This is a normal situation. There is no need to worry about it. If the burning is not good in the moment of starting the vehicle, there will be a smell of gasoline, mainly due to the low temperature causing the mixed gas to be unable to burn completely and directly discharged from the exhaust管. It is important to pay attention to what to do when starting a vehicle. First, you need to give the vehicle electricity, and then wait for the vehicle to go through self-inspection. After self-inspection, start the vehicle. After starting the vehicle, let it warm up for 5 to 10 minutes at a standstill to achieve a better driving state. Where can you find the fuel standard of a vehicle? It is located inside the vehicle's fuel tank cap. Just open the vehicle's fuel tank cap, and you can see the fuel label specified by the vehicle. In order to ensure the power output of the engine, the vehicle needs to use the specified fuel according to the label during normal use.
