tune up is like spring clean up, once a year....
every 3,000 miles
Most cars built in the last 20 years need a tune-up at around 80-100,000 miles.
Should only be required at 100,000 miles
The manufacturer recommends that you tune up your 2005 Ford Taurus every 30,000 miles. The tune up should include replacing the spark plugs, spark plug wires, and cleaning the fuel injection system.
Refer to the owners manual for the recommended frequency of service and tune-ups. Tune-ups are usually scheduled at specific intervals based on mileage.
tune it up
That depends on the car. Some vehicles with points in the distributor needed a tune-up every 10,000 miles. Solid state ignitions have changed that number and many of the GM vehicles are advertising that you don't need your first tune-up for 100,000 miles. Refer to the owners manual for the recommended interval between tune-ups.
every 30,000 miles every 60K
follow owners manual,25 to 30,000 is usually good.
