At what mileage should fuel additives start to be used?

Fuel additives should start to be used at 20,000 kilometers. Mileage for using fuel additives: Fuel additives are unnecessary for new vehicles with less than 20,000 kilometers. For vehicles exceeding 20,000 kilometers, they should be added as needed, typically one small bottle per tank of fuel. Long-term use of fuel additives can be harmful to the engine. Excessive use can increase carbon deposits in the combustion chamber, and prolonged overuse may even lead to engine knocking, detonation, and worsened vehicle emissions. Precautions for using fuel additives: New vehicles are not recommended to add fuel additives because they haven't been driven much, and their operating conditions are usually good, with no serious carbon deposits, so additives are unnecessary. Frequent use of fuel additives is not advisable, as it can lead to oil sludge and gum formation, increasing carbon deposits in the combustion chamber. They should be added based on the vehicle's usage. For severe carbon deposits, manual cleaning is still required; fuel additives are not a miracle solution. For vehicles with severe carbon deposits, manual treatment is necessary, as fuel additives cannot completely remove them. For older vehicles, the oil filter should be cleaned or replaced before adding fuel additives. Use fuel additives cautiously and add them reasonably according to the vehicle's condition.

What does it mean when the electric car charger shows a yellow light?

Electric vehicle charging showing a yellow light may be due to the battery being fully charged and not requiring further charging. It could also indicate damage to the electric vehicle's battery or the charger itself. Below is additional information: Specific reasons: When the electric vehicle charger is first plugged in, it shows a red light (indicating charging is in progress), then switches to a yellow light (indicating a false full charge). Continuing to charge for one to two hours will result in a true full charge. If this is the case, there is no need to worry as it is a normal part of the charging process; the electric vehicle is only falsely indicating a full charge. Precautions: Avoid storing the battery in a depleted state. A depleted state refers to when the battery is not charged promptly after use. In this state, sulfation is likely to occur, with lead sulfate crystals adhering to the plates, blocking ion channels, leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a depleted state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan. Regular inspection: Regular checks are essential. If the electric bicycle's range suddenly drops by more than ten kilometers in a short period during use, it is highly likely that at least one battery in the pack has issues such as broken cells, softened plates, or shedding of active material from the plates, causing a short circuit. In such cases, promptly visit a professional battery repair facility for inspection, repair, or replacement.

Why does the AC light turn on automatically when the heater is on?

The reasons why the AC light turns on automatically when the heater is on are as follows: 1. It is caused by turning on the windshield defogger switch. 2. It is due to the design by the manufacturer's engineers. Simply press the AC button to turn it off, which will not affect the use of the car heater. Precautions for using the car heater: 1. Turning on the heater will increase fuel consumption. The car heater and air conditioner operate on completely different principles. When turning on the heater, do not press the A/C button, as it is the compressor start button. Simply adjust the air volume to blow out warm air. 2. Do not turn on the heater immediately after starting the engine. It is recommended to drive for a while until the water temperature gauge reaches the middle position or the blue indicator light goes off before using the heater. It is also advisable to first turn on the external circulation to expel the cold air inside the car, then switch to internal circulation after a few minutes to enjoy the warm air. 3. When fog forms inside the car, you can adjust the heater's airflow direction to blow toward the windshield. The warm air will quickly dry the moisture on the glass, and as the glass temperature rises, the fog will no longer condense. 4. Turn off the heater before shutting down the engine, as prolonged use can damage the engine and shorten its lifespan. 5. During winter, the car interior is often in a sealed state. It is recommended to replace the air filter in advance to prevent respiratory diseases.

Timely window roll-up can avoid property loss and also prevent water from entering the vehicle. Disadvantages of automatic window roll-up after locking the car: First is the installation of the automatic window roller. Some window rollers involve high-risk operations such as wire cutting. The working principle of the automatic window roller is that after locking the car, it automatically supplies power to each window motor to roll up and close the window. Since each time the car is locked means the window motor will be powered, this cycle will definitely cause damage to the vehicle.
