What happens after oil change?

After the recommended oil change interval, engine oil will deteriorate and will not be able to fully protect the components from friction which will lead to wear and damage. Just your coolant system alone is not enough to cool the engine.

Does engine run smoother after oil change?

Oil changes enhance, mileage and improve fuel economy. Unchanged oil loses the viscosity required to maintain its functions and thus affects the performance of the vehicle. You will notice that the car does run better after an oil change.

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.

What happens if you skip oil change?

If you happen to miss an oil change and the motor oil starts to lose effectiveness, these parts won't be properly lubricated. This could result in pieces grinding together or simply not moving at the rate your car needs to perform. Additionally, motor oil works to regulate engine temperature.

Why did my mpg drop after oil change?

If you were using one type of oil and then replaced with a different oil that does not meed specifications of the motor by being too thick then it would affect fuel mileage by maybe 1 mpg. If you are loosing more than this then look elsewhere. Check tire pressures and filters.
