If you have a new car there is a service guideline to follow to keep your car under warranty.
If your car is older tune ups are more important.
What is most important is to listen, smell and see changes and take action. You have to find a mechanic that you can trust to be honest and still a good mechanic. That is not an easy task. Talk to others and find out what their experience is with their mechanics.
