specific details about automotive clutches: 1. Clutch too low: The free travel of the clutch becomes excessively long, while the working travel shortens relatively. This prevents the engine and transmission clutch disc from fully disengaging, keeping the vehicle in a semi-engaged state. 2. Clutch disc too high: This results in longer working travel and shorter free travel, making the vehicle prone to stalling during driving. Additionally, the clutch pedal becomes heavier, requiring more effort from the driver. Prolonged low-speed following can lead to excessive physical fatigue for the driver.
