The car can charge the battery if it only starts but doesn't run, but the charging effect is not good, and it takes a long time to fully charge the battery. The instantaneous power consumption when starting the car is very high, and it takes a long time to replenish the battery's power. It is recommended that if the car is not used for a long time, the negative terminal of the battery can be disconnected to effectively avoid battery discharge. The power source of the generator comes from the engine. After the car starts, the engine begins to work, and the engine transmits power to the generator through the belt, starting to charge the battery. However, the charging efficiency is different between idling and driving states.

Is it cleaner to extract or drain engine oil?

Changing engine oil by draining is the cleaner method. Reasons why draining is cleaner: The drain plug is located at the lowest point of the oil pan, allowing nearly all the engine oil to be drained out. During the draining process, you can visually inspect the condition and color of the old oil to assess the engine's operating status. Additionally, impurities settled at the bottom of the oil pan can be removed, and metal shavings attached to the drain plug can be cleaned promptly to prevent contamination of the new oil. Precautions for changing engine oil: After driving the car into the service bay, let the engine run for a few minutes before shutting it off. This allows the oil in the oil passages to flow back into the oil pan. As the oil flows back, metal shavings in the oil will also settle to the bottom of the oil pan. The drain plug at the very bottom is magnetic and can attract and hold these settled metal shavings.
