Why Spark Plugs Wear Out Faster Than You Think
Your engine needs three things to run: air, fuel, and spark. Spark plugs provide that spark every time you start your vehicle. Even though they are small, they have a big job.
Over time, spark plugs wear out. When they do, your engine may not run as well as it should.
What Do Spark Plugs Do?
Every time you start your vehicle, the spark plugs ignite the fuel inside the engine. That small spark creates the power needed to get you down the road.
Each spark plug fires thousands of times during every drive. After years of use, they begin to wear out.
Signs Your Spark Plugs May Be Worn
Spark plugs usually do not fail all at once. Most of the time, they wear out little by little.
Some common signs include:
- Hard starting
- Rough idle
- Slow acceleration
- Lower fuel mileage
- Engine misfires
- The Check Engine Light comes on
If you notice any of these signs, it may be time to have your vehicle checked.
Waiting Can Cost More
Many people keep driving because the vehicle still runs. The problem is that worn spark plugs can make the engine work harder than it should.
A small problem today can lead to bigger repairs later. Replacing spark plugs on time can help protect other parts of your engine.
Every Vehicle Is Different
Some spark plugs last about 30,000 miles, while others can last 100,000 miles or more. The best time to replace them depends on your vehicle and the type of spark plugs it uses. Your owner's manual gives a good starting point, but a professional inspection can tell you if they are ready to be replaced.
Save Money with Regular Maintenance
Replacing spark plugs is part of normal vehicle maintenance. Changing them before they wear out too much can help your engine run better, improve fuel mileage, and help you avoid more expensive repairs. Keeping up with scheduled maintenance is one of the easiest ways to help your vehicle last longer.
