Exactly What You Need For 24k Genny
By John V

Purchased 08/06/2024 |
Review Posted 08/28/2024
Super helpful customer service to narrow down exactly what I needed. The parts are legit OEM from Generac, the paper towel and funnel is a gracious inclusion. I need more than one paper towel to make the oil change. I would classify that as part of the process. Buy this with confidence.

GOOD COMPANY SERVICE,QUALITY AND DELIVERY
By Todd L
New York
Purchased 10/23/2023 |
Review Posted 11/14/2023
Bought 4 kits, as I change oil and filter 2 times a year, good products, towel and funnel are a plus. You will need a empty bottle for old oil, Run your generator for 5 min to warm the oil before changing, purchased syn oil locally. The spark plugs are nice, However if you change oil regularly you wont need but 2 every couple years unless your generator runs a lot.
