A standby generator may run only during tests and outages. Follow the engine maker’s calendar limits for oil, coolant, and filters, and your facility’s testing program, such as NFPA 110 where it applies.
Protect the fuel
Fuel quality is often the weak point in emergency power. Sample stored fuel periodically, drain water, and keep records alongside generator test logs.
Products by equipment.
Confirm the lubricant type, grade, and specifications in each equipment manual before ordering.
Diesel generator engines
Match the engine maker’s API category, viscosity, and approvals. Standby engines may age oil by time rather than hours.

Frequently asked questions
How often should standby generator oil be changed?
At the engine maker’s hour or calendar limit, whichever comes first. Oil analysis can help confirm condition between changes.
Can stored diesel go bad?
Stored diesel can collect water, sediment, and microbial growth. Periodic fuel testing helps identify problems before an outage.
