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.
