Can You Change the Oil Without Replacing the Filter?

[EvanMarie]

You cannot change the oil without replacing the filter. The filter's role is to remove impurities from the engine oil. Over time, these impurities can cause blockages. Additionally, a certain amount of oil remains inside the filter. If you only change the oil without replacing the filter, the new oil will mix with the old oil, reducing the oil's lifespan. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication, reducing friction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and acting as a shock absorber. It is often referred to as the 'blood' of a car. The oil filter, or oil purifier, filters out debris, sludge, and moisture from the oil, ensuring clean oil is delivered to all lubrication points.
