Yes, it can be harmful. If a car remains parked and unused for an extended period, the engine oil may oxidize and thin out, losing its lubricating effectiveness. Additionally, gasoline can evaporate due to insufficient sealing, preventing it from meeting the standard for normal combustion. Extended information: Forced starting: If the car is forcibly started, the lack of lubrication from the oil and the increased combustion temperature of the valves can directly cause the fuel pump to clog and the engine's intake and exhaust valves to break. Precautions: The car's engine should be started and driven at least once a month, allowing it to idle until the oil pressure light turns off. The vehicle should also be driven a certain distance to help re-coat the internal transmission components and rear drive shaft with oil and to wear in the clutch plates.

Leaving a car parked for three months? I have some experience with this, and battery issues are the most common problem. When a vehicle sits idle for too long, the battery will self-discharge, potentially leaving you with a dead battery when you try to start it, which could mean calling for a tow truck. Tires are another concern; if parked in the same spot for an extended period, the sections under pressure can deform, leading to unstable driving and even safety risks. Additionally, brake pads might stick, causing unusual noises when you first drive. It's advisable to take the car for a short drive around the block or let the engine run for about ten minutes weekly to recharge the battery and keep the moving parts active. During significant weather changes, park in a garage or use a car cover to protect against dust and moisture. Don't overlook the small things—preventative maintenance can save you from bigger headaches.

Parking for three months really requires attention to fuel and fluid aging. I often help friends deal with this issue. Ethanol gasoline tends to absorb moisture and deteriorate, which can corrode the inside of the fuel tank and fuel injectors over time. Engine oil also precipitates impurities, leading to insufficient lubrication and rapid engine wear. It's best to fill up the tank and add fuel stabilizer before parking to protect the system. Fluid checks are also essential, such as coolant and brake fluid, as aging can reduce their effectiveness. Regular driving or using professional maintenance tools can prevent the car from acting up when you return.

The car has been parked for three months? Minor electronic system issues may arise. A depleted battery is the main concern, and sensors like cameras or radars could get covered in dust, leading to false alerts. It's advisable to disconnect the battery's negative terminal or use a maintenance charger to keep it powered. Performing a remote start once a week or simple maintenance can ensure everything operates smoothly.
