Everyone has to deal with auto repairs at some time in their life. Car repairs can cost a significant amount of money. Whether you are doing the repairs yourself or hiring a mechanic, it is a good idea to know what you are doing. Use these tips to be better prepared when you have to fix your car.

Save fuel by driving as if you have a glass of water sitting on your dashboard. This practice helps you avoid jack rabbit starts and quick stops. Each time you accelerate quickly, the engine of your car uses more fuel than it would if you were to accelerate at a gradual increase in speed.

Preventative maintenance is very important if you own a car. Do not hesitate to spend money on the tools you need to inspect and maintain your car or having a mechanic look at your car regularly. Maintaining your car regularly could help you save a lot on repairs or towing if your car breaks down.

Keep your car's owner manual handy. Knowing vital car information can really help when something unexpected occurs. If you know your car's controls, you may even avoid a trip to a mechanic. If you do need a mechanic, you should have the make, model, and trim level available so that they can figure out things like your transmission configuration, size, etc. much quicker.

If your car's electrical system is behaving strangely, try cleaning the ground cables. Auto makers use the metal body of a vehicle to act as a "ground" for the electrical system. Over time the area where this cable connects to the frame can corrode, causing a stray electrical current that can wreak havoc on your system. This cable is usually connected on the firewall or fender, so simply disconnect it and use a wire brush or sandpaper to clean the contacts.

Understand how the repair shop you are considering charges before signing any agreements. Some shops will charge a flat fee for labor, while others base it off of time. Some will opt for original parts, while others will use generics. Know what you have ahead of you before being accountable.

One of the best ways to save money is by being informed about car maintenance and repairs. Some mechanics take advantage of those with little car knowledge. Use the advice you learned here to either do the repairs yourself or be better armed against shady mechanics. You can save thousands over a lifetime.
