The Essential Guide to Spark Plug Maintenance: Keeping Your Engine in Peak Condition

Orient Auto Service • July 26, 2025

At Orient Auto Service in Gresham, OR, we believe that a well-maintained vehicle is not just about longevity but also about performance and safety. One of the often-overlooked components in many vehicles is the humble spark plug, a small but crucial element that ensures your engine runs smoothly and efficiently.

Understanding Spark Plugs

Spark plugs are essential in igniting the air/fuel mixture in your engine's combustion chamber. This ignition process is crucial for starting your car and keeping it running. With so many types of spark plugs on the market, including copper, iridium, and platinum, choosing the right one for your vehicle can enhance performance and fuel efficiency.

The Importance of Regular Spark Plug Maintenance

At Orient Auto Service, our experienced technicians in Gresham, OR, have often witnessed the impact of neglected spark plug maintenance. Worn or dirty spark plugs can lead to numerous engine problems, including poor fuel economy, hard starts, and misfires. Regular inspections and replacements are vital to maintaining your car's overall health.

Signs Your Spark Plugs May Need Attention

For those of us at Orient Auto Service, recognizing the signs of worn-out spark plugs is a key part of vehicle maintenance. Pay attention to:

  • Engine Misfires: A clear indicator that your spark plugs might be failing is irregular engine idling or starting issues.
  • Poor Acceleration: If your vehicle isn't accelerating as swiftly as it used to, worn spark plugs could be the culprit.
  • High Fuel Consumption: Noticing more frequent trips to the gas station? Spark plug inefficiency could be a factor.

How Often to Check and Replace Spark Plugs

While recommendations can vary by manufacturer, a general rule of thumb we follow at Orient Auto Service is to inspect your spark plugs every 30,000 miles. For certain modern vehicles, this interval may extend up to 100,000 miles with premium iridium or platinum spark plugs.

Steps for Spark Plug Maintenance

While we always welcome you to bring your vehicle into Orient Auto Service for professional maintenance, here's a simple overview of what spark plug maintenance often involves:

  1. Locate and Remove: Carefully remove the old spark plugs, ensuring not to damage surrounding wires and connectors.
  2. Inspect and Clean: Examine each plug for wear and tear. Cleaning involves removing any carbon deposits or build-up that could affect performance.
  3. Gap Check: Before installation, ensure the plug gap is correct, following manufacturer specifications for optimal performance.

Choosing the Right Spark Plugs for Your Vehicle

Spark plug selection can be daunting with so many options available. At Orient Auto Service in Gresham, OR, we recommend consulting your vehicle's manual or speaking to our team to ensure compatibility with your car model and engine type.
