The uses of recycling waste engine oil from vehicles are: 1. It can be refined again to produce low-grade lubricating oil; 2. It can be refined into industrial raw materials such as asphalt. Engine oil, which is lubricating oil, serves the following functions: lubrication and wear reduction, cleaning and dispersion, cooling and temperature reduction, sealing and leakage prevention, corrosion and rust prevention, and shock absorption and buffering. The method for changing engine oil is: 1. Start the vehicle's engine to warm it up; 2. Unscrew the oil drain bolt; 3. Remove the oil filter; 4. Apply new engine oil to the gasket of the new oil filter; 5. Pour the new engine oil into the oil pan; 6. Check for leaks in the lower part of the engine and inspect the oil dipstick, then start the engine for testing.

As someone who is very environmentally conscious, I think recycling used motor oil is incredibly important. It significantly reduces the risk of environmental pollution, such as preventing oil from seeping into the soil and contaminating water sources, and avoiding harm to fish, birds, and other wildlife. Used motor oil is not waste; after professional recycling and treatment, it can be turned into re-refined lubricants or industrial fuel, enabling resource circularity and reducing the consumption of new oil. This also helps lower greenhouse gas emissions and supports sustainable development. From my experience in community activities, proper recycling educates people to develop good habits, reducing illegal dumping and protecting our shared home. If left untreated, used motor oil can accumulate toxins over time, even affecting human health, so recycling is a win-win.

I've been changing my own oil for many years and always collect the used oil to take it to a recycling point. This way, the waste oil gets reprocessed into useful products like industrial lubricants or energy raw materials, which is both environmentally friendly and cost-effective. If not recycled and simply dumped, the oil can contaminate the ground, making it difficult to clean up and potentially leading to fines. Recycling avoids these issues and prevents resource wastage. As a car owner, I find this very practical—protecting the environment while reducing pressure on nature. Proper disposal of used oil also prevents leaks or fire hazards, making it much safer. Taking it to a recycling station is usually free and highly convenient, so I recommend making it a habit.

What to Do When a Car Rolls Over?

Solutions for when a car rolls over: 1. Stay calm and avoid making fatal mistakes due to excessive panic; 2. Immediately turn off the engine to prevent hazards such as fire or explosion; 3. Adjust your position, unbuckle the seatbelt, and lower your body. If you cannot open the door, you can choose to break the side window to escape. When striking the side window, aim for the edges of the glass rather than the center; 4. After escaping, do not rush out of the car recklessly. First, observe the surroundings and ensure it is safe before exiting, especially on highways. Make sure to move outside the guardrail and stay as far away from the accident scene as possible to ensure your safety and avoid secondary accidents.

How to Use the Manual Mode in a Tiptronic Transmission?

The method of using the manual mode in a tiptronic transmission is: To switch to manual mode, simply shift the gear lever to the M position. In manual mode, you can shift gears up or down by moving the shift lever accordingly, and the gear changes can be performed while the vehicle is in motion without the need to depress the clutch or brake. A tiptronic transmission combines the manual and automatic shifting modes of a car. The manual mode allows drivers to freely adjust gears and engine speed, providing a thrilling driving experience with a strong sense of sportiness and driving pleasure. Essentially, a tiptronic transmission is still a type of automatic transmission that simulates the operation of a manual transmission through an electronic control system. Its introduction offers drivers greater operational freedom, allowing them to choose the most suitable gear and shifting timing as they see fit.

Can You Shift from D to S Gear While Driving an Automatic Car?

Automatic cars can shift from D to S gear while driving without the need to press the brake or come to a stop. The D gear is the drive gear, where the vehicle prioritizes comfort and fuel efficiency. The S gear is the sport mode, which focuses on high performance. When shifted into S gear, the transmission delays upshifting to allow the engine to deliver greater power. Situations where S gear is not suitable include: 1. High-speed driving is not ideal for S gear, as it is designed to downshift for acceleration, leading to mismatched speed and RPM, increased noise, and higher fuel consumption; 2. Coasting is not recommended in S gear, as it can cause significant wear and tear on the transmission in a short period.
