More About Us

Since 1976, OK petroleum has been meeting Long Island's heating oil demand and in that time, we have become the premier heating oil supplier for the residents and business owners of both Nassau and Suffolk Counties. The key our success lies in our policy of putting our customers first. 

At OK Petroleum, we know that when it comes to your heating oil Long Island needs, you want to work with a supplier that you can count on. 

Unfortunately, over the 40 years that we have been in business, we have seen far too many people get swindled by companies that promise they are going to deliver quality products at affordable prices, but what those companies say and what they actually do are two totally different things. 

At OK Petroleum, we actually mean what we say. We promise to provide you with reliable service, the highest quality products and the most affordable prices – and we always deliver on our promise.  Just ask one of the countless satisfied OK Petroleum customers and hear what they have to say for us yourself!
