The frequency of car servicing depends on several factors such as the make and model of the car, its age, how often it is used, and the type of driving it is subjected to.

As a general guideline, most car manufacturers recommend servicing your car every 12 months or every 12,000 miles, whichever comes first. However, this can vary depending on the specific make and model of your car, so it's always best to consult your owner's manual for the manufacturer's recommended service intervals.

If you do a lot of city driving or your car is subject to harsh driving conditions (such as extreme temperatures, dusty roads, or heavy towing), you may need to service it more frequently. On the other hand, if you do a lot of highway driving, you may be able to go longer between services.

It's also important to keep an eye on your car's maintenance indicators, such as the oil change reminder or the check engine light. If any of these indicators come on, you should have your car serviced as soon as possible.

In summary, the frequency of car servicing varies based on a number of factors. To ensure your car runs smoothly and stays in good condition, consult your owner's manual and pay attention to any maintenance indicators.
