Back in the day, an auto tune-up was something you did annually to ensure your vehicle would operate at its fullest potential throughout the year. Typically, they would replace spark plugs, condenser, rotors, and nearly everything else in the car’s ignition system that is susceptible to everyday wear and tear. Additionally, they would also replace the air filter and fuel filter and clean out the choke to make sure your engine starts quickly, especially during the cold winter months. Nowadays, many of those systems no longer exist in cars because new fuel and ignition systems work exceptionally well and may not require maintenance as frequently. Tune-ups, though, are far from a thing from the past, and all cars, trucks, and SUVs still need preventative maintenance every 50,000 miles or so to ensure the vehicle’s performance. However, because vehicle performance doesn’t degrade as rapidly as it once did, many people frequently forget to have their cars tuned up until a significant issue arises.
