A Family-Owned Fuel Delivery Company Since 1929
Our story began in Bethlehem with one truck, three family members and a mission to serve. We started by delivering block ice, then expanded into heating oil and coal. By the 1970s, Deiter Bros. had grown into one of the largest fuel providers in the region. Today, we continue to lead as a full-service fuel delivery company offering heating oil, propane, diesel and gasoline services.
Over the decades, we’ve added commercial fueling solutions and automated delivery options. Though our services have evolved, our mission remains the same: to serve customers with respect, responsiveness, and reliable fuel when they need it most.
