Walker Sims Oil Company, Inc. was started in 1981 in Seminole, Texas. Company founder and president, Walker Sims, began by providing fuel, lubricants, and chemicals to agricultural and commercial customers in the area. Since that time, the company has expanded its territory with a second location in Slaton, Texas, in order to better serve customers across a wider geographic region.

We remain a family-owned business that strives to provide exceptional customer service with quality products on a daily basis. We currently offer wholesale quantities of both highway and off-road diesel, gasoline, propane, and a wide variety of lubricants and greases.
