Avfuel Corporation
C.R. Sincock II leads Avfuel, the family-held fuel and logistics network supplying nearly a third of branded aviation fuel at US FBOs.
Avfuel Corporation
Avfuel Corporation was founded in 1970 by the Sincock family and has remained privately held for two generations, with C.R. Sincock II serving as Executive Vice President. The business originated as a regional fuel supplier in Michigan and expanded through a unique dealer-cooperative model that bundles thousands of independent fixed-base operators under shared brand standards, volume purchasing agreements, and loyalty programs. The Sincock family has never sold equity or taken outside partners, making the corporation an integrated operating business and de facto family office with a permanently concentrated balance sheet. The firm's core strategy marries fuel distribution with technology-enabled services. On the distribution side, Avfuel supplies Jet A, Avgas, and sustainable aviation fuel (SAF) to over 650 FBOs globally, alongside contract fuel programs for corporate flight departments, fractional operators, and charter fleets. The firm has been an early mover in SAF logistics, signing offtake agreements with producers like Gevo and Neste (per Reuters, 2023) and operating a dedicated trucking fleet to deliver the fuel to airports including Van Nuys and Monterey. On the technology side, Avfuel owns Avplan Pro, a flight-planning platform used by thousands of pilots, and launched an emissions-reduction program called Avfuel Zero that lets aircraft operators purchase verified carbon offsets and SAF credits. Geographic coverage spans North America, with growing SAF delivery capability in Europe. Headquartered in Ann Arbor, Michigan, Avfuel maintains additional operational hubs in Texas and Washington state to manage logistics and fuel-contract administration. The firm does not disclose headcount or total revenue, but industry estimates place its annual fuel volume above one billion gallons, making it the largest privately held aviation fuel supplier in the US (per Aviation Week, 2022). Adjacent operations include a full-service charter and aircraft management division, Avflight, which operates FBOs in multiple states and at major cargo hubs such as Willow Run Airport. In July 2024, Avfuel and Avflight jointly announced the opening of a renewed FBO at Willow Run with dedicated SAF inventory, signaling continued infrastructure investment in the cargo and business-aviation corridor between Detroit and Chicago. Avfuel's structural differentiator is its dual identity as an operating business and a family-controlled investment vehicle. The Sincock family uses the corporation's steady fuel-margin cash flows to fund vertical acquisitions — fuel logistics, technology platforms, and real estate at airports — without ever recycling investor capital. This architecture eliminates fund-duration pressure and allows Avfuel to hold assets indefinitely, from fuel farms to software IP, in a permanent-capital structure that resembles an endowment but distributes no external returns.

Frequently asked questions
Who makes investment and strategic decisions at Avfuel?
C.R. Sincock II runs the firm as Executive Vice President alongside second- and third-generation family members in senior leadership roles. The Sincock family has never opened the equity to outside investors, so all capital-allocation and acquisition decisions are made internally without an investment committee structure visible to the public.
How does Avfuel deploy the cash flows from its fuel distribution business?
Cash flows from the branded-dealer fuel network are reinvested into vertical acquisitions — SAF logistics capabilities, flight-planning software such as Avplan Pro, fixed-base operator real estate through sister entity Avflight, and the Avfuel Zero carbon-offset platform. The firm does not report a formal separate investment vehicle; all investments appear to sit on the operating company's balance sheet.
Does Avfuel operate like a traditional single family office or is it exclusively an operating company?
It is a hybrid. Avfuel Corporation is an operating business at scale, but its permanent capital structure and pattern of acquiring adjacent businesses — fuel-logistics providers, technology platforms, and airport real estate — functions as a single-family investment vehicle. The Sincock family uses the corporation rather than a separate family office entity to hold and compound wealth.
How is Avfuel exposed to sustainable aviation fuel and the energy transition?
Avfuel has been an early SAF logistics partner, signing offtake agreements with producers such as Gevo and Neste, and operating a trucking fleet to deliver blended SAF to US airports. The firm also runs Avfuel Zero, an emissions-offset and SAF-credit marketplace that lets pilots and flight departments address Scope 1 emissions. These initiatives show a view that the SAF supply chain will be critical to business aviation over the next decade.
What is the relationship between Avfuel and Avflight?
Both are held by the Sincock family. Avflight Corporation operates a network of FBO locations and aircraft-management services, complementing Avfuel's fuel-supply and technology businesses. The two entities co-invest in real estate, as seen in the July 2024 Willow Run FBO expansion, but operate as distinct companies with shared ownership.
