Poultry & Agriculture

From the beginning.

The McMahan Poultry Company began in 1946 with Lee D. McMahan. A few years later, he purchased a used oil truck to deliver fuel to his own poultry houses for efficiency. Soon thereafter, neighboring poultry farmers wanted the same personalized service. So, Mr. McMahan started delivering fuel to them as well. And that’s how Tri Gas & Oil began.

“Our grandparents began our heritage in poultry, their legacy is why Tri Gas & Oil prides itself on serving the poultry industry here on Delmarva,” says Nash McMahan, President of Tri Gas & Oil Co., Inc.

Soy Biodiesel – Renewable Energy, Clean Burning

Biodiesel is a clean burning fuel that is renewable and domestically produced. Biodiesel can be blended at any level with petroleum to create a blend. In most cases, few or no modifications are needed to use biodiesel in any equipment that consumes regular diesel. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.

Tri Gas & Oil is one of the largest distributors of soy-based biodiesel in Maryland, Virginia and Delaware. Custom blends of soy biodiesel can be created to customer specifications. From B2 to B99.9, the product can be delivered in quantities as small as 500 gallons to as much as 7,000 gallons. B100 is also available at our Federalsburg office for drive-up customers.
