Every 30,000 miles or every three months—whichever comes first—you should take your vehicle into a mechanic for inspection. The inspection will determine which services your vehicle needs at that point, and your mechanic can then perform the appropriate services. While every vehicle is different, there are some services that most cars will require every 30,000 miles or so.
Most vehicles, for example, will need to have the automatic transmission fluid checked at this point. During a properly performed check, your mechanic will turn the vehicle on, put it in park, and then check the fluid level. If the fluid level is low, your mechanic will use a quality fluid that is appropriate for your particular vehicle to replenish it. Your oil and oil filter should be checked and, if necessary, changed at this point as well.
The 30,000 mile mark is also a good time to have your tires examined. Tire pressure should be checked, and when necessary, each tire should be inflated to the correct pressure amount, which will vary from one vehicle to the next. If your tires are found to be particularly worn or damaged, some or all of them may need to be replaced at this time in order to maintain safety and to enable your vehicle to pass its state inspection. This is also a good time to have your tires rotated.
Your battery needs to be inspected at this point too. An experienced mechanic will ensure that the battery is properly mounted, properly connected, and free from rust or other damage. Batteries should be tested to ensure they are working correctly and, if they are not, a replacement may be in order. How often you will need to replace your battery will depend on several different factors, but most drivers will require this service once every three years or so.
These are just a few of the services your vehicle may require at 30,000 miles. Other services that may need to be performed include timing belt replacements, checking of the engine oil and filter, examination of all car lighting, and more.
