Manufacturers often have routine service schedules applicable based on a vehicle’s age and mileage. Some of the more common intervals recur every 30,000 miles. A 30/60/90K service check up is designed to address maintenance and inspection items applicable to the respective mileage interval. Generally, these items may include filter changes, fluid changes and a comprehensive visual maintenance inspection as well as other items, depending on the specific mileage interval. Most modern vehicles will have received several major service requirements at 90,000 miles. Some however, may not require some of these items (Timing Belts, for example) until the next interval of 120,000 miles or beyond. We also recommend performing routine maintenance services at this time as well including an oil change, tire rotation, fluid top off and more.
