Why Great River homeowners choose us

South Shore warmth you can trust

Tucked along Suffolk County's South Shore, Great River is a close-knit community that values dependable service, and OK Petroleum has provided exactly that since 1976. Our long history of home heating oil delivery on Long Island means Great River homeowners can order with confidence, knowing their oil will arrive when promised.

Clear pricing is central to how we work. We confirm a transparent per-gallon rate before you check out, so there are no hidden fees and no unpleasant surprises on your invoice. You can order anywhere from 50 to 500 gallons of heating oil, or opt for a full fill, and the price we quote is the price you pay.

As a family-owned Long Island company, we answer our own phones and dispatch our own local drivers, so you never get lost in a call center. Most Great River oil delivery orders go out same-day or next-day, and our optional Howes winter fuel treatment protects your supply during the coldest stretches near Islip and Oakdale.
