Many auto experts rank an auto tune up just below an oil change in terms or important maintenance. There is not a standard mileage figure (because there are too many variables). You can often go 30,000 miles or so before it's time for a tune up. An auto tune-up can pay off in greater fuel economy, improved engine performance, cleaner air, and fewer expensive repair bills. Regular tune-ups can extend the life of your vehicle.

 

Now, what constitutes a tune-up? There isn't a single definition. What might be included in an older vehicle tune up, may not apply to a newer car.

 

Here is a list of some basic tune-up items:

• Replacing spark plugs

• Replacing the fuel filter

• Cleaning or replacing air filters

• Cleaning throttle body

• Cleaning or replacing PCV valve

• Inspecting or replacing spark plug wires

• Inspecting or replacing distributor caps and rotors

• Inspecting or replacing hoses and belts

• Inspecting or replacing the oxygen sensor
