How Often to Change Spark Plugs

Changing Spark Plugs

Auto maintenance experts like the service technicians here at Biggers Chevrolet know a thing or two about cars because they’ve been repairing them for a while. If they provide automotive service or maintenance advice, it’s pretty likely to be evidence-based and solutions-oriented. Still, vehicles are complex machines. While it’s recommended that you change your spark plugs about every 30,000 miles for optimal Streamwood driving, that estimate can vary. Consult your vehicle’s owner’s manual for additional information, or contact us if you need help with your spark plugs.


When Do I Change Spark Plugs in My Car? 

Your vehicle’s spark plugs play a huge role in its proper daily operation by providing the electric current needed to ignite the combustion chamber every time you start your engine. When your spark plugs don’t work correctly, they require replacement. Not only should you consider replacing your spark plugs every 30,000 miles, but you should also consider doing so when you experience:

  • Rough idling
  • Slow or no start
  • Engine misfiring
  • Poor quality acceleration
  • Rough running engine
  • Abnormally high fuel consumption

Why Change Your Spark Plugs Frequently?

There are plenty of additional reasons to change your spark plugs frequently aside from those we’ve just listed above. Find out the benefits of changing out your spark plugs as part of the preventative maintenance schedule for your new Chevrolet vehicle:

  • Increased Fuel Efficiency – Worn out spark plugs can decrease fuel efficiency by up to 30%, but replacing them can help gain that difference back.
  • Consistent Combustion System – New spark plugs that function properly allow for continuous, uninterrupted combustion to occur, leaving your vehicle’s system running normally.
  • Your Vehicle Starts Smoothly – Replacing worn spark plugs can help ensure that every time you start your car, it works optimally.
  • Less Harmful Emissions – Replacing your vehicle’s spark plugs can not only help increase your gas mileage but also improve your overall vehicle emissions.
