How Often to Change Your Spark Plugs


Keeping up with routine maintenance like oil changes and tire rotations is typically on most Port Huron-area driver’s radar. But do you know how often to change the spark plugs in your vehicle? Most experts recommend spark plug replacement every 30,000 miles, but the exact frequency ultimately depends on your specific make and model. Your owner’s manual will provide you with more guidance, or you can connect with the Moran Chevrolet Fort Gratiot service team to schedule an inspection and get recommendations on when your next spark plug replacement is due.

When Do I Change Spark Plugs?

Are you asking yourself, “When do I change spark plugs?” It’s important to know how they function, first and foremost. Spark plugs are a component of your ignition, and they work to move a high-voltage current from the ignition coil to ignite the combustion chamber when you turn the engine on. When spark plugs aren’t working as they should, you might notice the following:

  • Difficult start, or no start at all
  • Misfiring engine
  • Rough running engine
  • Vibrations when idling
  • Slow acceleration
  • Excessive fuel consumption

Benefits of Changing Your Spark Plugs

Incorporating spark plug replacement in your maintenance schedule will yield the following benefits:

  • Enhanced Fuel Economy: Worn-out or malfunctioning spark plugs have the potential to reduce your fuel economy by as much as 30%. Brand-new spark plugs will improve your mpg ratings on the Marysville-area roads.
  • Overall Ignition Health: When your spark plugs function properly, they promote the continuous production of combustion, which ensures a healthy ignition system.
  • Effortless Vehicle Starts: New spark plugs guarantee that every time you turn your key in the ignition or push the start button, your vehicle will come to life without issue.
  • Less Harmful Emissions: Eco-conscious drivers in the Lake Port area will be pleased to know that replacing your spark plugs will improve your emissions.
