Scheduled Maintenance Intervals


Every car needs maintenance if you intend to have it last for the long haul. Many manufacturers are increasing the mileage interval of services, or simply omitting fluid changes from their list of maintenance items. They do this to decrease the annual cost of ownership line-item on the new car sticker, making the vehicle more attractive to fleet purchasers and allowing television boasting. The systems haven’t changed, only the recommendations have. Consumers are led to believe this because it further helps new car sales, and also lets dealership service departments provide cheap initial estimates. After you arrive for your cheap service, you receive a phone call up-selling you every item that should have been pre-sold.
