When To Change Spark Plugs ?
When to change spark plugs is something that your car auto mechanic usually doesn’t know because of all the things involved that determines whether it is time to change them. The common excepted time frame to change them is usually around 30,000 all the way up to 100,000 miles. This still is not a very good way to determine whether or not they need to be changed because it is to vague a time frame. It does not consider your specific vehicle with your specific mileage along with your vehicles specific requirements. Before we dive into all the different factors that determine when to change spark plugs, let’s first take a closer look at the spark plug and it’s importance in the optimal performance of your vehicle.
Even though it is a small part of the engine it plays a very big roll. In an internal combustion engine, it is what is used to create the spark that lights the air fuel mixture in the combustion chamber. It’s basically made up of individual components that consists of the terminal, insulator, ribs, insulator tip, seal, center electrode and metal case. Over the years there have been many improvements on the design in order to extend it’s life, provide better spark ignition or both. With the new design changes and improvements came more efficient vehicles with better fuel mileage along smoother running engines and better overall performance.
In order to keep your vehicle running at its best you will need to check the spark plugs in order to determine if they need to be replaced. The easiest way to determine if it is time to change the spark plugs is to remove a couple of them and inspect the insulator tip, which is the part that protrudes into the combustion chamber and is where the spark occurs. If the tip is tan or light grey in color then that will indicate normal wear. If there is any unusual wear, carbon build-up, oil fouled, overheated, or mechanical damage then it is time to replace the spark plugs.
Old or damaged plugs can cause all kinds of problems such as poor fuel mileage, vehicle hard to start, engine idles roughly and several other things that may eventually lead to costly repairs. It is essential to the optimal performance of your engine to know when to change spark plugs. This will not only prevent any major damage to your engine but will also keep your engine running smoothly with plenty of power and optimal fuel efficiency for many miles.
