Should I Replace My Car’s Spark Plugs?

Share it

Let’s discuss the situations in which it is advisable to replace your spark plugs:

  1. When you purchase a used vehicle: If you have recently acquired a used vehicle, it is highly recommended to replace the spark plugs. Spark plugs play a critical role in your vehicle’s engine, and without them, the engine cannot function properly. Furthermore, replacing worn-out spark plugs can enhance fuel efficiency. Since you may not be aware of the previous owner’s driving habits, it is better to err on the side of caution and have the spark plugs replaced. Severe driving conditions can put additional strain on spark plugs and the engine, making replacement a wise decision.

  2. At least every 80,000 miles: In general, most owner’s manuals suggest replacing spark plugs every 80,000 to 100,000 miles. However, it’s worth noting that spark plugs often outlast a driver’s ownership of the vehicle. To ensure optimal performance and prevent potential engine damage, it is advisable to replace spark plugs before they reach the 80,000-mile mark. Delaying replacement until the engine starts exhibiting issues such as jerking during acceleration, rattling, pinging, knocking noises, hesitation or a sluggish feeling while driving, or slow acceleration can lead to more severe problems. Severely worn-out spark plugs can cause engine damage and expensive repairs.

By replacing spark plugs before reaching the recommended mileage or if you experience any of the aforementioned indicators, you can improve your vehicle’s performance, fuel economy, and avoid potential engine complications.
