The frequency of maintenance checks for vehicles can vary depending on several factors, including the make and model of the vehicle, its age, how often it’s driven, and the driving conditions. However, a general guideline is to have your vehicle serviced every 6 months, or every 5,000 to 7,500 miles, whichever comes first. More frequent checks may be needed for older vehicles or those subjected to harsh driving conditions like stop-and-go traffic or extreme weather.
