About Tri-Gas & Oil

Tri-Gas & Oil Co., Inc. was established by Lee D. McMahan and Gilbert Banning in 1963 with a concentration on supplying fuel to neighbors and the poultry industry. As Tri-Gas & Oil grew, we began providing propane gas storage, custom blended oils, and also transporting propane gas and petroleum products straight from the refinery. Tri-Gas & Oil is a locally owned, family-run business that truly cares about providing excellent fuel service while supporting the communities we serve.

Today, Tri-Gas & Oil provides energy solutions for customers throughout the Delmarva region with propane gas, oil products and alternative fuels for home, agriculture and industrial uses. We are one of the largest distributors of biodiesel in Maryland and our distribution services extend beyond Maryland and Delaware to commercial and agricultural consumers located in the mid-Atlantic region.

  • To the Management of Tri Gas & Oil Company,

    We walked into our house after midnight on Friday, February 10, to a very cold house, with no propane.  I immediately called Tri Gas, and was told that my account was set up for "will call" vs. automatic.  Regardless of why or how that happened (I changed that this morning), I am writing to tell you about the level of service I received from your employees.  The woman on the phone could not have been nicer or more helpful.  The two trucks appeared within an hour.  My concern about how to re-start everything was quickly answered by Jeff, "That's why I am here!"  After the tank was filled, Jeff came into the house and made sure everything was re-started, and all were working properly.  All, with a wonderfully kind attitude - realizing that they were dispatched at 1AM in the morning!

    As an owner of my firm, I know how hard it is to combine talent and customer service personality.  Tri Gas has obviously found a way to do that.
    take care
