A working fuel system is at the heart of your car's efficiency and longevity. Manufacturers seldom recommend specific service intervals for your car's fuel system. However, there are certain considerations to bear in mind.

How to Know When It's Time for Fuel System Service

When it's time for fuel system service, your car tells you. Depending on how often you drive, your driving behavior and the conditions in which you drive, your vehicle may require fuel system service more or less frequently than other vehicles. Here's what to look and listen for:

  • Slow acceleration
  • Slow engine response
  • Loss of power when towing or going uphill
  • Shudders when idling
  • Rough starts

What Does Fuel System Service Entail

Most fuel system service entails three to five steps. Your vehicle may require at least three or, perhaps, all of the steps:

  • Cleaning of the fuel injectors
  • Removal of varnish from throttle body
  • Cleaning of varnish from valves
  • Changing of fuel filter
  • Addition of fuel additive

One or more of these components may require service up to or at intervals of every 30,000 miles. Look and listen for the signs, and inquire about the need for fuel system service during routine maintenance appointments.
