An in depth car maintenance check should be performed with every oil change service that is performed, no matter how new or old the vehicle is. Harsh driving conditions and habits can speed up wear and tear on a number of vehicle systems and parts. Tire defects, when caught early, can be rectified before they are able to cause problems with your car’s suspension. Brake system leaks can be found before they cause brake loss. Parts do fail before reaching design limits. Catching these defective parts early helps ensure they aren’t able to cause the failures of other parts.
