Gasoline powered generators should be tested and run for:

• A. 15 to 30 minutes
• B. 2 to 3 minutes
• C. 5 minutes
• D. At least 1 hour

Answer: (A)

Gasoline engines need to be exercised for a period that allows them to warm up and operate under normal conditions. Running a generator for about 15 to 30 minutes does that effectively: it brings the engine up to operating temperature, stabilizes oil pressure, and lets the electrical system reach steady voltage and frequency. This duration gives you a true check of starting reliability, fuel delivery, cooling, and overall readiness, while avoiding unnecessary fuel use or wear from an overly long run. Short runs may not reveal issues that only show up after the engine warms, and running for an hour isn’t needed for routine testing. So, 15 to 30 minutes is the appropriate test and run time.
