What to Do with the Gear When Waiting at a Red Light in an Automatic Transmission Car?

Does idling a car with the AC on consume more fuel?

Using the air conditioning while the car is idling consumes more fuel in cooling mode, but not in heating mode during winter. Winter heating doesn't consume fuel: When using AC for cooling, the air conditioning system is working, powered by the car's engine. This increases the load and thus fuel consumption. However, using the heater in winter doesn't consume additional fuel. How heating works: The warm air comes from heat generated by the engine operation. After the engine's cooling system dissipates heat from the engine, a fan directs this heat into the cabin to provide warmth. When not using the heater, the fan stops and the vents close, allowing all heat to dissipate into the atmosphere. Therefore, car heating is essentially waste heat recycling and doesn't consume additional fuel. AC button: The AC button controls the air conditioning compressor. You must press it when using cooling in summer. However, heating simply utilizes the car's internal heat circulation and doesn't require activating the AC compressor. To use the heater, you only need to adjust the temperature controls without pressing the AC button.

How Long is the Warranty for Daytime Running Lights?

Generally, the warranty period for lighting components is very short, only 3 months. However, daytime running lights typically use LED light sources, which can last for thousands of hours. The function of daytime running lights: They are lights that make vehicles more easily recognizable during daytime driving. Their purpose is not to help the driver see the road better, but to inform others that a vehicle is approaching. Therefore, these lights are not illumination lights but rather signal lights. While adding daytime running lights can make a car look cooler and more stylish, their primary benefit lies not in aesthetics but in improving vehicle visibility. Studies abroad have shown that using daytime running lights can reduce vehicle accidents by 12.4% and lower the fatality rate in accidents by 26.4%. Light distribution performance of daytime running lights: The most critical aspect of LED daytime running lights is their light distribution performance. They must meet basic brightness requirements without being too bright to avoid disturbing others. Technically, this means the luminous intensity on the reference axis must not be less than 400 cd, and the luminous intensity in other directions should not be less than the product of 400 cd and the percentage corresponding to the point in the light distribution diagram. In any direction, the light intensity emitted by the fixture should not exceed 800 cd.

How often should the transmission fluid in a Magotan be changed?

Volkswagen Magotan's transmission fluid should be changed every 60,000 kilometers. The following are the benefits of regular transmission fluid changes: 1. Ensures smooth and seamless gear shifting, improving driving performance. 2. Provides excellent oxidation resistance, reducing component rust. 3. Contains high-quality extreme pressure additives, offering superior protection for gear sets. 4. Delivers optimal anti-wear effects, extending the lifespan of the automatic transmission. 5. When changing transmission fluid, it is important to use high-quality branded transmission fluid, which effectively protects gears, reduces wear, enhances vehicle performance, saves fuel, extends the fluid's service life, and lowers maintenance and repair costs.

Should You Brake or Accelerate When Changing Lanes?

When changing lanes, you should first accelerate. Things to note when changing lanes: When deciding to change lanes, pay attention to the position of the vehicles behind you. You should be able to see the entire front of the vehicle behind you in the side mirrors before changing lanes. Also, be mindful of blind spots to avoid collisions with vehicles in those areas. When merging, gradually turn the steering wheel. A smooth and linear steering input not only gives the following vehicle enough reaction time but also provides you with ample time to make adjustments. Accelerating when changing lanes: At this point, avoid slowing down gradually. Instead, merge quickly and then tap the accelerator—do not decelerate. The key to changing lanes while driving is to ensure the following vehicle does not need to brake. Change lanes swiftly to minimize the time spent in the transition. Accelerating during the lane change ensures your speed exceeds that of the following vehicle, leaving enough safe distance for both you and the other driver. One more tip: Always keep an eye on the road ahead to avoid rear-ending the vehicle in front. Additionally, avoid changing two lanes at once, as you may only have a limited view of the road ahead and may not be aware of the situation behind you.

What Happens If You Add Salt to Engine Oil?

If it's only for a short period, there won't be major issues, but the oil should be replaced promptly. If used for several days, aluminum components like the bearings will corrode. Effects of Salt on the Engine: Salt is highly corrosive to bearings and piston rings. The damage might not be noticeable in the short term, but prolonged exposure can render the engine useless. Adding sugar or alcohol to the engine is also common. When heated, sugar turns into a sticky paste with no lubricating properties. The consequences may not be immediately obvious, but they lead to reduced engine power, poor performance, and even complete engine failure. Maintenance Tips for Car Engines: Warm-up: During a cold start, engine oil doesn't immediately reach all components. It's essential to warm up the engine to allow the lubrication system to distribute oil properly, ensuring all parts are well-lubricated before driving. This helps minimize wear and tear. Self-check: When starting the engine in a quiet environment, it should produce a deep, rhythmic sound. If the engine noise is sharp or irregular, it may indicate a malfunction, and the vehicle should be taken to a 4S shop for inspection immediately.

Should the Oil Drain Plug Washer Be Replaced?

The washer for the drain plug can be purchased and replaced separately. Theoretically, it should be replaced every time it is removed and reinstalled. Therefore, it is best to purchase and replace it during every oil change to avoid unnecessary trouble caused by oil leaks that would require further handling. The washer needs to be replaced: If it is not replaced, after adding new oil, be sure to run the engine and carefully observe whether there is any oil leakage. If no leakage is found upon inspection, the issue is not significant. If you plan to reuse it, it is recommended not to exceed three uses. The drain plug washer should be replaced—generally, it needs to be replaced once it is damaged. Replacement is necessary if it fails to meet sealing standards: During routine oil changes, the washer is typically not replaced because there is no strict time limit for its replacement. Changing the oil only requires replacing the oil filter. This issue only occurs in a few vehicles. If the washer material is soft, it can provide better sealing when tightened due to its flexibility. However, because it is soft, it may deform after the second use and fail to meet the original sealing standards.
