For 20 to 26 kW standby units

The unit size the listing names. Check the model number and the engine size on your generator's label first: kits for the same kW range still differ.

What it has going for it

What changes on service day

For 20 to 26 kW. Oil, filter and plugs for one scheduled service, matched to the 999 cc engine. Check your model number and engine size first.

5W-20. The grade your manual asks for, already in the box. One less trip to the store.

Do it yourself or book a service?

Do it yourself: the kit is listed for 20 to 26 kW standby units, with 5W-20 oil in the box. Oil, filter and plugs are an afternoon with basic tools.

Book a service: if the unit is still under warranty, check whether the maker wants a dealer stamp in the service log first.

Our take

The verdict

We like the Generac 5W-20 Kit for 20-26kW for parts for 20 to 26 kW units and 5W-20 oil. No buyer has reviewed it yet, so our 5.6/10 comes from the spec sheet alone. 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 own a home standby unit it lists; otherwise, put it next to the Generac 0J93230SSM Maintenance Kit first.

The one thing we'd check first

Before the Generac 5W-20 Kit for 20-26kW ships, check your model number: it is listed for specific units, and fit is model-specific.
