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

How Regular Oil Changes Benefit Your Engine

Oil is crucial for your engine to run smoothly, providing lubrication and controlling the engine’s temperature. Over time, oil breaks down and collects dirt, making it less effective. Failing to change the oil can cause premature wear, overheating, and potential engine damage.

How Often Should You Change Your Oil?

The frequency of oil changes depends on your vehicle’s make, model, and driving habits. As a general guideline:

  • For older vehicles using conventional oil: Every 3,000 to 5,000 miles
  • For modern cars with 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.

Warning Signs It’s Time for an Oil Change

Look for these signs to know when to change your oil.

  • Dark or Dirty Oil: Examine the dipstick: if the oil appears dark and dirty, it’s overdue for a change.
  • Engine Running Loud: Old oil loses its ability to lubricate effectively, causing the engine to run louder.
  • Oil Change Light: A lit dashboard warning light often indicates it’s time for an oil change.
  • Exhaust Smoke: Smoke coming from your exhaust, especially blue or gray, could indicate burning oil.
