What are the consequences of overdue maintenance?

Failure to perform proper maintenance will increase the failure rate, potentially leading to breakdowns on the road or electrical circuit malfunctions. Not changing the engine oil places greater burden on the engine. Vehicle maintenance is crucial as it extends service life and reduces failure rates. Additional reference materials are as follows: 1. Engine oil maintenance cycle: Engine oil has a shelf life. Generally, vehicles require maintenance every 6 months or 5,000 kilometers, while some models may need maintenance once a year or every 10,000 kilometers. 2. Spark plug maintenance cycle: For most vehicles, spark plugs typically require maintenance every 60,000 kilometers. Specific maintenance intervals vary by vehicle model, so refer to the maintenance manual. Spark plugs are used for ignition and thus operate at high temperatures.
