How Often Should Engine Oil Be Changed for a Car?

1 Answers

Under normal circumstances, the engine oil for a car should be changed every 6 months or 8,000 kilometers. However, the specific interval depends on driving conditions, driving habits, and the type of oil used. It is recommended to change the oil regularly during daily use to reduce engine wear and extend its lifespan. Engine oil is often referred to as the lifeblood of the engine, as the engine cannot function properly without it. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a protective film on the surfaces of various components, preventing direct contact and friction between them.

How to Quickly Charge a Dead Car Battery?

When the car battery is dead and the engine cannot start, you can use the battery jump-start method to charge it. Jump-starting involves connecting another car's battery to the dead battery. Once the power is transferred, the engine can be started, and then the internal alternator will charge the battery while the engine is running. Here are some details about battery charging: 1. If the car battery is dead, it should be charged promptly. At home, you can use a battery charger to charge it. Typically, the battery capacity of a household car is around 60Ah, and the required charging current is one-tenth of the battery capacity, which is 6A. Charging at this current usually takes about 3-5 hours to fully charge. If a lower current is used, it may take around 10 hours to fully charge. 2. When charging the battery at home, it's important to control the charging time. Most people charge overnight, with an average charging time of about 8 hours. If the charging current is too high, the battery may charge quickly, but overcharging can occur, leading to water loss, overheating, and even battery damage. Low-quality batteries may even explode, which is extremely dangerous and requires extra caution.
