What is an Oil Drain Plug?
2 Answers
An oil drain plug is essentially the drain screw located at the bottom of the oil pan. If it is not replaced regularly over time, the threads may wear out, necessitating the replacement of the entire oil pan. Replacement Interval for Oil Drain Plug: The oil drain plug of a motor vehicle's engine should be replaced along with the engine oil, typically every 6,000 kilometers or six months. After removal, the plug will be coated with oil that cannot be completely cleaned off. Reusing it may lead to oil leaks. Where to Replace the Oil Drain Plug: During routine maintenance, motor vehicles require the replacement of engine oil, oil filter, and the oil drain plug. You can choose to have this service performed at the brand's authorized service center or a reputable local repair shop. When replacing the engine oil, it is crucial to select a genuine brand and the correct specification for your vehicle model. After replacement, make sure to note the maintenance mileage for future reference.
Last time I got my car serviced, I asked the technician this exact question. The oil drain filter is actually the oil filter, specifically designed to trap metal debris and carbon deposits from the engine oil. As a seasoned driver with ten years of experience, I know that changing the oil filter is mandatory during an oil change—it's like putting a mask on the engine. If you skip replacing it for too long, the filter paper gets clogged, disrupting oil circulation. At best, your fuel consumption will spike; at worst, you risk cylinder scoring and a major overhaul. I follow the manual and replace it every 5,000 km. When you open up the old filter, you can clearly see the blackened impurities inside, with metal shavings stuck to the magnetic ring.
