Why Port Jefferson homeowners choose us

Trusted North Shore oil delivery since 1976

Port Jefferson homeowners have counted on OK Petroleum since 1976, and that longevity is no accident. We are a family-owned home heating oil company that treats every delivery in this corner of Suffolk County as a promise to keep a household warm. When the harbor winds pick up and temperatures drop, you want a supplier that answers the phone and shows up, not a faceless call center.

Fair, transparent per-gallon pricing sets us apart for Port Jefferson families. You see your exact price before you check out, with no hidden fees, delivery surcharges, or surprises tacked on later. Whether you order 50 gallons to get through a cold snap or a full tank fill, the number you confirm online is the number you pay.

Reliability is the rest of the story. Most home heating oil orders across Port Jefferson and nearby Port Jefferson Station arrive same-day or next-day, and our local drivers know these North Shore streets. Nearly fifty years of oil delivery on Long Island has taught us that dependable service beats every gimmick, and that is what we bring to your door.

Your local Port Jefferson heating oil supplier

A family-owned Long Island company

OK Petroleum started as a local Long Island operation in 1976, and nearly five decades later we are still family-owned and family-run. We are based in Hauppauge, just a short drive from Port Jefferson, so serving this Suffolk County community is close to home for us in every sense.

Our drivers live and work on Long Island, which means they know Port Jefferson's harbor-side neighborhoods, its hilly streets, and the way North Shore winters test a heating system. That local knowledge lets us route home heating oil deliveries efficiently and get to your tank without the delays a regional outfit would hit.

More than anything, we are committed to keeping Port Jefferson homes warm. Generations of families here have trusted us with their heating oil, and we do not take that lightly. When you order from OK Petroleum you are supporting a neighbor, not a corporation, and you get the friendly, straightforward service that has defined us since day one.
