Is It Harmful to Leave a Car Parked for a Long Time with a Full Tank of Gas?

[MacJoel]

Leaving a car parked for a long time with a full tank of gas can cause damage to the vehicle. Gasoline that is stored for too long can oxidize severely, forming gum deposits. These deposits can cause the valves to stick and prevent them from closing properly. At high temperatures, the deposits decompose into carbon deposits that accumulate on the cylinder walls, piston tops, and cylinder heads, leading to poor engine performance, knocking, and increased wear. More details about long-term car storage are as follows: 1. Detail One: During long-term parking, in addition to regular maintenance of the battery, other car components also require periodic cleaning or replacement, such as vehicle fluids. Engine oil, coolant, brake fluid, and power steering fluid all have expiration dates, and they may need replacement even if the car is not driven. 2. Detail Two: Taking engine oil as an example, once opened and poured into the engine, the oil comes into contact with air and typically has a shelf life of about one year.
