What to Do If 95 and 92 Gasoline Are Mixed?

Mixing 95 and 92 gasoline occasionally once or twice has little impact. Short-term mixing of different gasoline grades generally does not require special vehicle maintenance. However, long-term mixing of different gasoline grades will affect the service life of the car's ignition system, fuel injectors, and spark plugs, advancing the vehicle's overhaul time. The gasoline grade is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock performance, and its octane number is defined as 100. N-heptane has poor anti-knock performance and is prone to knocking in gasoline engines, so its octane number is defined as 0. If the gasoline grade is 90, it means that the gasoline contains 90% isooctane and 10% n-heptane, which has the same anti-knock performance as standard gasoline.

Installation Position of the New Corolla's Reversing Radar?

Installation position of the new Corolla's reversing radar: Beside the fog light trim, on the front wheel fender. Number of radar probes: Four in the front, four in the rear, totaling eight probes. Function of the Corolla's reversing radar: The radar is a safety assistance system for the car. The rear radar is used when reversing, while the front radar is used to prevent the vehicle from being rear-ended by others. The front radar automatically brakes to prevent rear-end collisions between your car and the vehicle in front. The rear corner and center sensor radars activate when the gear shift lever is placed in the R position, while the front corner radar sensors automatically activate when the gear shift lever is not in the P position (for continuously variable transmission) and the vehicle speed is approximately 10 km/h or lower.

Is the Fuel-Saving Mode in Automatic Transmission Cars Effective?

The fuel-saving mode in automatic transmission cars is effective. During vehicle movement, it comprehensively evaluates and analyzes factors affecting fuel consumption such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine for operation, effectively reducing fuel consumption compared to the normal driving mode. Tips for using automatic transmission: 1. If the vehicle speed is high, remember to use the manual shift mode (if available) to allow the transmission to fully output power. For overtaking or rapid acceleration, shift to the S (Sport) mode; if there is no S mode, gradually upshift. 2. When decelerating, not only apply the brakes but also downshift accordingly. Although modern cars automatically downshift, manual operation by the driver can be more direct and fuel-efficient. 3. Shifting gears (up or down) does not require braking; simply press the button or move the lever to the manual shift position while driving normally for higher power output.

What should I do if the Buick Excelle's body shakes while driving?

If the Buick Excelle's body shakes while driving, it is recommended to perform a four-wheel dynamic balance and four-wheel alignment. If the issue persists after these adjustments, consider replacing the steel rims. Possible causes of body shaking while driving include: 1. Insufficient tire pressure; 2. Incorrect front wheel camber angle data; 3. Loose front lower control arm ball joints, which can also cause lateral swaying; 4. Excessive steering gear clearance, which can also lead to lateral swaying; 5. Loose steering ball joints, which can also result in lateral swaying. A car's wheel is an assembly consisting of the tire and the rim. However, due to manufacturing variations, the mass distribution of this assembly may not be perfectly uniform. When the wheel rotates at high speeds, this can lead to dynamic imbalance, causing the wheel to shake and the steering wheel to vibrate while driving. To prevent or correct this phenomenon, weights are added to the wheel in dynamic conditions to balance the edges of the wheel. This correction process is known as dynamic balancing.

What Causes Frost on the Inside of Car Windows?

Frost forming on the inside of car windows occurs due to a temperature difference between the interior and exterior of the vehicle, which leads to the formation of water vapor inside the car. When the interior temperature gradually drops to match the exterior temperature, the water vapor on the glass freezes. The method to remove frost from the inside is: after the engine's water temperature rises, use the heater to blow warm air onto the windshield until the ice layer melts. Relevant information about car windows is as follows: 1. Introduction: Car windows (car-window) are an essential part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. 2. Window Names: Car windows are categorized by the installation position of the glass: front and rear windshields, side windows, and door windows. The design, structure, and quality of car windows significantly impact the driver's visibility, passenger comfort, aesthetic appearance, and aerodynamic characteristics.
