Written from the listing's specs, not from our own use · How we rate
The Generac 6484 Maintenance Kit ticks most of the boxes we care about: parts for 12 to 18 kW units and 5W-30 synthetic oil. Think of it for the yearly service of a home standby unit: 7.4/10 on what its listing documents.

Our take
The Generac 6484 Maintenance Kit earns its place with parts for 12 to 18 kW units and 5W-30 synthetic oil. No buyer reviews yet, so this Generac maintenance kit has to win you over on paper. The catch with the Generac: it only fits the models it lists, so check your model before you order. We'd pick it if you own a home standby unit it lists; otherwise, put it next to the Generac 6485 Maintenance Kit first.
Before you order the Generac 6484 Maintenance Kit, check your model number: it is listed for specific units, and fit is model-specific.

Both score 7.4/10. Compare the listings side by side to choose.
