The Two Instances When You Should Always Replace Your Spark Plugs



Let's talk spark plugs. A common question we hear at Grayson's Auto Service is, "Should I replace my spark plugs?"

A spark plug performs a critical task for your vehicle's engine. Without a spark plug your car or truck's engine cannot work. Properly working spark plugs also deliver added fuel efficiency. Most owners manuals say to replace the spark plugs every 80,000 to 100,000 miles. In many cases spark plugs last longer than the driver's ownership of the car.

So, when should you replace your spark plugs?

1. If you just purchased a used vehicle
2. At least every 80,000 miles

Spark plugs are one of the hardest working parts of a vehicle. If you just purchased a used car, it is best to go ahead and replace the spark plugs. You have no idea if the previous owners were "severe" drivers. A spark plug can fire 400 times per minute per cylinder or 1,600 times a minute on a four-cylinder engine. Severe driving can place even higher demands on the spark plugs and engine.

Many used car dealers boast an extensive multi-point inspection plan prior to the sale of any car but many of these plans don't cover spark plug integrity. Because a failed spark plug can mean disaster for your new purchase it is best to get them replaced by the qualified technicians at Grayson's Auto Service in Wilson.

At Grayson's Auto Service we recommend replacing spark plugs before they reach the 80,000-mile mark. Many car owners delay spark plug replacement until the engine starts "missing." An engine that is "missing" will typically result in a jerking feeling when accelerating. Spark plugs that are severely worn out will create a pinging or knocking sound. These fouled, worn-out spark plugs can lead to extensive engine damage that is expensive to fix. Therefore, replacing spark plugs before they reach the 80,000-mile mark is very important.

Three Indicators Your Spark Plugs Need To Be Replaced

1. Rattling, pinging or knocking noises when accelerating
2. Missing, hesitating or jerky feeling when driving
3. Slow acceleration or chugging

Sluggish and reduced performance also causes poor fuel economy. Save money at the pump by taking care of your vehicle's spark plugs.
