The Porsche 718 should use at least 95 octane gasoline, but 98 octane gasoline can also be used. Below are the relevant details: 1. The 718 is a mid-engine sports car under the Porsche brand, featuring MacPherson independent suspension for both the front and rear. 2. The 718 is equipped with two engines: one is a 2.0-liter turbocharged engine, and the other is a 2.5-liter turbocharged engine. The 2.0-liter turbocharged engine delivers a maximum horsepower of 300 and a peak torque of 380 Nm, featuring direct fuel injection technology and an aluminum alloy cylinder head and block, paired with a 7-speed dual-clutch transmission. The 2.5-liter turbocharged engine produces a maximum horsepower of 366 and a peak torque of 430 Nm, also equipped with direct fuel injection technology and an aluminum alloy cylinder head and block, matched with a 7-speed dual-clutch transmission.

I've been driving my 718 for over three years and always insist on using 98-octane fuel. Porsche officially recommends 98-octane gasoline due to the engine's high compression ratio, which requires better anti-knock performance. While 95-octane can work in a pinch, 98-octane ensures smoother power delivery, especially during high-speed driving or climbing hills, where the throttle response feels more responsive. From a long-term maintenance perspective, higher-octane fuel helps reduce carbon buildup and protects precision engine components. Some owners try to save money by using 95-octane long-term, only to end up with frequent engine warning lights—repair costs end up being much more expensive. Plus, the 718's fuel tank isn't that large, so the extra cost per fill-up is just a few dozen yuan. It's really not worth skimping on this.

What Causes a Car to Fail to Start After Driving Through a Puddle?

Detailed explanation and solutions for a car failing to start after driving through a puddle are as follows: 1. Bent engine connecting rod: When the vehicle's engine is running, if the water level on the road is higher than the engine's intake system, water can backflow. The water will enter from the air filter to the intake pipe and then into the engine combustion chamber, causing the engine connecting rod to bend. Solution: Replace the engine connecting rod. 2. Spark plug water ingress: If the distributor cap gets wet, it loses its normal ignition function. Water entering the engine air filter element increases intake resistance and causes water to enter the combustion chamber, preventing the spark plug from igniting. Solution: Remove all spark plugs, drain the water from the intake pipe, and then reinstall the spark plugs.

How many points are deducted for running a left-turn red arrow light?

Running a left-turn red light results in a 6-point penalty. Below is additional relevant information: 1. "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": When a motor vehicle violates the prohibition of passing during the red light phase at a signal-controlled intersection or road section, crosses the stop line, and continues to drive, it constitutes running a red light, which incurs a 6-point penalty and a fine. 2. Evidence Collection: When traffic cameras capture the illegal act of running a red light at an intersection, they typically take 3 photos as evidence. One photo shows the vehicle before it crosses the stop line during the red light, and the other two photos show the vehicle continuing to move forward during the red light, crossing the stop line and completely entering the intersection. The 3 photos clearly document the vehicle's movement during the red light phase.

As the capital of Sichuan Province, it is a sub-provincial city, a megacity, and the core city of the Chengdu-Chongqing economic circle. It is designated by the State Council as an important central city in western China, a key national base for high-tech industries, a commercial and logistics center, and a comprehensive transportation hub. 2. Geographical location: Chengdu is located in the southwestern part of China, in the western part of the Sichuan Basin and the heart of the Chengdu Plain. The area features flat terrain, a crisscrossing network of rivers, abundant resources, and developed agriculture.

As an important base for the electronic information industry, it has 30 national-level research institutions, 67 national-level R&D platforms, and 65 universities. In 2019, 301 Fortune Global 500 companies were established here.

Why is there water dripping from the front bottom of the car?

Water dripping from the front bottom of the car is a normal phenomenon designed to drain water and prevent corrosion. The specific reasons are as follows: 1. Drainage holes: The car chassis is equipped with specially designed drainage holes to discharge accumulated water from the vehicle body during rainy or snowy weather. These drainage holes include the engine compartment drainage hole, sunroof drainage hole, door drainage hole, and trunk drainage hole. Among them, the engine compartment drainage hole is usually located on both sides of the front windshield wipers. During rainy days, water accumulated on the sunroof flows along the A-pillar conduit to this area, where it merges with water in the engine compartment inside the fender and is discharged near the wheel mudguard. 2. Air conditioning system drainage: Due to the high temperature inside the car, the cooling system is activated to lower the cabin temperature. At this time, moisture in the hot air inside the car condenses on the surface of the very cold evaporator heat-absorbing fins and is collected by the plastic housing of the evaporator, then discharged out of the car through pipes. The low-pressure pipes of the car air conditioning system are not wrapped with insulation foam, making the pipe surfaces prone to condensing moisture from the air. Water droplets also condense and accumulate at the lowest point of the pipes, eventually dripping down.

What Causes the Tilt When Rolling Up Car Windows?

Detailed explanation and solutions for the tilting issue when rolling up car windows are as follows: 1. Window regulator malfunction: A faulty regulator or aging motor may lack sufficient power, causing abnormal operation when encountering slight resistance. Solution: Replace the window regulator motor. 2. Damaged rubber guide channels: Prolonged vehicle use can cause rubber deterioration and dust accumulation in the window's guide channels, resulting in slow window movement or stopping at certain positions, sometimes with tilting during ascent. Solution: Replace the rubber guide channels. 3. Loose window mounting screws: This condition is often accompanied by unusual noises during window operation. Solution: Tighten the mounting screws.

What are the fire safety requirements for charging sheds?

The fire safety requirements for vehicle charging sheds are as follows: 1. Location: The installation site of the charging station should maintain a certain distance from residential buildings, but not too far, otherwise it would inconvenience residents. This location choice can avoid many unnecessary troubles, and even if an electric vehicle catches fire due to its own malfunction, it will not pose a threat to the personal safety of residents. 2. Style: (1) If the community has a shed, it would be ideal to install the charging pile inside the shed, providing shelter from wind, rain, and sun. If the community does not have a shed, rain shields can be installed on the equipment or sockets to prevent them from getting wet. Of course, charging piles can also be installed in places like underground garages or the first floor of unit buildings. (2) There are many styles of charging piles, such as pillar-type, streetlight-type, wall-mounted, etc. There are no specific requirements for this, as long as they are functional.
