Gasoline can be classified into several types based on their grades, mainly including 90, 93, 92, 97, and 98. The primary difference lies in their application areas. Regular cars typically use 90 and 93 gasoline, while high-end sports cars and sedans mostly use 97 and 98. Below are the differences between 92 and 98 gasoline: Applicable Compression Ratio: Cars with a compression ratio between 8.5 and 9.5 use 92 gasoline; those with a compression ratio greater than 9.8 use 98 gasoline. Octane Level: 92 gasoline has a lower octane rating than 98 gasoline, meaning 92 gasoline contains 92% isooctane, while 98 gasoline contains 98% isooctane.

How to Replace the Battery of a Tire Pressure Monitor?

Tire pressure monitor battery replacement method: 1. Prepare a wrench tool, then use the wrench to unscrew the external sensor; 2. Remove the anti-theft washer upwards; 3. Place the sensor on the disc-shaped opener, unscrew the shell. If it's too tight to remove, you can wrap the outer part of the disc with a cloth and then use force to open it; 4. Install the new battery, screw the shell back on, and put back the anti-theft washer that was just removed; 5. Reinstall the sensor onto the valve stem. Tire pressure monitoring is divided into three types: direct tire pressure monitoring, indirect tire pressure monitoring, and composite tire pressure monitoring. Through the tire pressure monitoring system, car owners can always keep track of tire conditions and prevent blowouts. Excessive tire pressure will reduce the shock absorption effect of the tire, thereby increasing the burden on the vehicle's shock absorption system; if the tire pressure is insufficient or uneven, it can easily cause brake deviation, thereby increasing the wear of the suspension system.

What is the maximum speed of a tank?

The maximum speed of a tank is 180KM/H, while the legal maximum speed limit is 120KM/H. Maximum speed: Refers to the maximum driving speed that a vehicle can achieve under windless conditions on a level, good-quality asphalt or concrete road surface. The maximum speed mentioned here is data provided by the manufacturer, for reference only, and does not represent PCauto's actual measured data. Testing method for maximum speed: The last 500 meters of a 1.6-kilometer test section are used as the testing area for maximum speed, with four round trips conducted to obtain an average value. The maximum speed differs from the theoretical maximum speed (which refers to the best performance achieved by the engine under optimal conditions, limited to theory). For some high-performance vehicles, manufacturers often limit the vehicle's maximum speed through technical means (such as electronic speed limit functions) to protect the engine or comply with traffic regulations. For example, the Mercedes S600, when the electronic speed limit is removed, can exceed the restricted 250km/h and reach 300km/h or even higher.

What causes the engine malfunction light to suddenly come on and the car to shake when accelerating?

Reasons for the engine malfunction light suddenly coming on and the car shaking when accelerating: 1. Damaged spark plugs, where the wear of the spark plug electrode gap leads to insufficient spark ignition, causing incomplete combustion of the air-fuel mixture and resulting in shaking during acceleration; 2. Poor quality gasoline, leading to inadequate atomization by the fuel injectors and incomplete combustion of the air-fuel mixture in the cylinder, which can also cause idle shaking; 3. Faulty oxygen sensor, where damage to the oxygen sensor or its connector, or loosening, can cause the air-fuel mixture to be too lean or too rich, triggering the malfunction light; 4. Faulty mass air flow sensor, which measures the amount of air intake and converts it into an electrical signal sent to the Engine Control Unit (ECU), indirectly allowing the ECU to determine the amount of fuel to inject. If the mass air flow sensor or its circuit malfunctions, the ECU will not receive the correct air intake signal, leading to improper fuel control and causing the air-fuel mixture to be too lean or too rich, preventing the engine from operating normally.

How to Clear the Maintenance Reminder on a 2017 Focus?

First, insert the vehicle key and start the car. Then locate and hold the button on the lower right side of the instrument panel until you hear a "ding" sound. Next, press the OK button on the multifunction steering wheel to clear the maintenance reminder on the dashboard. Here are some relevant details: 1. When a vehicle is sold or after maintenance, a maintenance reminder is usually set. When the vehicle's mileage or time reaches the maintenance standard, the maintenance light will illuminate, indicating that the vehicle should be serviced as soon as possible to ensure optimal operating conditions. 2. If the dealership forgets to set a new maintenance mileage after servicing, you can refer to the vehicle's manual to find the method for resetting the maintenance mileage. If you are unable to perform the operation, you can also take the car to the dealership or an auto repair shop and have a professional mechanic reset the maintenance light, thereby clearing the maintenance mileage reminder.

What Causes the Idle Speed of Buick Excelle to Fluctuate?

The reasons for fluctuating idle speed are as follows: 1. Dirt from the air and sludge from gasoline can easily cause the throttle to become dirty and the idle air control valve to malfunction. 2. Excessive carbon buildup can lead to valves not sealing properly, poor fuel injector atomization, and insufficient combustion. 3. A clogged exhaust pipe can result in poor exhaust flow. 4. Air leaks can cause insufficient vacuum. 5. Aging wiring or issues with the ECU (this phenomenon is unlikely to occur in the short term). It is recommended that owners avoid installing additional devices on the vehicle. 6. Insufficient cylinder compression due to natural wear (this phenomenon is unlikely to occur in the short term).

How many liters of fuel can a Jetta hold?

A Jetta can hold 55 liters of fuel. Fuel tank capacity: Generally, small cars have a fuel tank capacity of 35-45 liters, while mid-size cars have a fuel tank capacity of around 55-75 liters. A full tank usually allows a car to travel about 500 kilometers. The size of the fuel tank depends on the car's displacement and fuel consumption—larger fuel tanks are for cars with higher fuel consumption, and smaller tanks are for those with lower consumption. In China, the fuel tank capacity is regulated to be 95% of the rated value, but in practice, the actual capacity is usually larger than the nominal capacity, so there's no need to worry about the fuel tank being smaller than expected. Fuel tank capacity measurement unit: Internationally, the standard unit for measuring fuel tank capacity is liters (L). Different countries also have their own standards for fuel tank capacity. In China, the fuel tank capacity is regulated to be 95% of the rated value, but in practice, the actual capacity is usually larger than the nominal capacity, so there's no need to worry about the fuel tank being smaller than expected.
