For older vehicles that have run over 150,000 kilometers, major repairs are a possibility. A major car repair mainly refers to an engine overhaul, which involves extensive disassembly of the engine for maintenance. The engine determines a significant portion of the car's performance, and its precision requirements are quite stringent. If the repair process disrupts the engine's precision alignment, a series of issues can naturally arise. Here is additional information: Severe oil burning due to wear and tear will definitely affect normal driving and lead to a vicious cycle of worsening engine carbon buildup. Oil burning is primarily caused by aging valve stem seals and engine wear, such as piston ring wear, cylinder liner wear, and piston wear, which result in poor sealing. In such cases, a major repair is necessary.

After last year's major overhaul, my car really feels like a brand-new one—the acceleration is noticeably stronger, and fuel consumption has returned to normal levels. It's an absolute joy to drive. However, I must remind you that a major overhaul isn't a cure-all—especially if the engine disassembly and reassembly aren't done properly. During the break-in period for new parts, you might encounter various minor issues like slight abnormal noises or oil seepage, which are quite common. I once had the oil warning light come on just a month later, which gave me a scare, and I had to rush back to the shop for a redo. The quality of the repair shop's work is crucial—don't cut corners by choosing a small workshop to save money, or you'll be dealing with endless headaches later. Also, a major overhaul costs tens of thousands, and it definitely depreciates the car's resale value. Buyers tend to haggle aggressively once they hear the engine has been worked on. After driving it for over half a year now, I've learned my lesson—I regularly check the oil lines and wiring to prevent secondary failures. Overall, the pros outweigh the cons. As long as you ensure the repair quality, the car can easily run for several more years without issues.

After years of serving as a family car, my old vehicle underwent significant changes following a major overhaul. The engine noise quieted down, and my kids in the back seat said it felt much more comfortable. However, there are negative aspects to be mindful of, such as reduced reliability—before long highway trips, I always feel uneasy and check the oil level and belt condition, fearing a breakdown midway. The new parts replaced during the repair require a break-in period; avoid stomping on the accelerator within the first 500 kilometers, or else the parts will wear out faster, necessitating shorter maintenance intervals. The cost wasn’t cheap, but if you want to save money, you have to accept some risks. I recommend testing the car’s condition more on urban roads after a major repair and addressing any issues early by returning to the 4S shop for checks. My car has been running stably for over a year since the repair, but psychologically, there’s still a bit of lingering concern. I’ve become more meticulous with regular maintenance—safety first, after all.

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.
