A Legacy of Service. A Commitment to You.
A lot has changed since Molo entered the energy business in the 1870s. One thing, however, has remained constant: our commitment to serving customers like you.
We are not a huge multi-national company. We are a family business whose goal is to take care of other families. Starting in Dubuque, Iowa, we have grown steadily over the years into the six states where we operate today. And we plan to continue that growth into the next generation.
Molo Petroleum considers no phase of its operations or administration of greater importance than employee health, safety, and accident prevention, read more about our affilitations and recognitions.
As we continue to grow and expand, we will remain focused on the energy business—and just as focused on continuing that legacy of service.
Molo also believes it’s important to support our communities and those organizations that are vital to the quality of life in the areas we serve. Part of that support includes active engagement in corporate giving initiatives Learn more about what we support.
