Change the oil & filter every 5,000 miles is my recommendation unless you are using synthetic oil. If that is the case change it every 7,500 miles. Use a quality filter such as Wix, or Purolator, and use the exact weight oil Honda recommends. More than likely 5w20. Look in the owner's manual to be sure or it may be listed on the oil fill cap.

You need oil
You should change the air filter in your Honda Civic when it is dirty or at every second oil change. Most filters will last for two oil changes through standard daily driving.
The starter on a Honda Element is located on the bottom of the engine near the oil pan. It rotates the engine during the starting process.

My 2004 Honda uses 5w-20 . Use a good quality detergent oil listed for gasoline engines.
