A car tune-up is nothing but a preventive aftercare. Performing a tune-up at the right time will discover minor problems and give the motorist a chance to fix them. A car tune-up is different from total servicing. It is a simple check-up done on the vehicle to ensure it continues to perform well. If you want to extend the life of your car, reduce the cost of repairs, improve engine performance, and get better fuel economy, then you have to follow the routine tune-up schedule.
