An engine has a lot of moving parts, and to keep them working harmoniously, your vehicle relies on oil as a lubricant. Too little or dirty oil can hamper car performance and even lead to overheating from too much friction. To help you stay on top of auto maintenance, watch for the signs below that your oil needs to be changed.

3 Signs That It’s Time to Change Your Oil

1. Poor Fuel Mileage

If your car’s fuel efficiency has dropped recently, the oil may be the culprit. New oil is designed to circulate smoothly throughout the engine components. However, as the oil gathers dirt, it begins to thicken into a sludge. Eventually, this sludge will affect your engine’s performance. Getting a routine oil change is an easy way to keep your car efficient.

2. Excess Exhaust

The gases that get routed to your tailpipe should normally be hard to see, if they’re visible at all. However, if your oil is old or your car has a leak, excess oil may be burning off inside the engine, turning the smoke a dark grey or black. If you notice thick clouds of exhaust, it’s time to visit an auto maintenance technician for an oil change and leak check.

3. Rough Operation

In extreme cases, too little oil can make the engine run rough. This may be especially noticeable when you’re idling. If the car feels like it’s shaking or rattling, get an oil change right away. If the oil runs dry, engine components can generate too much heat, which can lead to expensive or irreparable damage.
