Our take
The Generac 6485 Maintenance Kit is about 5W-30 synthetic oil, and it doesn't pretend to be more. No buyer reviews yet, so the Generac 6485 Maintenance Kit has to win you over on paper. The catch with this Generac maintenance kit: it only fits the models it lists, so check your model before you order. We'd pick it if you want a maintenance kit for owners who service their own standby generator; otherwise, put it next to the Generac 6484 Maintenance Kit first.
Before you order the Generac 6485 Maintenance Kit, check your model number: it is listed for specific units, and fit is model-specific.
Find the full model number on your generator's label and compare it with the listing before you order.
The manual says how often (hours or months). Our maintenance schedule lays out a simple routine.
