Proper engine oil helps dissipate heat generated by the engine.

Over time, as the oil breaks down and loses its ability to dissipate heat effectively, the engine may start to overheat.

If you notice your engine temperature gauge rising above normal or see warning lights indicating engine overheating, it could be a sign that your oil change is overdue.

5. Oil color and consistency

When oil is fresh, it appears amber or light brown and has a smooth consistency.

Over time, the oil can become darker, thicker, and more sludgy due to the accumulation of contaminants and depletion of its additives.

Checking the oil on your dipstick and noticing excessively dark or dirty oil can indicate the need for an oil change.

6. Increased exhaust emissions

Old and dirty oil can contribute to increased levels of harmful emissions from your vehicle’s exhaust.

If you notice excessive smoke or an unpleasant odor coming from the exhaust, it could be a result of overdue oil changes affecting the engine’s combustion efficiency.
