The car engine begins to wear out over time and this aging process brings about some changes in the car. This reduces the efficiency of the car and demands the engine to be tune-up.
Tune-up durations differ with cars. While older cars that are non-electronic ignitions should be given a tune every 10,000 to 12,000 miles or every years, newer cars with electronic ignition and fuel injection systems are allowed to run from 25,000 miles to as much as 100,000 miles without a major tune-up.
However it is nice to consult the owner’s manual for recommended tune-up time intervals, but note that even if the manual fails to recommend a schedule of tune-up, it’s advisable to check periodically that the car is working at great efficiency. If the vehicle does a lot of stop-and-go driving or pull heavy loads, the ignition system may need to be tuned often.
