How to Check if the Battery Has Power?

Methods to check if the battery has power: 1. Check the battery's charge indicator. A green indicator means the battery is fully charged, a black indicator indicates insufficient charge, and a colorless or light yellow indicator means the battery is nearly depleted. 2. Measure the battery's static voltage. If the voltage is below 11.5V, it indicates the battery is low on power. If the voltage is below 10.9V, it means the battery is almost completely discharged. When installing a battery in a vehicle, always connect the positive terminal first, followed by the ground terminal. When removing the battery from the vehicle, reverse the steps to prevent potential damage to the battery in case the wrench accidentally grounds.

Should the Oil Filter Be Replaced During an Oil Change?

When changing the engine oil, it is necessary to replace the oil filter as well. The oil filter is designed to remove impurities, metal particles, sludge, and other contaminants from the oil, ensuring that the filtered oil remains clean. This helps extend the lifespan of both the oil and the engine. If the oil filter is not replaced during an oil change, the new oil will become contaminated as it passes through the old filter, which still contains trapped dirt and debris. Over time, a neglected oil filter will lose its filtering efficiency, becoming virtually ineffective. Prolonged use of a dirty filter can accelerate wear and tear on internal engine components and, in severe cases, lead to oil burning issues.
