How are maintaining your car tune-ups really affecting your car’s condition? Between outdated advice and internet rumors, it’s easy to fall for myths that cost you time, money, and even your car’s long-term health.
At GM Auto Service in Roslindale, we’ve seen it all—and we’re here to say all you need to hear about your car’s tuneup. Whether you drive a new SUV or an older sedan, these 5 car tune-up myths might be holding your vehicle back.
🛠️ Myth #1: “Modern Cars Don’t Need Tune-Ups Anymore”
Yes, vehicles today are smarter and more reliable, and might even be stronger than the previous ones. But that doesn’t mean they’re maintenance-free.
Tune-ups have evolved. While older cars needed spark plug replacements every 30K miles, newer models require:
- Air and cabin filter replacements
- Fuel system cleaning
- Battery and sensor checks
- Ignition diagnostics
📍 Even a modern vehicle needs periodic attention to maintain top performing engine, fuel efficiency, smooth acceleration, and emissions compliance.
🧾 Myth #2: “Tune-Ups Are Just a Way to Upsell You”
We understand—there’s skepticism for certain service centers from past experiences. But a true tune-up isn’t about changing everything or getting extra charges. It’s about:
- Fixing minor issues before they become major problems
- Keeping Car Fluids in the correct level
- Improving engine performance
- Extending vehicle life
At GM Auto, our technicians only recommend what your car actually needs—nothing more, nothing less. No hidden fees!
🔌 Myth #3: “If My Car Runs Fine, I Don’t Need a Tune-Up”
Not all running vehicles means they are in their prime. They might be holding back issues that might get worse in time.
Minor issues like:
- Low fluid levels
- Dirty spark plugs
- A clogged air filter
can go unnoticed for weeks or months—until they start affecting your gas mileage, power, or even emissions. Even worse, they might have a negative effect on your engine.
Preventative tune-ups save money in the long run and keep your vehicle ready for daily driving or summer road trips.
🌬️ Myth #4: “Air Filters Don’t Really Matter”
Actually, they do. Replacing your engine air filter improves:
- Fuel economy
- Horsepower
- Overall engine health
And don’t forget your cabin air filter—it’s what keeps the air you breathe inside the car clean. It also protects your AC system, especially during hot Boston summers.
Filters are part of every quality tune-up service at GM. Not only your car, but your health will be considered for this part.
⚡ Myth #5: “You Can DIY Every Part of a Tune-Up”
While checking your fluids or replacing wipers is available for DIY, modern vehicles require computer diagnostics to:
- Read engine codes
- Adjust ignition timing
- Check sensor outputs
Unless you’re equipped with professional-grade tools (and the training to interpret results), it’s best to trust a certified technician for better accuracy and diagnosis.
