Generac Scheduled Maintenance Kit (Guardian air-cooled) Review
Oil, filters, and plugs matched to your Guardian — annual service in one box.
The verdict
Standby generators need annual service (or every 200 run-hours) to keep the warranty valid and the machine outage-ready. Generac's kits bundle the correct oil, oil filter, air filter, and spark plugs for each engine family. DIY the service in 45 minutes or hand the kit to your technician and save the parts markup.
Typical price: ~$79 (typical street price — current price shown on Amazon)

What to know
- −Verify the kit matches your engine (8kW–24kW kits differ)
- −DIY service still requires following the maintenance schedule log
Full review
A standby generator's entire value is starting unattended during the storm, and the weekly self-test doesn't change the oil. The maintenance schedule is short — oil, filters, plug, battery check, once a year — and the kit removes the parts-matching homework. Set a calendar reminder for the same week you change smoke-alarm batteries.
Best for: Guardian owners keeping service in-house or supplying their own tech.
