Family-Owned and Operated Since 1976
At OK Petroleum, we’re more than just a fuel company—we’re family. Since 1976, our family has proudly served Long Island with the same values we started with: honesty, reliability, and personal care. Being family-owned and operated means every customer matters to us. We live and work in the same communities we serve, and we treat our customers like neighbors—because that’s exactly who you are.

Wholesale Motor Oil Distribution
In addition to serving homes and businesses locally, we’ve built a strong reputation as a trusted wholesale distributor of motor oils and lubricants. Through our OK Petroleum Marketplace, we provide garages, service stations, fleets, and businesses across the country with top-brand motor oils, synthetic lubricants, antifreeze, transmission fluids, and more. Buying in bulk with us means cost savings, consistent supply, and the convenience of ordering online—all backed by the same family commitment to quality service.

Home Heating Oil
For thousands of families across Long Island, heating oil is at the heart of staying warm through winter—and we’re proud to deliver it when you need it most. Whether you prefer will-call or automatic delivery, we make it easy to order online and count on reliable service at competitive prices. With over four decades of experience, we know how important timely deliveries are, especially when the cold hits. That’s why our customers trust us year after year to keep their homes comfortable, safe and warm.

Gas Stations
We also keep Long Island moving with our full-service gas stations across Nassau and Suffolk counties. Conveniently located, our stations offer more than just gasoline—you’ll find motor oil, antifreeze, and other automotive essentials right at the pump. Our stations are run with the same dedication to customer service that we bring to every part of our business, making it easy for drivers to fuel up and get back on the road quickly.

Whether you’re heating your home, running equipment, or keeping a commercial fleet on the move, you can count on us for safe, timely, and reliable deliveries. With flexible scheduling and competitive pricing, our fuel delivery services are designed to give you peace of mind and the dependable energy supply you need.
