Common tasks involved in maintaining a vehicle
- Inspection - vehicle components are visually inspected for wear or any leaks. A diagnostic is performed to identify any electrical components reporting a failure or a part operating outside of normal conditions.
- Replacement - Given certain lubricants break down over time due to heat and wear, manufacturers recommend replacement. Any parts that are close to their expected failure are replaced too to avoid a failure while operating the vehicle.
- Adjustments - as vehicle components wear, they may need adjustment over time. Example: parking brake cable.
The completed services are usually recorded in a service book or digital service record upon completion of each service. A digital service record is an online record of a vehicle's maintenance history. A complete service history usually adds to the resale value of a vehicle.
Difference between major and full service: a major service is more comprehensive than a full service; although it covers all the same checks that a full service does, a major service will be more detailed and will include more replacements of wearable parts, such as pollen filters, and changing brake fluid if required.
As a guideline, minor car services are carried out every 10,000 to 15,000 kilometres (6,200 to 9,300 miles), and major car services every 30,000 to 45,000 kilometres (19,000 to 28,000 miles) – or every twelve months, whichever comes first.

Scheduling
The actual schedule of car maintenance varies depending on the year, make, and model of a car, its driving conditions, and driver behavior. Carmakers recommend the so-called extreme or the ideal service schedule based on impact parameters such as
- the number of trips and distance traveled per trip per day
- extreme hot or cold climate conditions
- mountainous, dusty, or DE-iced roads
- heavy stop-and-go vs. long-distance cruising
- towing a trailer or other heavy load
Service advisers in dealerships and independent shops recommend schedule intervals, which are often in between the ideal or extreme service schedule.
In addition, drivers may be penalized for not regularly servicing their cars. For example, in many states in the U.S., a car has to pass a safety inspection test every year or two years to remain legal, and can incur fines for continuing to drive cars that have failed.
Common maintenance
Maintenance tasks commonly carried out during a motor vehicle service include:
- Change the engine oil
- Replace the oil filter
- Replace the air filter
- Replace the fuel filter
- Replace the cabin or a/c filter
- Replace the spark plugs
- Check level and refill brake fluid/clutch fluid
- Check Brake pads/Liners, Brake discs/Drums, and replace if worn out
- Check level and refill windshield washer fluid
- Check Coolant Hoses
- Check the charging systems
- Check the battery
- Check level and refill power steering fluid
- Check level and refill Automatic/Manual Transmission Fluid
- Check suspension components shocks/struts etc.
- Check steering components inner/outer tie rods
- Grease and lubricate components
- Inspect and replace the timing belt or timing chain if needed
- Check condition of the tires
- Rotate Tires
- Check for proper operation of all lights, wipers, etc.
- Check for any error codes in the ECU and take corrective action.
- Use a scan tool to read trouble code.
Mechanical parts that may cause the car to cease transmission or prove unsafe for the road are also noted and advised upon.
In the United Kingdom, few parts that are not inspected on the MOT test are inspected and advised upon a Service Inspection, including clutch, gearbox, car battery, and engine components (further inspections than MOT).
