How Often Should You Change Your Generator's Oil?

MALL Energy Home • April 29, 2025

Regular oil changes are crucial for maintaining the reliability and longevity of your standby generator. In East Texas, where extreme weather can lead to frequent power outages, ensuring your generator is in top condition is essential. MALL Energy Home offers professional generator maintenance services in Longview and surrounding areas, making it easy for homeowners to keep their backup power systems ready when needed.​

🛢️ How Often Should You Change Your Generator’s Oil?

The frequency of oil changes depends on the type of generator, usage, and manufacturer recommendations. For most standby generators:​

  • Initial Break-In Period: Change the oil after the first 20–30 hours of operation.

  • Regular Use: Every 100–200 hours of operation or at least once a year.

  • Heavy or Extended Use: Every 50–100 hours, especially during prolonged power outages.​

Always consult your generator's manual for specific guidelines.

⚙️ Why Regular Oil Changes Matter

Oil lubricates the engine, reduces friction, and helps dissipate heat. Over time, oil degrades and becomes contaminated, leading to increased wear and potential engine failure. Regular oil changes:​


  • Ensure optimal performance
  • Extend the generator's lifespan
  • Prevent costly repairs​
