What Is Needed?
The car's service manual is the best way to learn how to maintain your car. It was written by the factory representatives who designed and built the car. It stands to reason that they should also know how best to keep everything running smoothly.
Some vehicles will even have a reminder display indicating that a service, typically an oil change, is required at a certain mileage point. Still other vehicles will use a "maintenance minder," which will only become illuminated when the work is actually required. A computer in the car's engine makes a calculation based on a number of factors that more accurately determine the time at which oil begins to break down.
