Full-Service Engine Tune-Ups

When Should You Get a Tune-Up?

Modern vehicles need fewer tune-ups than older models, but they still benefit from periodic inspection and fresh wear items. Use these guidelines to time your visit:

Recommended intervals

  • Follow your owner’s manual and maintenance minder.
  • Many vehicles benefit from a tune-up check around 30,000–60,000 miles, with spark plug replacement commonly due between 60,000–100,000 miles, depending on plug type and engine design.

Schedule a tune-up if you notice

  • Hard starts, rough idle, or stalling
  • Reduced power or drop in fuel economy
  • Check engine light or misfire codes
  • Engine shaking, pinging, or unusual noises
  • Strong fuel smell, dirty air filter, or darkened fluids

Not sure if you need a tune-up or a specific repair? Book an inspection and we will run proper diagnostics, explain the results in plain language, and recommend the right service for your vehicle.

Frequently Asked Questions

What’s the difference between tune-ups & routine vehicle maintenance?
