Why do I need an oil change?

If you change your oil regularly your car will have proper lubrication that reduces the amount of heat produced by the engine. Oil changes also get rid of dirt and debris, which makes your engine run slower. If your engine heats up because of old oil, it will wear down and eventually stop working properly.

What are some symptoms for an overdue oil change?

Low Oil Level, Dark/Dirty Oil, Burning Oil Smell, Weak Fuel Economy, Stalling Engine, Overheating Engine, Service Warning Lights, Dark Exhaust Smoke
