The owners manual on every vehicle should state how often the manufacturer recommends that you tune up cars, but as a general rule it is every two years or 30,000 miles, whichever comes first. Driving under extreme temperature and weather conditions will make parts wear out faster, however.
1 For older vehicles, a 90,000-, 100,000- or 120,000-mile tune-up can cost $500-$1,200 or more, depending on the repairs and adjustments needed. 2  Smith Specialty Automotive in Kansas lists what might be included in a 120,000-mile major servicing and tune-up. Total costs generally depend on the parts needed as well as the hourly labor rate (typically $40-$90 in standard repair shops or $80-$150 at a dealership).
