Why Greenlawn homeowners choose us

Nearly five decades of dependable heat

Greenlawn homeowners want a heating oil company that treats them like people, not account numbers, and that is exactly what OK Petroleum has done since 1976. Our decades of home heating oil delivery across Suffolk County and greater Long Island have made us a name Greenlawn families recognize and trust.

We believe pricing should be simple and honest. Every order shows a transparent per-gallon rate before you confirm, with no hidden fees added afterward. Order anything from 50 gallons to a full 500-gallon fill, and rest assured the price you see is the price you pay, which makes planning your heating oil budget painless.

Being family-owned and local means we move fast and answer to you directly, without a call center in the way. Most Greenlawn oil delivery orders arrive same-day or next-day, and when a cold Long Island night settles in near Huntington and Northport, our optional Howes winter fuel treatment keeps your heating oil from gelling.
