What's the Difference Between 92, 95, and 98 Gasoline at Gas Stations?

Here are the differences between 92, 95, and 98 gasoline at gas stations: 1. Different octane ratings: 92 refers to gasoline with 92% isooctane and 8% n-heptane. 95 refers to gasoline with 95% isooctane and 5% n-heptane. 98 refers to gasoline with 98% isooctane and 2% n-heptane. 2. Different vehicle compatibility: 92 is suitable for vehicles with lower compression ratios; 95 is suitable for vehicles with higher compression ratios; 98 is suitable for high-end luxury cars and high-performance sports cars. Additional information: Here are some tips for choosing gasoline grades: 1. 92 gasoline is suitable for ordinary cars with low technical requirements. 2. 95 gasoline is suitable for the vast majority of cars. 3. 98 gasoline is suitable for high-end luxury cars and high-performance sports cars.

What is the flash point of 92-octane gasoline?

The flash point of gasoline varies depending on the brand, batch, and manufacturer. Generally, the flash point of 92-octane gasoline is below 28 degrees Celsius. As long as it falls within the range specified by national standards, it is considered a qualified product. Understanding gasoline grades: Gasoline grades are labeled based on the octane rating. A higher gasoline grade indicates a higher proportion of isooctane. For example, 93-octane gasoline has a higher proportion of isooctane than 92-octane gasoline. The choice of gasoline grade mainly depends on the engine's compression ratio. The higher the compression ratio, the higher the fuel grade should be. E92 gasoline contains 10% alcohol. If you usually use 92-octane gasoline, mixing it with E92 may result in reduced power and shorter driving range. Conversely, if you usually use E92, mixing it with 92-octane gasoline may improve power and extend the driving range. Precautions for refueling: Do not arbitrarily switch to a different gasoline grade. Switching to a lower grade may cause premature combustion, leading to engine knocking. Incomplete combustion can also increase carbon deposits, clogging ducts and nozzles, resulting in reduced vehicle power and increased fuel consumption.

Which gear should an automatic transmission car be in when parked with the air conditioning on?

When parking an automatic transmission car with the air conditioning on, you can place it in the N gear. Alternatively, you can place it in the P gear and engage the handbrake. 1. Common gears: Automatic transmission cars have four main common gears, namely P gear, R gear, N gear, and D gear. The P gear is the parking brake, which allows the braking system to bear most of the force, and then you can shift into the P gear. The R gear is the reverse gear, used when reversing the car. The N gear is the neutral gear, suitable for short-term parking, while the D gear is the driving gear. 2. The difference between P gear and N gear: In reality, there is no significant difference between the P gear and the N gear, except that when you shift into the P gear, a latch engages the gears inside the transmission, preventing the wheels from turning. The N gear does not have this function; if the handbrake is not engaged after shifting into the N gear, the wheels can rotate freely. However, it is important to emphasize that even after shifting into the P gear, you should still engage the handbrake properly, and the P gear should not be used as a substitute for the handbrake.

How to Buy a Fake Driver's License?

You cannot purchase a fake driver's license. Here are the reasons: 1. File Number: The file number is equivalent to the ID number of a driver's license. Each driver's license has a unique file number, just like a person has a unique ID number. Don't underestimate these 12 digits—they can be used to trace which vehicle management office issued the license. 2. Security Thread and Tri-color Fluorescent Fibers: The front and back pages of the license have a windowed security thread, which is a built-in metal strip that is invisible from the outside. The core of the license contains red, green, and blue fluorescent fibers that are visible under sunlight. 3. Consequences: Using a forged or altered motor vehicle driver's license will result in confiscation by the traffic management department of the public security authority, detention in accordance with the law, and a fine ranging from 2,000 to 5,000 yuan. If the act constitutes a crime, criminal liability will be pursued according to the law.

Why Does the Steering Wheel Make Abnormal Noises?

The reasons for abnormal noises in the steering wheel need to be analyzed specifically. Below are the analysis methods: 1. Sound from the turn signal reset: If the turn signal is activated while turning, the noise might come from the rebound clip of the automatic reset mechanism of the turn signal. This situation requires confirmation by the car owner and is considered normal. Sometimes, more than one sound is heard because the steering column has three automatic reset positions per full rotation. If the steering wheel is turned one full rotation, three sounds will be heard. 2. Abnormal noise from the steering column dust cover: If the noise comes from below the steering wheel, it might be due to the steering column dust cover. Lack of lubrication in the dust cover can cause friction noises. In this case, applying some grease inside the dust cover will eliminate the noise. 3. Noise from inside the steering wheel: If the noise originates from inside the steering wheel, it is most likely caused by the clock spring (spiral cable) of the airbag. Remove the steering wheel airbag clock spring, apply some grease, and check if the noise persists. If it does, replace the clock spring as it may be damaged.
