Reasons for changing engine oil: Engine oil is as vital to an engine as blood is to a heart. It contains various additives that effectively protect the engine's crucial moving parts, ensuring normal operation. Functions of engine oil: 1. Lubrication: The primary function of engine oil is lubrication. It forms an oil film on the metal surfaces of the engine, reducing wear and tear. 2. Cleaning: It breaks down sludge and deposits generated during engine operation, keeping the engine internals clean. 3. Rust prevention: It neutralizes acidic substances produced during engine use and forms a rust and corrosion-resistant layer, preventing oxidation and rusting of metal components. 4. Sealing: It seals the gaps between pistons and cylinders, ensuring complete fuel combustion and improving fuel efficiency. 5. Cooling: It dissipates high temperatures generated by engine wear, protecting various engine components.

Can I Get My License Directly After Passing Subject 4?

After passing Subject 4, you can receive your license on-site, usually within about 2 hours. Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's license examination. The main content includes: requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and knowledge of post-traffic accident procedures. The Subject 4 test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 points and a passing score of 90. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: in addition to the road test, a safety and common sense test was added, commonly referred to as 'Subject 4,' which assesses 'driving ethics.' Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. Officially, there is no Subject 4. Before the test, students can study traffic regulations through driver's mock test software on mobile devices or computers.

How to Steer When Reversing for Beginners?

Introduction to steering when reversing for beginners: When the steering wheel is turned to the left, the car will rotate with the left rear wheel as the center. At this time, the center point does not move, only the right side moves, causing the rear of the car to turn to the left. When the steering wheel is turned to the right, the car will rotate with the right rear wheel as the center. At this time, the center point does not move, only the left side moves, causing the rear of the car to turn to the right. Below are some related tips for reversing a car: 1. When reversing, master the operation method of "slow driving, fast steering". The reversing speed should be controlled within 5km/h. During reversing, if limited by terrain or the steering angle of the steering wheel, and you need to repeatedly move forward or backward, you should quickly use the vehicle's movement to turn the steering wheel at the moment before stopping after each backward or forward movement, preparing for the next forward or backward movement. Do not forcefully turn the steering wheel after the vehicle has stopped. 2. Do not develop the habit of turning the steering wheel while the car is stationary, as this can more easily damage the vehicle. If you need to move the car back and forth several times, pay attention to turning the wheel in the opposite direction before the car comes to a complete stop at the end of each movement, turning it as much as possible.

What is the actual fuel consumption of the Toyota Corolla 1.6?

The Toyota Corolla 1.6L has 2 models, including the 2017 facelift 1.6L manual GL and the 2017 facelift 1.6L S-CVT GL, both equipped with a 122-horsepower engine, with an NEDC fuel consumption of 6.3L per 100 km. The fuel tank capacity of different Toyota Corolla 1.6L models varies, and the distance that can be covered with a full tank of fuel is as follows: For models equipped with a 122-horsepower engine, the fuel tank capacity is 55L, and the distance that can be covered with a full tank of fuel is 55/6.3*100=873KM. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and ambient temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as rapid acceleration, frequent overtaking, and not easing off the throttle before a red light, will increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn and perform work. Heavier cars will also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low ambient temperature: When the engine block is cold, the injected gasoline is less likely to vaporize during a cold start, requiring more gasoline to burn, which increases fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

The Hatchback-1.6T-Automatic Flagship model, equipped with a 184-horsepower engine, has an NEDC fuel consumption of 8.2L per 100km. The 1.6L-SE-WTCC Edition-AT, SE-AT, Automatic Luxury Edition, and SL Tiandi Edition-AT, equipped with a 121-horsepower engine, have an NEDC fuel consumption of 7.6L per 100km. The remaining 6 models, all equipped with a 121-horsepower engine, have an NEDC fuel consumption of 6.9L per 100km. The fuel tank capacity of different 2013 Cruze models is the same. The distance that can be covered with a full tank of fuel is as follows: Models equipped with a 147-horsepower engine and an NEDC fuel consumption of 7.8L per 100km have a fuel tank capacity of 60L, and can cover a distance of 60/7.8*100=769km with a full tank. Models equipped with a 184-horsepower engine and an NEDC fuel consumption of 8.2L per 100km have a fuel tank capacity of 60L, and can cover a distance of 60/8.2*100=732km with a full tank. Models equipped with a 121-horsepower engine and an NEDC fuel consumption of 7.6L or 6.9L per 100km have a fuel tank capacity of 60L, and can cover distances of 60/7.6*100=789km or 60/6.9*100=870km with a full tank. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline for combustion. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline is less likely to vaporize, requiring more gasoline for combustion, thus increasing fuel consumption. Additionally, in cold temperatures, the engine control unit may increase the idle speed to warm up the engine, which also increases fuel consumption.
