Excessive vehicle weight, severe engine carbon buildup, and low tire pressure may all be reasons for a sudden increase in Audi's fuel consumption. Excessive vehicle weight: Vehicle weight has a significant impact on fuel consumption. When fully loaded with cargo, the car's fuel consumption will inevitably increase. Therefore, try to minimize unnecessary items in the car to reduce weight and save fuel. Severe engine carbon buildup: If there is a significant amount of engine carbon buildup in a short period, it can also lead to higher car fuel consumption, possibly due to the use of substandard fuel. Low tire pressure: If the tire pressure is insufficient, rolling resistance will greatly increase. According to tests, if the tire pressure is 2psi lower than the specified value, fuel consumption will increase by 1%. Additionally, tire misalignment or excessive wear may also increase fuel consumption.

Will the Engine Get Flooded When Driving in Heavy Rain?

Driving in heavy rain will not flood the engine. This is because the engine's air intake passes through the air filter, which is located in the engine compartment and is protected by the hood, preventing water from entering. Unless the hood is left open or the air filter is removed during rainy conditions, water cannot enter. If water does enter the engine, it can easily cause the engine to stall. If the engine does not stop running, water may enter the spark plugs, leading to engine failure. Below are specific details about car maintenance: 1. Mileage for the first car maintenance: New cars should undergo their first maintenance at 3 months or 3,000 kilometers. During the initial break-in period, many parts of the car need to be properly worn in. Therefore, the engine oil and oil filter should be replaced at 3,000 kilometers, the engine oil, oil filter, and air filter at 7,500 kilometers, and then maintenance should be performed every 5,000 kilometers. It is also important to choose an authorized 4S shop for maintenance. 2. Different engines require different maintenance intervals: Cars have naturally aspirated engines and turbocharged engines. For vehicles with turbocharged engines, maintenance is required every 5,000 to 7,000 kilometers, while for naturally aspirated engines, maintenance intervals range from several thousand to 10,000 kilometers.

What is the difference between turning on AC and not turning on AC in a car?

Only by turning on the AC switch on the car's air conditioning control panel will the car's air conditioning start to cool. If this AC switch is not turned on, the car's air conditioning will not cool, and it will blow out natural air. The following is a related introduction to car air conditioning: 1. Introduction to car air conditioning: The car air conditioning device (air-conditioning-device), referred to as car air conditioning. It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it creates good working conditions for the driver and plays an important role in ensuring safe driving. 2. Car air conditioning devices: Generally include refrigeration devices, heating devices, and ventilation devices. This combined device makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.

What is the minimum following distance on highways?

When driving on highways, if the speed exceeds 100 kilometers per hour, the vehicle should maintain a distance of at least 100 meters from the vehicle in front in the same lane. If the speed is below 100 kilometers per hour, the distance can be appropriately reduced, but the minimum distance should not be less than 50 meters. Precautions for driving on highways: 1. Do not exceed the speed limit: Maintaining a safe speed is the most important guarantee for safe travel on highways. Speeding and other major traffic violations are significant causes of traffic accidents. 2. Avoid changing lanes arbitrarily: Randomly changing lanes on highways can disrupt traffic order and cause danger if the following vehicles cannot avoid in time. 3. Do not tailgate large vehicles: If you follow large vehicles on highways, your view will be blocked, making it impossible to observe the road conditions ahead. If you must follow, slow down and increase the safe distance, then find an opportunity to overtake when it is safe.

Is the gas price at highway service area stations the same as outside?

Highway service area gas stations operated by the same company in the same region have the same fuel prices as those outside. This is because gas station prices across the country are uniformly set by the National Development and Reform Commission. Below is relevant information about gas stations: 1. Gas station overview: A gas station is a refueling facility that provides retail gasoline and motor oil services for cars and other motor vehicles, typically supplying fuel oil, lubricants, etc. 2. Precautions at gas stations: Since petroleum products sold at gas stations are highly flammable, volatile, prone to leakage, and can accumulate static electricity, gas stations prioritize "safety" as their foremost principle. Open flames are strictly prohibited at gas stations, as are any operations that may generate sparks. It is forbidden to add gasoline to a car's carburetor or oil drum. All vehicles must turn off their engines before refueling, and all hazardous materials are strictly prohibited from entering the station.
