Regular oil changes are one of the best ways to ensure your vehicle has a long life. Engine oil helps lubricate moving parts and dissipates heat to prevent wear and tear. Though it’s important to stick to your car’s recommended schedule—usually set by mileage and found in your owner’s manual—there are more immediate indications that call for attention. To protect your engine, below are some of the key signs it's time to change your oil.

How to Know Your Car Needs an Oil Change

1. Rattling or Knocking Noises

Engine oil smooths out the function of moving parts in the engine. When the oil levels are too low or the oil is not thick and viscous enough, you might hear knocking or rattling sounds from under the hood. When this occurs, stop the vehicle as soon as possible, check the oil level, and add more as necessary. Then schedule an oil change to remove any metal shards that might have accumulated due to engine friction.

2. Persistent Low Oil Levels

You should make a habit of checking your engine oil levels at every refueling stop. If you notice the levels are consistently low, it could mean the car is burning oil or leaking oil from the pan or seals. Schedule an appointment with a reputable service station and ask them to examine the car for additional oil system problems. For instance, if it’s burning oil, it may be leaking past the valve seals into the combustion chamber.

3. Time or Mileage

Oil breaks down over time, and it can collect debris and moisture as it runs through the engine. Most manufacturers recommend an oil change every 5,000 to 7,500 miles or, at a minimum, once every six months. Your manual will specify the recommendation for your make and model. Vehicles that are older and have 100,000 miles or more on the engine require more frequent service. In that case, plan on changing the oil every three months or 3,000 miles.
