How Often to Change Your Spark Plugs

North Dakota drivers ask the experts at our Minot, Bismarck, and Williston service centers alike many questions about car maintenance and repairs, including, “How often to change spark plugs is considered normal?” The answer? Roughly every 30,000 miles. At least, that’s the average mileage at or around which most drivers find themselves buying new spark plugs. Read on or contact us to learn more car maintenance tips.

When Do You Change Spark Plugs? 

Spark plugs are key to the combustion process in gasoline engines. By contrast, diesel engines run hot enough that the fuel self-ignites. Gasoline engines, however, require spark plugs to provide the electrical spark required to ignite the gasoline in the cylinder, providing the energy required to ignite and thus, provide propulsive energy to the vehicle.

Park plugs also provide the high voltage current required to start a vehicle. Accordingly, spark plugs must be changed out frequently to promote optimal engine efficiency and provide the power needed to start the car. Here are some signs your spark plugs need replacing:

• Engine runs rough
• Slow or no start
• Engine misfires
• Rough idling
• Poor acceleration
• Poor fuel consumption

Benefits of Changing Your Spark Plugs

As you might expect, the opposite of the above symptoms of bad or aging spark plugs can occur when you actually change out your spark plugs for a fresh set. Here are some highlights that are especially appreciated when Minot drivers change their spark plugs:

• Your Vehicle Starts Smoothly – Replace your spark plugs and you’ll likely feel your vehicle starting much more smoothly.
• Improved fuel economy – Having worn-out spark plugs can decrease your fuel economy by as much as 30%, so replacing spark plugs can restore efficiency by that amount.
• Consistent combustion system – Spark plugs allow for continuous combustion, leaving your vehicle’s engine running as efficiently as possible.
• Less harmful emissions – Replacing your vehicle’s spark plugs can not only help increase your gas mileage but also improve your vehicle’s overall emission output.
