Now's the time to get your car up to speed on all of its regular maintenance. That means taking care of any fluids that may have been neglected while you were out enjoying the summer sun or going in for that 60,000-mile tune-up if you're due. Check, change and/or top off your oil, coolant, and brake and transmission fluid as needed. In the case of your oil or automatic transmission, make sure you get a high-quality filter, too. It may seem like overkill to take care of all of your fluids at once, but it's worth it in the long run.
