For those who aren't that mechanically sound, understanding car servicing becomes challenging. However, you should know the basics when you take your car to the mechanic. You want to make sure you get it back in top condition from a safety and functionality point of view and also understand what happens to your car while it is there. Most cars have a minor and major maintenance scheduling cycle. The minor services usually take place every 10,000 - 15,000 km while the major servicing process is done around every 30,000 - 45,000 km depending on the model and make of the car, on how it has been driven, and the mechanic's recommendations.
