If you don’t change your spark plugs, a few things could happen. Your car could have trouble starting, decreased fuel efficiency, and reduced power. You might also notice your engine running rougher than usual.
Over time, not changing your spark plugs can cause serious damage to your engine.
How To Tell When You Need New Spark Plugs
If you don’t change your spark plugs, your car’s engine will eventually stop running. The spark plugs are what allow the engine to ignite the fuel and keep the car running. Over time, they will become fouled with deposits and will no longer be able to create a spark.
This will cause the engine to misfire, run rough, and eventually stall.
Signs You Need New Spark Plugs
If your car is experiencing any of the following symptoms, it’s a good indication that you need new spark plugs:
1. Your car is having trouble starting.
2. Your car is idling roughly.
3. You’re noticing decreased fuel efficiency.
4. Your car is losing power while accelerating.
5. You’re hearing strange engine noises.

How Long Can You Go Without Changing Spark Plugs?
How long you can go without changing your spark plugs depends on the make of your vehicle and how often you drive it. The average lifespan of a spark plug is around 20,000 miles, but this can vary depending on the type of engine and driving conditions. If you regularly drive in stop-and-go traffic or dusty conditions, for example, your spark plugs may need to be changed more frequently.
If you’re not sure when your spark plugs were last changed, it’s a good idea to have them checked at least once a year by a qualified mechanic. They can tell you if they need to be replaced and can do the job quickly and easily.
What Happens If You Don’T Change the Spark Plugs?
If you don’t change the spark plugs, your car’s engine will eventually stop running. The spark plugs are what ignite the fuel in the engine, so without them, the engine can’t run.
What are the Symptoms of a Bad Spark Plug?
If your car is having trouble starting, or the engine is misfiring, it could be a sign of a bad spark plug. Other symptoms of a faulty spark plug include a decrease in fuel economy, loss of power while driving, and an increase in exhaust emissions. If you notice any of these problems, it’s important to have your car checked by a mechanic to see if the spark plugs need to be replaced.
Do I Really Need to Change Spark Plugs?
It’s a good idea to change your spark plugs every few years, or as recommended by your car’s manufacturer. Over time, spark plugs can become fouled with oil, carbon deposits or other debris, which can prevent them from sparking properly. This can lead to engine misfires and decreased performance.
Replacing your spark plugs is a relatively simple and inexpensive task that can be done at home with the right tools.
Conclusion
If you don’t change your spark plugs, your car will eventually have trouble starting and running properly. The spark plugs help ignite the fuel in the engine, so if they’re not working correctly, the engine won’t run as efficiently. You may also notice that your car is using more fuel than usual.
