Car Maintenance: Based on Mileage or Time?

[NicoleLynn]

Whether car maintenance should be based on mileage or time depends on different situations. For frequently used cars, maintenance is determined by mileage; otherwise, it is based on driving time. Below are the specific impacts of not maintaining your car on time: 1. Bearing labor costs: For cars under warranty, if basic maintenance is not performed on time, once a malfunction occurs, you will need to pay for parts and labor fees at the 4S shop. If the issue is due to circuit problems, the manufacturer will not be responsible. 2. Compromising driving safety: As engine oil comes into contact with air and is exposed to heat, it can gradually oxidize. With the increase of acidic substances, sludge, and iron particles in the oil, the oil color will darken, and its viscosity will decrease. Not changing the oil for a long time may lead to these deposits blocking oil passages, causing dry friction in the engine and severely affecting its lifespan. 3. Smoke and fire: The cooling efficiency of the coolant decreases, making it prone to forming scale. Continuing to drive with an overheated engine can easily lead to smoke and fire.
