I've been using NAPCO for the past 5 years in Babylon and now in Wading River. The discount and service has been outstanding.   -Larry Farone

I have been a customer of NAPCO OIL for approximately 6 years. During this time I have found them to be exceptional in both delivery and service.   -William Dempsey

I have been using NAPCO for a few years and I would recommend NAPCO to anyone for their oil heating needs. I am very satisfied with their service and they don't make you pay extra for a service contract like most other oil companies.   -Chris Adamson
