Hello everyone!

Welcome to this month’s installment of Company Of The Month here on oldgas.com!

This month’s feature will cover the Mid-Continent Petroleum Corp. (D-X Sunray, Sunray D-X, Sunray Mid-Continent). I’ll start off with a brief history, a timeline, and then we’ll start posting pictures of signs, globes, cans, pumps, maps, and everything else that we can find. I hope to get a lot of participation, as Mid-Continent / D-X is fairly popular, and one of my favorite brands.

I would like to thank Wayne Henderson, Bob Drake, and Scott Shipers for helping me put this together so far, and I’m sure I’ll have many more of you to thank by the end of the month.

So, let’s get started!

Company History:

The history of Mid-Continent is somewhat fuzzy, due to the extreme complexity of the businesses involved in its formation and the limited availability of records from this period.

It all started with Josh Cosden of Tulsa, Oklahoma in the mid teens. Mr. Cosden, a prominent businessman and local celebrity in Tulsa, is briefly described in this article from the Harvard Business School:

“Known as the "prince of petroleum," Cosden is credited with establishing Oklahoma as a major oil producing state. Starting with a small parcel of land, he built a $35 million oil business in ten short years. Through his oil discoveries and exploration, he almost single-handedly quadrupled the population of Tulsa at the turn of the century.”

Mr. Cosden established Cosden Oil & Gas Co., building its new headquarters building (called the Mid-Continent building) in 1916. Mid-Continent Petroleum Corporation was organized as Cosden & Company, a Delaware corporation, in 1917. Various Cosden holdings were re-incorporated as Mid-Continent Petroleum during a forceful restructuring that took place in 1925. It was at this time that the Mid-Continent building in Tulsa officially became the headquarters of the Mid-Continent Petroleum Corporation.

The Washington Post stated in 1927:
”The company is a holding corporation, but through its subsidiaries produces and refines crude oil and distributes its products at wholesale. Oil properties owned are located in Oklahoma, Texas and Kansas.”

As of 1932, they were operating the following subsidiaries:
Cosden Pipe Line Co.
Kay & Kiowa Oil Co.
Cosden Oil & Gas Co.
Mid-Continent Petroleum Company of Kentucky
Cosden Sales Corporation
Cosden Building Company

Also as of 1932, Mid-Continent was operating a 40,000 bpd refinery at West Tulsa, OK, nine natural gasoline plants, production properties in Oklahoma, Kansas, Texas and Arkansas, 1300 miles of pipelines, and marketing from Texas to Canada throughout the Mid-Continent area.

The company’s stations began selling gasoline at stations under the Diamond name at some point in the early to mid- 1920s. The stations sold motor oil, kerosene, Diamond gasoline, and an anti-knock version known as Nevr-Nox. This antiknock compound must have been something other than Ethyl at the beginning, because it was touted as being “non-poisonous” on some versions of signs and globes from the 1920s through 1933.

In 1933, “D-X” gasoline was introduced. It is theorized that this name was in reference to “Diamond – X,” suggesting an “X-factor” or unknown substance in the gasoline that made it superior to others. The D-X name became more prominent, being applied to more than just gasoline. Eventually, by the end of WWII, stations were rebranded from “Diamond” to simply “D-X.”

In 1955, significant changes took place in the company. Because Mid-Continent was mainly a holding and marketing operation, it proved beneficial for them to merge with a heavily production-oriented company. In this case, that company was Sunray Oil.



This merger resulted in two new companies. The Sunray Mid-Continent Oil Co. was the production-oriented entity, and the D-X Sunray Oil Co. was geared primarily towards marketing and distribution. Stations continued to operate under the D-X name (changed to DX in or about 1957). Sunray stations added the D-X logo to the bottom of their logos at the time of the merger, but by 1962, all were rebranded to DX.

This Sunray advertisement is from 1959:


Also in 1962, a name change took place for DX Sunray. The positions of the names were reversed, yielding the Sunray DX Oil Company.

1968 brought about the end of Sunray DX, as a merger with the Sun Oil Company (Sunoco) resulted in its dissolution. The DX stations located in Sunoco marketing areas were rebranded, but the stations outside of these areas remained DX until after 1980. It was in this year that Sun began to rebrand all of the DX stations gradually, the last of which disappeared in the mid-1990s.

Stay tuned for more information and photos. Up next is the company timeline, followed by station pictures and more!

I'm impressed so far! I didn't have the courage--or the resources--to tackle this company.

We had a fully operational DX station until 1992. Haven't seen one since.

Let’s start out with a few old station images.

Here’s a picture from 1931 of a Diamond station in the process of being built. The station building itself is complete. Notice the visible pump lying on the ground in a crate, and the first-generation station ID sign on the pole.


Here we have an advertisement from a building/signage company with an extremely cool Diamond facade.


Here is a Diamond service station building in Louisville, KY. It was built in 1927 in the mission style, and has some very cool diamond-shaped tiles on the pillars. Notice the metal brackets above the two main arches. These are likely from a Diamond Service Station porcelain strip sign.


Here’s an image of some clockface pumps at a D-X station in the mid 30s.


And a much newer DX station… From gassigns.org: Abandoned DX on US 77, south of Wynnewood, OK about to be demolished.

Hey Norm, thanks for the pictures! I sure like that Diamond sign... I was wondering if you were ever going to dig that thing out

Let's take a look at some globes!

I've compiled all of the globe images I can find so far. If you know of one that I've omitted, please let me know, and I'll gladly correct the situation.

Here we go...

The first six globes are from the 1920s, exact year unknown...
