Replacing a spark plug is one of of the task on your car tune-up checklist. It is a high voltage bridge for electricity. When the electricity crosses the "bridge" (which is actually a gap between two contact points) inside your engine, the spark it makes ignites the gas vapors, which makes the engine running.
So how do you know when you need new spark plugs?
- Getting low gas mileage - If the spark plugs are worn down and corroded by burns and carbon deposits, they will hurt your engine performance and efficiency, resulting in low gas mileage. This is usually the first thing you should look at when you start getting poor gas mileage.
- Getting hard starting or rough idling - Worn or corroded spark plugs can be a factor to this. However, fuel injectors being dirty can also be attributed to this problem. Spark plug is often the first thing you should look at.
- Time between last spark plugs change - Check your owner's manual or factory service manual for the correct time or mileage when it comes to spark plugs replacement. If you don't know when your spark plugs last time changed, you can pull out the plugs and check for wears and/or any carbon deposits.
Refer to your owner's manual or factory service manual for better procedures on how to replace your spark plugs. In most cars, changing the spark plugs is easy and fast. Before you start, make sure you have the following tools ready:
- Ratchet wrench
- 12-in socket extension

Changing Engine oil is perhaps one of the most important car maintenance on your checklist. Fresh and clean engine oil can ensure your engine run smoothly. When you change your engine oil, it's also important that you replace your oil filter as well. Most people choose to take their car to the local shop for oil change. However, changing your own engine oil is very simple, and you can save a little bit of more money if you choose do it yourself. If you have a car jack and couple of simple tools, you are ready to change your own engine oil. Make sure you buy the correct engine oil weight and oil filter for your car's engine. If you do not know which type of oil and oil filter to buy, you can often refer to your car's owner's manual or factory service manual to get the specification. If you don't have either manuals, you can also call your local car manufacture or stores like Schucks for the same information. Watch the video below to learn more on how to change your engine oil:
