Build up sludge reduces the oil's ability to transfer the heat, which increases engine stress. Changing the oil thus makes the car run better and protects the engine.

Does needing an oil change affect acceleration?

A well-lubricated engine is a smooth operator, so when the oil inside becomes old and dirty, it can't lubricate the moving parts as well and as a result, it will not be able to perform as smoothly as normal. This means acceleration can be sluggish and the engine will feel down on power.

Does oil affect gas mileage?

Regular oil changes improve your car's gas mileage. As the fresh oil moves through the engine, the lubrication of the metal parts increases your engine's performance and helps it run more efficiently with less work so it doesn't eat up as much gas.

Is it OK to change oil once a year?
