What G&S Oil Products does
G&S Oil Products is a family-owned, private Colorado retailer operating company-owned convenience stores, fuel stations, and auto service facilities across the Colorado Front Range. The company was founded circa 1964 by Meyer Sussman after he purchased the gas station where he had worked his way through the University of Denver. Over subsequent decades, G&S expanded throughout Denver, Boulder, and Colorado Springs, and at one point operated a wholesale fuel distribution business serving independent operators in the region. Today, the company operates 8 convenience stores under Conoco sub-brands (including DU Conoco, Bear Valley Market, Erie Conoco, Downing Street Market, Yosemite Conoco, Berthoud Conoco, Circle Drive Conoco, and Franktown Market) plus 2 ASE-certified auto service stations (South Downing Conoco in Denver and Broadway Estates Conoco in Littleton). The Circle Drive Conoco is temporarily closed for reconstruction with a planned reopening in Summer 2026.
The business derives revenue from four streams: convenience store retail (food, beverages including beer and wine at select locations, groceries, lottery, and local specialties such as Rico's burritos and Little Man Ice Cream); fuel sales (gasoline at most locations, diesel at select sites including Franktown Market with big-rig access, and Phillips 66 fuel at Bear Valley Market); automotive repair services performed by ASE-certified mechanics (oil changes, brake service, computer and engine diagnostics, transmission repair, alternator service, and other maintenance); and ancillary services (car washes, propane exchange, ATM, mobile pay, air/vacuum stations, gift cards, and the KickBack Customer Rewards loyalty program). Distribution is exclusively through company-owned physical retail locations; there is no e-commerce, marketplace presence, or third-party distribution. The customer base is primarily local Colorado Front Range consumers and commuters, with Denver University students, faculty, and visitors as a secondary segment served through the campus location.
The technology stack is conventional for the convenience/fuel and auto service categories: standard automotive diagnostic equipment at the service stations and point-of-sale systems at the retail counters. In 2022, the company divested its wholesale fuel distribution division to focus exclusively on retail operations. Jeff Sussman joined as Executive Vice President in 2010, and the Sussman family retains controlling ownership with the third generation now involved in the business. G&S maintains an active community engagement program, including 11+ years sponsoring DU Athletics and supporting numerous Colorado-focused nonprofits. The corporate headquarters is at 6800 S Dawson Cir Ste 201, Centennial, Colorado.
