Just as regular check-ups with a physician can help you stay healthy and fit for years to come, periodic car tune-ups can ensure good engine performance and keep it running smoothly. What does a tune do to a car?

That said, you might be wondering what a tune-up does to a car and what does it entails. This article covers the basics of car tune-up.

What’s a Car Tune-Up?

A car tune-up is a form of preventive service or maintenance to your car. It’s not a single, universal service that offers the same services for every vehicle or car shop.

It is generally meant to ensure that you’re getting the most from your car. This is because, parts of your engine, emissions systems, ignition, and other systems can get dirty, cracked, worn out, damaged, or get old over time.

If left unattended, the seemingly harmless dirt and wear and tear on your car’s internal components can reduce engine performance, fuel efficiency, and the life o your fuel and engine systems. Thus, it’s important to always remember car maintenance schedules and tune-ups.

In general, a tune-up is intended to replace wear and tear parts such as gaskets, fluids, spark plugs, filters, and other parts of a car that regularly wear out.

Take note that what exactly a tune-up means for you will depend on the car you drive. For instance, if you have a diesel pickup truck, you’re looking at a whole different list of parts to replace than if you’re driving a small hatchback with a gasoline turbo engine.

What Does A Tune Do To A Car?

After a tune-up, you may start to notice that your engine starts easier and runs smoother than before. Since a tune-up helps keep your fuel and engine systems and other internal parts clean and working properly as they should, your car doesn’t have to work as hard to provide maximum performance.

In addition, you may also notice an increased fuel economy after a tune-up. It’s also important to note that a tune-up can also help in reducing emissions which is great for the environment.

When To Get a Car Tune-Up?

While tune-ups are important, most vehicles don’t require them as often as they require other maintenance tasks such as an oil change.

That said, a car tune-up will depend on the regularly scheduled maintenance suggested by your car manufacturer. In general, older cars with non-electronic ignitions are recommended to be tuned every 10,000 – 12,000 miles.

For newer cars with fuel injection and electronic ignition, you can go up to 30,000 – 50,000 miles or so, without needing a major tune-up. Some manufacturers even recommend up to 100,000-mile intervals before getting a tune-up.

Signs You Need a Car Tune-Up

While we provided a general guide on when you should get a car tune-up, there may be times when a tune-up is necessary outside of the suggested manufacturer’s service maintenance schedule.

It may be time for a tune-up if you notice any of these signs in your car:

  • Your “Check Engine” light remains on or starts flickering
  • You hear a knocking sound when accelerating
  • You notice a reduced gas mileage
  • Your car’s engine sounds rough while running or stalls when the car is stopped
  • The engine has noticeable less power


How much will a tune-up cost?

The cost of a car tune-up will depend on numerous factors, including the make and model of your car and the results of the initial inspection.

Do Tune-Up Requirements Change as My Car Ages?

Yes. Tune-up recommendations can change over time since the types of things and parts that wear on a car change as they age.

What are the benefits of a tune-up?

The major benefit of getting a car tune-up is ensuring that your car functions properly and preventing or minimizing damage. Depending on what the tune-up involves, you will also benefit like increased mile efficiency, enhanced car’s efficiency and more.


Tune-ups keep your car in tip-top condition. It’s all about car diagnostics and engine maintenance so that your car operates efficiently and runs as smoothly as possible.

If you want to keep your car in top-notch condition for years to come ad avoid breakdowns, it’s important to schedule regular tune-ups with a trusted mechanic.
