Mechanic and spark plug

When do I change spark plugs? At Chevrolet Of Turnersville, we get this question a lot from Sicklerville drivers who are interested in learning about this vehicle component. Your owner’s manual will have a precise answer, but it’s usually recommended to change spark plugs every 30,000 miles. Our service center covers how often to change spark plugs and more important spark plug information below!

When Do I Change Spark Plugs: Symptoms

Knowing how often to change spark plugs means knowing when to recognize the symptoms of failing spark plugs. When you start your vehicle, your spark plugs ignite the combustion coil by converting heat from the high voltage current. When your spark plugs aren’t working or you’re asking yourself, “When do I change spark plugs?”, look out for the following symptoms:

  • Engine running rough
  • Engine misfires
  • Engine won’t start or is slow to start
  • Engine idles roughly
  • Struggles to accelerate
  • Bad fuel economy

If you think that you’re in need of new spark plugs, pick up fresh ones at our Turnersville GM parts department. You can also simply schedule service and let our team take care of everything.

Why Change Spark Plugs?

When you consult a Sewell or Williamstown-area parts center to change your spark plugs, you’re investing in improving your vehicle. This is why a recommendation for when to change spark plugs is always included in your vehicle’s maintenance schedule. Here are the benefits you’ll see if you know how often to make the switch:

  • Easy Starts: No one likes it when their vehicle struggles to start. One of the most immediate benefits of knowing how often to change spark plugs is easy vehicle starts!
  • Fuel Economy: As noted above, you get worse fuel economy when you don’t change your spark plugs — as bad as a 30% decrease in fuel economy. Replacing your spark plugs can help to remedy that decline.
  • Combustion System Consistency: Spark plugs are part of your combustion system, which plays an absolutely critical role in your vehicle. Changing them when they are getting worn out keeps your combustion system healthy.
  • Improved Emissions: If you want to have the highest emission standards possible with your vehicle, make sure to change your spark plugs at the recommended time.

Although changing your spark plugs on schedule can help to ensure smooth and easy starts, it’s still a good idea to stock a winter emergency car kit during the colder months.
