Marran’s automatic heating oil delivery keeps track of your oil usage to ensure that you’ll never run out of oil. Our state of the art software creates a customized calculation for your home, so that you don’t have to think about it. We take into account weather and your oil usage throughout the year to deliver oil when you need it.

Marran is the oldest family owned oil company on Long Island. We started delivering lamp oil by horse drawn carriage in 1891, at a time when the competition was still offering coal. We’re still family owned and operated today, and we still utilize the latest technologies to ensure that your house stays warm all winter.
