Need a little spark in your life?

The technicians at the SVG Service Department would like to remind you that the concept of preventive maintenance isn't to repair your vehicle when it breaks, but to keep it from breaking down in the first place. One of the most affordable things you can do to prevent engine issues is to replace your spark plugs when the vehicle manufacturer recommends. Some vehicles may only need spark plugs replaced every 50,000 miles. Check your owner's manual to see when your vehicle is due. We've often found that replacing spark plugs a little earlier than recommended can help improve engine performance and restore some lost fuel mileage, too. Want to know why spark plugs are so important? Read on.

Your spark plugs fire as many as 3 million times for every 1,000 miles driven. Each "spark" is like a miniature lightning bolt - it's truly that powerful! Imagine an electrode being zapped by lightning millions of times and you'll quickly understand why spark plugs need to be replaced. Every single spark removes a tiny bit of material from the electrode, reducing its effectiveness. Each spark also produces intense heat and chemical corrosion. Over time, your spark plugs just plain wear out from sacrificing themselves to perform their job.

In the image below, you can see the difference between a new and used spark plug and imagine how that can affect your vehicle's performance. These spark plugs were in a BMW.

Here's what can happen when your spark plugs start to wear out:

1.) They can get dirty, leading to misfires.
2.) They don't ignite the fuel as well, causing you to get poor fuel mileage.
3.) Because they aren't firing properly, your engine performance can suffer (slower acceleration among other problems).
4.) Prolonged misfires can damage ignition coils leading to costly repairs.

If you want to avoid costly future repairs, check your owner's manual and find out when your plugs should be replaced then come see the service technicians at SVG. If you're not sure when your plugs need replaced, call us. We'll be able to find out for you.
