Idling for 30 minutes can damage the engine. Engine maintenance methods: 1. Use qualified engine oil; 2. Use qualified coolant; 3. Regularly clean the radiator scale; 4. Regularly remove carbon deposits from the engine; 5. Replace the vehicle's air filter, oil filter, and fuel filter on time; 6. Check if the spark plugs are damaged. Solutions for insufficient engine power: 1. Clean carbon deposits from the cylinders, throttle, spark plugs, intake system, and engine; 2. Replace with high-quality gasoline; 3. Clean the air filter; 4. Check the levels of engine oil and coolant.
I believe that idling for 30 minutes in place usually won't immediately damage the engine, but based on experience, doing this long-term can easily lead to some issues. For example, incomplete fuel combustion during idling can cause carbon buildup on the throttle body and spark plugs, affecting ignition efficiency. Having driven both old and new cars, I've noticed that frequent idling for over half an hour significantly increases fuel consumption and makes the exhaust heavier. The solution is to avoid making it a habit, especially not idling for long periods in congested areas; occasionally revving the engine at high speeds on the highway to clear carbon deposits is sufficient. The trick to protecting the engine lies in paying attention to small details, such as regular maintenance checks on engine oil and air filters, which can extend engine life. Cars are designed to be driven, so don't let them idle unnecessarily, wasting fuel and time.
