Can the Honda Haoying use 95 octane gasoline?

If 92 octane is recommended, then it is not advisable to switch to 95 octane, as using higher octane gasoline is not as beneficial as one might think. Higher octane gasoline does not necessarily improve engine performance. Gasoline octane rating: It is the ratio of the actual anti-knock performance of gasoline to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not always better; the choice of gasoline octane should be based on the engine's compression ratio. Gasoline grade categories: Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 90, 93, 95, and 97 based on the octane value. Gasoline is refined from various gasoline components obtained through petroleum refining, including straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, and is blended with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.

Why can't I pay the retake fee on 12123?

There are many reasons for this situation, among which the most common one is that the mobile phone or server is running unstably. At this time, you can exit the software or restart the phone and try to pay again in a place with smooth network connection. Another possible reason is that the driving test center has not opened the online payment service for retake fees, so you need to go to the test center to pay. The retake fee can be paid on the Traffic Management 12123 platform. Nowadays, exam scheduling, exam fee payment, etc. are all uniformly managed by Traffic Management 12123, and candidates can schedule and pay fees on the platform by themselves. The purpose of this is to reduce the phenomenon of hidden charges by driving schools. On Traffic Management 12123, the retake fee will only appear after you have successfully scheduled the exam. If you have not scheduled the exam, the system will not generate the corresponding service fee. In addition, if you have successfully scheduled the exam but still cannot pay the exam fee, it is likely due to data delay. You can wait a few days and then pay the fee on 12123. Furthermore, after scheduling the exam, even if you have not paid the exam fee, it will not affect the exam. You just need to pay all the fees before obtaining the license.

What Causes All Four Tires to Suddenly Display Low Pressure?

If your vehicle's dashboard suddenly indicates low pressure in all four tires, it is highly likely that the tire pressure monitoring system (TPMS) has malfunctioned, causing confusion in the tire pressure data. Resetting the TPMS should resolve the issue. Another possible reason could be weather-related, as tire pressure fluctuates with temperature changes. If the issue is weather-related, there is no need to worry—once temperatures rise, the tire pressure will increase accordingly. Lower temperatures cause tire pressure to drop, while higher temperatures lead to increased tire pressure. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting drivers to leaks or low pressure to ensure driving safety. There are three common methods of tire pressure monitoring: Direct TPMS: This system uses pressure sensors installed in each tire to directly measure air pressure. The data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure for each tire. The system automatically alerts the driver if the pressure is too low or if there is a leak. Indirect TPMS: When a tire's pressure drops, the vehicle's weight causes its rolling radius to decrease, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius to detect pressure changes. Tire Pressure Monitoring System (TPMS): This hybrid system combines the advantages of both direct and indirect systems. It equips two diagonally opposite tires with direct sensors while incorporating a four-wheel indirect system. Compared to a full direct system, this composite approach reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
