What are the reasons for not being able to find the vehicle model in Traffic Management 12123?

In addition to checking the appropriate gasoline grade in the car manual, you can also check it on the fuel tank cap, which will also be marked. Usually, the gasoline grade can also be determined based on the engine's compression ratio. However, with the use of some new technologies nowadays, the gasoline grade cannot be determined solely by the compression ratio, as there are other influencing factors besides the compression ratio, such as ignition timing, turbocharging technology, and Atkinson cycle technology. Sports cars generally require 98-octane gasoline, ordinary naturally aspirated engine cars require 92-octane gasoline, and ordinary turbocharged engine cars require 95-octane gasoline. Generally speaking, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally add the wrong gasoline grade, you only need to switch back to the correct gasoline grade after using it up. However, if you consistently add the wrong gasoline grade for a long time, it will have the following effects: For vehicles that recommend a lower gasoline grade, adding a higher grade gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, and the actual feedback experience is reduced power. For vehicles that recommend a higher gasoline grade, using a lower grade gasoline will cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases and it ignites prematurely during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will appear during the upward stroke. This resistance will make the engine run very unstable. If it is only mild knocking, it will just increase noise without obvious damage to the engine. If there is obvious knocking sensation, it indicates the engine's operating condition is already very severe. The vibration not only affects driving stability but also causes abnormal wear of pistons and cylinders, and in severe cases, cylinder scoring.
Recently, while handling the paperwork for my new car, I also encountered a situation where I couldn't find the vehicle model in the Traffic Management 12123 app. There could be several reasons for this. If you're in a hurry when inputting the model name, you might make typos or miss key letters, such as spaces or incorrect capitalization, which can easily lead to no results. Sometimes, the app's database updates slowly, especially for newly released models or imported vehicles, and the system might not have had time to enter them yet—you'll need to wait for an official update. Network issues could also be a factor; unstable signals might cause search failures. Alternatively, the app might have a bug, so try restarting it. I recommend first verifying the accurate model name on the official website and being patient. If it still doesn't work, contact customer service to report the issue to avoid delays. Incomplete account registration information can also affect queries, so remember to complete your profile for more reliable results.
