In a troubled economy, many people look for ways to cut costs by doing household tasks themselves. Some automotive jobs can be done fairly easily at home, particularly if you know something about cars. However, taking on the wrong job on your own will only cost you more time, stress and money in the long run. My name is Jill, and I want to tell you about which car maintenance tasks you can safely tackle on your own and which really do require some help from a pro. I'll break down the needs of a typical car and tell you exactly why you might need to ask for help sometimes.
