What are some car repair experiences?

Car repair experiences are as follows: Corrosive wear: After fuel is burned in the engine combustion chamber, many harmful substances are produced. Generally, 1-5 pounds of nitrogen and sulfuric acid are generated for every 100 gallons of gasoline burned. These substances not only corrode the cylinders but also enter the engine through the three piston rings (top, middle, and bottom rings), causing metal corrosion to major engine components such as the camshaft and crankshaft. This type of corrosion cannot be eliminated by using lubricating oil alone. Rust wear: After the engine is shut down, it cools from high temperature to low temperature. This temperature change process causes water condensation and even accumulation inside the engine. This results in severe metal rusting in the engine, especially when the engine is restarted for short-distance operation before the temperature has a chance to evaporate the moisture. In such cases, the situation becomes even worse. This is also something that lubricating oil cannot prevent. Severe wear caused by dust: The engine needs to intake air during combustion, and even the best air filtration devices cannot completely prevent dust from being inhaled into the engine along with the air. The severe wear caused by inhaled dust cannot be fully eliminated by lubricating oil. This type of wear is particularly prominent in arid, low-rainfall, and sandy areas.
I've been fixing my own car for several years now, mainly through self-learning and online tutorials, which has saved me a lot of money. It all started with changing the oil, where I initially didn't tighten the filter properly, causing a leak and dirtying the garage floor. Over time, I learned to change tires and handle battery issues, like testing the voltage to determine if a replacement was needed when the battery aged. Cleaning the air filter is also straightforward—just replace it every quarter. I even tried changing brake pads once; although it was nerve-wracking, I succeeded in avoiding expensive repair bills. Safety always comes first, so I wear gloves and ensure the car is securely supported with a jack. The experience has taught me that regular maintenance can prevent major issues, such as checking tire pressure to avoid blowouts. These small tasks have built up my confidence over time, and now I can even help neighbors with common car troubles.
