Sinclair is nearly 100 years old, but we couldn’t have lasted this long if we didn’t stay ahead of the times. We combine old-fashioned values with tomorrow’s technology for cleaner, more powerful products.Sinclair owns and operates two refineries in Wyoming. The combined capacity of the two plants exceeds 110,000 barrels per day, making Sinclair Oil Corporation the largest refiner in the greater Rocky Mountain region.The Sinclair Refinery is the larger of Sinclair’s refining operations. It is the most sophisticated and complex refinery in the region, capable of processing a variety of crude oils, from heavy sour to light low sulfur crudes that are produced in Canada, North Dakota and Wyoming. The refinery produces high quality products including regular and premium gasoline, diesel fuel, jet fuel, propane, butane and road asphalt.
