Changing the engine oil takes about one hour. It is essential to replace the engine oil regularly. Only by changing it on time can you prevent increased engine wear due to reduced lubrication performance of the oil. However, when the mileage exceeds the recommended interval by only a small amount, the impact of the oil on the engine remains relatively minor. Engine oil is used for lubricating internal combustion engines. Its primary functions include reducing friction and wear on moving parts, removing sludge (one of the functions of dispersants) and varnish (detergents) from the engine, neutralizing acids produced by fuel combustion and oil oxidation (detergents), improving piston ring sealing, and cooling the engine by carrying heat away from moving components.

What does the highway ETC system refer to?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. On highways, there will be one or more ETC lanes. ETC charging method: Through dedicated short-range microwave communication between the vehicle-mounted RFID tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, the system connects with the bank for background settlement processing via network technology, thereby achieving the purpose of vehicles passing through bridge and road toll stations without stopping to pay tolls. Banks install this type of ETC express card with a 'pass first, charge later' approach. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. The photocopy of the driver's license must include the page with the most recent annual inspection seal; Postal credit card application form. This credit card is used to bind the ETC card. After obtaining the credit card, swipe it twice and present the POS receipt to the designated postal outlet to receive and install the ETC onboard device for free, with no charges during the process; Be between 18 and 60 years old; Own a vehicle under your personal name. Below are precautions for ETC installation: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward angle of the windshield, which reduces the driver's field of vision. If ETC installation does not consider this, it will increase the driver's blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Do not remove it randomly once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If removed randomly, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle ahead. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to charging failure. When using a debit card bound to ETC, insufficient balance will also cause charging failure.

What is the NEDC combined fuel consumption of BMW?

NEDC combined fuel consumption serves as the reference standard for electric vehicle range testing in China. The NEDC test cycle consists of two parts: ECE (Urban Driving Cycle) and EUDC (Extra Urban Driving Cycle). Purpose of ECE: Used to simulate traditional urban road conditions, composed of 4 ECE15 cycles. Each ECE15 cycle includes 15 driving conditions such as acceleration, deceleration, constant speed, and idling. The ECE duration is 780 seconds, with a total driving distance of 4.052 km, an average speed of 18.7 km/h, featuring characteristics of low speed, low load, and low exhaust temperature. Purpose of EUDC: EUDC is used to simulate suburban road conditions, with a duration of 400 seconds, a driving distance of 6.955 km, an average speed of 62.6 km/h, and a maximum speed of 120 km/h in this segment.

How to Call for Help When a Tire Blows Out on the Highway?

Tire blowout on the highway requires first firmly holding the steering wheel for self-rescue. Below are the methods for self-rescue during a tire blowout on the highway: 1. Method: Stay calm, use engine braking to allow the car to coast slowly, also known as manual gear shifting. Do not suddenly release the accelerator pedal; instead, gradually ease off the throttle because the deceleration from a blowout is very strong. Avoid stepping on the brake pedal, as it can further destabilize the car, leading to a spin or rollover. Hold the steering wheel firmly to maintain control of the direction and avoid sharp turns. You can use intermittent braking, rhythmically pressing and releasing the brake. 2. Precautions: Whether the tire blowout occurs on the highway or an ordinary road, whether calling for help or changing to a spare tire yourself, the first thing to do when encountering a blowout is to hold the steering wheel firmly. Continuously applying the brakes can lead to the danger of a rollover. Then, remember to turn on the hazard lights and place a warning triangle behind the car.

What materials can be used to repair a broken taillight cover?

A broken taillight cover can be repaired using glue and plastic. Here are some maintenance precautions for car headlights: 1. Replacement: Car headlights must maintain good sealing, especially to prevent contamination and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the mirror surface with fingers to prevent leaving sweat or oil marks that could cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular inspection: Regularly check and adjust the headlight beams to ensure the headlight's illumination distance meets requirements and that the high and low beams are aligned. The diffuser glass should be correctly installed as specified to prevent loosening or displacement and to maintain the vertical alignment of the prisms.

What is the maximum speed allowed on a highway with a speed limit of 120?

Highway speed limit 120 maximum speed is 120 mph. Although China's traffic regulations stipulate that speeding within 10% of the speed limit will not result in penalty points or fines, some regions may still treat it as a traffic violation, requiring the driver to handle it at the traffic violation processing window. Therefore, safety comes first, and speeding should be avoided. Below are specific details about speeding penalties: 1. Less than 10%: If the speed exceeds the limit by less than 10%, a warning will be issued. 2. Between 10% and 20%: If the speed exceeds the limit by more than 10% but less than 20%, a fine will be imposed, and 3 penalty points will be recorded. 3. Between 20% and 30%: If the speed exceeds the limit by more than 20% but less than 30%, a fine will be imposed, and 6 penalty points will be recorded. 4. Between 50% and 70%: If the speed exceeds the limit by more than 50% but less than 70%, a fine will be imposed, 12 penalty points will be recorded, and the driver's license may also be revoked.
