The Complete Car Maintenance Schedule: What to Do and When for Any Vehicle
The gap between what dealership service departments recommend and what vehicle manufacturers specify in owners’ manuals represents a significant amount of unnecessary spending for many vehicle owners. Many service items recommended at every oil change — fuel system cleaning, throttle body cleaning, transmission fluid service on vehicles with very low mileage — either don’t match the manufacturer’s specified interval or apply only under severe service conditions that most drivers don’t experience. Here is the manufacturer-based maintenance schedule that applies to most modern vehicles under normal operating conditions.
Every 5,000 to 7,500 Miles (or Annually)
Oil and filter change — the most important scheduled maintenance on any vehicle. Tire rotation — extends tire life significantly at minimal cost. Visual inspection of brakes, belts, and fluid levels. These three items constitute the majority of routine maintenance value for most vehicles in normal use.
Every 15,000 to 30,000 Miles
Engine air filter inspection and replacement if dirty. Cabin air filter replacement — affects HVAC performance and in-cabin air quality. Brake fluid inspection and replacement if degraded (test strips available at auto parts stores). Battery load test — particularly on batteries over three years old.
Every 30,000 to 60,000 Miles
Spark plug replacement — iridium and platinum plugs last 60,000 to 100,000 miles; copper plugs last 30,000 miles. Coolant flush and refill. Transmission fluid service on most vehicles — check your owner’s manual for the specific interval. Fuel filter replacement on vehicles with external filters. Serpentine belt inspection and replacement if showing cracking or glazing.
Every 60,000 to 100,000 Miles
Timing belt replacement if the vehicle has a timing belt (as opposed to a timing chain) — this is a critical interval. Timing belt failure on an interference engine causes catastrophic valve-to-piston contact that destroys the engine. Confirm whether your engine has a belt or chain — the owner’s manual or your vehicle’s service data will specify. Drive axle CV boot inspection and replacement if torn.
