You could get better gas mileage—by an average of 4% or 16¢ per gallon—with an engine tune-up1

Modern engines are made up of sensitive electronic components, so they can be difficult to troubleshoot without the right equipment. During an engine tune-up, the experts at Tire & Service Network locations use an engine diagnostic tool to access your vehicle’s computer data. This data lets us diagnose any hidden performance problems or parts that need to be replaced.

The specifics of your engine tune-up service depend on what kind of vehicle you drive:

  • We start with an expert visual inspection of all your engine’s components
  • Engine diagnostics are checked to see if there are specific problems your tune-up should address
  • Your tune-up service may require the replacement of faulty components such as spark plugs, air filters, fuel filters, or other parts that shows wear
  • Adjustments to your vehicle’s idle and timing are made as needed

Engine tune-up services are backed by the by the Tire & Service Network Limited Warranty of 24 months or 24,000 mi (40,000 km), whichever comes first, for standard parts and labor.*

How do tune-ups improve my vehicle’s performance?

When you drive, heat and friction cause wear and tear on vehicle components and systems. By replacing worn or faulty parts, regular tune-ups help to maintain vehicle safety and performance. Tune-ups can help you achieve maximum fuel efficiency.

When to get a tune-up

Tune-ups should be done annually as part of your regular maintenance plan. However, you should come in for a tune-up right away if:

  • You have to fill your tank more often or your gas mileage seems to decline
  • Response, power, or torque isn’t what it used to be
  • Your vehicle runs rough or stalls out at a stop
  • Your engine knocks or pings when you accelerate or after you turn the ignition off
  • Your check-engine light turns on and stays on
