Keep your engine healthy and extend your car’s lifespan with timely oil changes.

How Oil Changes Impact Engine Health

Clean oil is essential for your engine to function efficiently, reducing wear, tear, and overheating. 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.

When Should You Change Your Oil?

Oil change intervals are influenced by factors like your car's make, model, and driving conditions. 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.

Signs Your Car Needs an Oil Change

These are the signs your car is ready for an oil change:

  • Oil That Looks Dark and Gritty: Examine the dipstick: if the oil appears dark and dirty, it’s overdue for a change.
  • Loud Engine Noise: Old oil loses its ability to lubricate effectively, causing the engine to run louder.
  • Dashboard Warning Light: The oil change or check engine light is a clear indicator.
  • Visible Exhaust Smoke: Smoke coming from your exhaust, especially blue or gray, could indicate burning oil.
