What to Do If a Car Is Not Driven for a Long Time?

If a car is not driven for a long time, the following measures should be taken: 1. Prevent the oxidation of the 'four fluids': engine oil, brake fluid, coolant, and windshield washer fluid. 2. Battery charge: If the car is left unused for more than two months, disconnect the negative terminal of the battery; only the negative terminal needs to be disconnected, and the positive terminal should remain untouched. 3. Chassis protection: Park the car on a flat surface to ensure proper tire pressure and prevent localized deformation of the tires during prolonged parking. 4. Rust prevention for the body: Address any damaged paint on the car body, even minor damage, to prevent rust from spreading.
As a technician with over a decade of car repair experience, I've seen many vehicles develop issues after long-term parking. Let me tell you, you must disconnect the battery before parking, otherwise it'll be completely drained in less than 3 months. Park in a dry, shady spot - avoid parking under trees as bird droppings and tree sap can damage the paint. Inflate the tires to full pressure, preferably 0.5 psi higher than normal, otherwise deformation becomes a major safety issue when driving. Always choose a breathable car cover - one client used plastic sheeting and the paint grew mold underneath. Don't leave the tank half empty either; fill it up to prevent rust in the fuel tank. When driving after long storage, remember to go slow - the brakes might feel spongy at first and require several pumps to return to normal.
My car was parked in the underground garage for half a year, now let me share some practical experience. Disconnecting the negative terminal of the battery is the most effective - it started right up after reconnecting when work resumed. Placing cardboard under all four tires is a must-do, as prolonged pressure can deform the rubber. Before sealing the doors and windows, toss two packs of desiccant inside the car, otherwise the mildew smell can be overwhelming. If possible, remotely start the engine for 10 minutes weekly - a friend who borrowed my garage did this, and the engine ran exceptionally smooth when work resumed. Pay special attention to the brake discs; ease into the first hard brake after resuming use - I almost hit a wall last time. Change the engine oil immediately after resuming use, as it degrades during prolonged parking.
