## What is Generator Log & Maintenance?

A generator that hasn't been run in months is a generator that fails during an outage. Generator Log keeps portable and standby generators ready - no smart hardware required.

HOUR METER
- Every run test and outage use adds to a running hour meter, shown as an odometer on each generator's page
- Oil changes and service come due by hours OR calendar time (defaults follow common manufacturer guidance: first oil change at 25h, then every 100h or 12 months - fully editable)

MONTHLY RUN TEST
- One tap logs the 3-point check: starts OK, voltage OK, no unusual noise
- A monthly reminder keeps the habit alive

FUEL MANAGEMENT
- Log stabilizer and fuel rotation, with a countdown until your stored gasoline should be replaced

MULTIPLE GENERATORS
- The garage standby and the camping portable, each with its own hour meter and schedule

SERVICE HISTORY PDF
- Export the full history - handy for warranty claims or when selling the unit
