Should You Lubricate Spark Plugs? Essential Tips for Optimal Performance

Discover the best practices for spark plug maintenance and why lubrication can affect performance.

0 views

Do not lubricate spark plugs directly. For best performance, apply a thin layer of anti-seize compound to the threads to prevent them from sticking or corroding. Be cautious to avoid getting any on the electrode or insulator as it can affect spark plug operation. Always follow manufacturer-recommended practices for optimal results.

FAQs & Answers

  1. What is the purpose of anti-seize on spark plugs? Anti-seize compound prevents spark plugs from sticking and corroding, ensuring easier removal and better installation.
  2. Can I use oil instead of anti-seize on spark plugs? No, using oil can damage the spark plug's components and affect its performance; always use anti-seize as recommended.
  3. What happens if I put lubricant on the electrode of a spark plug? Lubricant on the electrode can interfere with the spark plug's operation, leading to poor engine performance.
  4. How often should I check my spark plugs? It's advisable to check spark plugs every 30,000 to 100,000 miles, depending on vehicle and manufacturer recommendations.
