An engine oil and filter change is a routine maintenance task that involves draining the old oil from the vehicle's engine and replacing it with new oil, as well as replacing the old oil filter with a new one. This task is important because it helps to keep the engine lubricated, cool, and clean, and it can improve the vehicle's performance, fuel efficiency, and longevity.
It's important to note that the engine oil and filter should be changed regularly, as per the vehicle's recommended schedule or as indicated by the vehicle's oil life indicator. Neglecting to change the oil and filter can lead to poor engine performance, increased emissions, and reduced engine life.
It's also important to use the correct type of oil and filter for your vehicle as specified in the vehicle's manual or by the oil and filter manufacturer.
