Do you really need to replace your oil filter every time the oil is changed? Well, that depends. This is certainly a much debated topic. But before jumping into this, let's take at the oil itself and see the effect it has on engine function.
The oil filter does exactly as it's name implies, it filters the oil in your vehicle. The engine's oil pump pushes the oil into the filter. Contaminants are caught by the oil filter before it circulates back through the engine. Without filtration, the oil would become saturated with hard, tiny particles that can wear out the oil pump's components and damage the bearing surfaces of an engine.
Three oil change services that cheated customers
When you take your car to a quick lube service to get an oil change, you SHOULD be getting what you pay for. But are you? Well, you may be shocked to find out (I know I was) that there have been some instances where people have been charged for an oil change that they didn't even receive. And even worse, some people were sold additional services that were NOT needed and/or were never performed. The sad thing is that this has probably happened thousands of times all around the world and most people didn't even notice that the services weren't performed.
