Regular oil changes are crucial for keeping your car running smoothly and efficiently. Oil lubricates the engine, reducing friction and wear on the moving parts. Over time, oil breaks down and becomes less effective at lubricating, which can lead to engine damage and poor performance. It is recommended to change your oil every 5,000 to 7,500 miles or every six months, whichever comes first. Some newer cars have smart sensors that can alert you when it's time for an oil change, but it's still important to follow the manufacturer's recommendations. If you neglect regular oil changes, you may experience loss of engine power, decreased fuel efficiency, and even engine failure. Additionally, dirty oil can build up sludge in the engine, causing further damage. By staying on top of your oil changes, you can extend the life of your car and avoid costly repairs down the road. So, make sure to schedule regular oil changes to keep your car running smoothly and efficiently.
