Beginning on September 1, 1967, Hattiesburg 66 was founded as a branded Phillips 66 jobber. With the addition of handling Gulf Products the company changed it’s name to Big K Oil Company, Inc. Recently with the leasing of its operation that used “Big K Food Stores” the company has renamed to KeithCo Petroleum Inc.

In late 1972, the company expanded from full service gasoline stations and began to serve convenience stores with gasoline pumps. The company installed its first pumps in front of a food store with the hopes that this would allow more competitive pricing. It also made it easier to meet the financial obligations of the food store, since they were already surviving financially without fuel sales.

In 1973 and 1974, “gas shortage” prevented growth. However, in 1975, the company began to expand again through the installation of gas facilities at convenience stores.

In March 1977, the company began to purchase gas from Gulf Oil Company. The company continued to place emphasis on gas facilities at convenience stores. By staying open longer hours and pricing on a more competitive basis, substantial increases in volume were made.

1979 through 1981 was a period of fast growth within the company as it began to remodel and rebuild outdated units. Self-service gas had become a way of life for many consumers. Full service stations, as we had known them were a thing of the past.

In 1988, the company was looking for continuous growth and expansion by adding another product line. In October the company became a Chevron jobber.

In 2004, Keithco became a Shell and a Texaco Jobber.  This opened new doorways for us in Mississippi, Alabama, and Louisiana.

Keithco currently supplies Shell, Texaco, and Chevron branded locations in the three states as well as numerous unbranded locations.
