Regular oil changes are key to ensuring your engine runs smoothly and lasts longer.

How Regular Oil Changes Benefit Your Engine

Your car’s engine relies on clean oil to lubricate its moving parts, reduce friction, and regulate temperature. Over time, oil breaks down and collects dirt, making it less effective. Without regular oil changes, this can lead to increased wear and tear, overheating, and even engine failure.

Recommended Frequency for Oil Changes

Oil change intervals are influenced by factors like your car's make, model, and driving conditions. Here are some general recommendations:

  • For conventional oil in older vehicles: Oil changes should happen every 3,000 to 5,000 miles
  • For newer vehicles using synthetic oil: Every 7,500 to 10,000 miles

Check your owner’s manual or consult a mechanic to figure out the ideal schedule for your car.

Signs Your Car Needs an Oil Change

Pay attention to these warning signs that indicate it’s time for an oil change:

  • Dirty Oil: If the oil on the dipstick is thick and dark, it’s time to replace it.
  • Loud Engine Noise: Old oil can't lubricate the engine as effectively, leading to increased engine noise.
  • Check Engine Light: The oil change or check engine light is a clear indicator.
  • Visible Exhaust Smoke: If you see blue or gray smoke, your oil may be burning, signaling a problem.
